To say that we like travel backpacks may be the best example of an understatement we can give. And, the bigger they are, the more features and functions we can explore along with you. Sometimes though, bigger isn’t always better, and in those cases, we need to step it down a bit.

Aer Travel Pack 3 Small Outdoor Back
Aer Travel Pack 3 Small | It’s the Travel Pack 3, but put through the shrink ray.

Fortunately, that doesn’t always mean a step backward in functionality as well. The Aer Travel Pack 3 Small is exactly what it sounds like: it’s a slightly smaller version of the Travel Pack 3. Yes, it doesn’t have as much space as its bigger sibling. But at the same time, its size is a much better fit for those with smaller frames, and it’s friendlier to carry-on compliances.

Plus, all of the features that we like on the bigger version, such as the load lifters, built-in smart tracker pocket, and big bucket-style main compartment—they’re all still there. If you’re looking at the Travel Pack 3 thinking it’s just a bit too big for your needs, let’s see if this one hits the Goldilocks Zone.

Materials & Aesthetic

We say that the Travel Pack 3 Small is a “slightly” miniaturized version of the original because, at 28 liters, this bag is by no means minuscule—in this case, “small” is a relative term. We’d say that this bag can be better described as “condensed” because, on the surface, it seems to have inherited all the bells and whistles of its bigger brother.

Aer Travel Pack 3 Small Brand
Aer Travel Pack 3 Small | The small Aer logo is much easier to spot at this smaller size.

It features the same rounded rectangular shape with the signature zippered opening running across the front. Straps, seams, and zippers are scattered all across the different areas of the bag. However, the Travel Pack 3 Small still maintains Aer’s more reserved and minimalist styling that goes oh-so-well with the sleek all-black aesthetic we’ve come to know them for.

Compared to the older Travel Pack 2 Small, the Travel Pack 3 Small looks cleaner in some respects while gaining additional elements in others. All of that said, regardless of whether you’re comparing the Travel Pack 3 Small to its bigger sibling or to its predecessor, Aer’s consistent design language ensures that there’s nothing visually drastic between any of them. Put another way, there’s a good chance people won’t know you’ve switched bags unless you tell them otherwise.

Aer Travel Pack 3 Small Zipper 2
Aer Travel Pack 3 Small | The zipper pulls are noticeably more stout versus the old ones.

The main material is still Aer’s fabric of choice: 1680-denier CORDURA Ballistic Nylon, a highly abrasion-resistant fabric that holds up well against daily wear and tear. That’s one of the main perks of a heavy denier nylon-based fabric like this one. If you want something more eye-catching, then the Olive colorway is certainly worth considering. It uses the same 1680D CORDURA® Ballistic Nylon the black colorway uses, so it’s no less durable than its black counterpart, but we like the subtle style it adds.

Then there’s the Gray colorway, which does use a different material. It’s still a fabric made by CORDURA®, albeit with a lighter at 700 denier. That said, our experience with lighter denier’ed gear from Aer has generally been positive, most notably with the Aer Duffel Pack 2. It might not hold up as well as 1680D fabric in more extreme use cases, but it’s more than enough if you’re just taking it around the city.

Aer Travel Pack 3 Small Buckle Top
Aer Travel Pack 3 Small | Nope, not Fidlock. These magnetic buckles are from Woojin.

The list of high-quality materials doesn’t stop at just the fabrics. All of the zippers on the Travel Pack 3 Small are YKK-branded, which is pretty much the gold standard for zippers. The accompanying metal pulls appear shorter than the old ones, but they’re also noticeably wider, which minimizes metal-on-metal contact between them. To top it off, cord pulls are also attached to the metal ones, which dampen any jingly noises.

The plastic strap adjusters are from Duraflex, while the magnetic buckles are from Woojin. Both brands are as reputable as YKK, and we do see all three names pop up in one bag from time to time. And yes, new to the Travel Pack 3 Small is the use of magnetic buckles, which we’ll discuss more in the next section.

External Components

Aer didn’t hold back with the Travel Pack 3 Small’s harness system. All of the goodies on the bigger version are here, from the standard well-padded shoulder straps down to the magnetic compression straps. We’re glad to see this because the “small” version of regular gear often gets stigmatized as the cut-down, budget version, which is clearly not the case here.

Aer Travel Pack 3 Small Strap
Aer Travel Pack 3 Small | We can also put on a hip belt in case we feel a little extra.

The shoulder straps have enough width and padding to spread out the potentially enormous weight that can be loaded into the 28-liter capacity. The straps are slightly wider than the old version’s, but the bulk of the difference can be traced to the newly-introed load lifters. These straps make a welcome return on the Travel Pack 3, where they have a substantial impact on carrying comfort. The good news is that they also have the same helpful effect on the Travel Pack 3 Small.

In a nutshell, the job of load lifters is to pull the bag closer to your shoulder area, effectively minimizing the saggy or being-pulled-back feeling. Tightening the load lifters on the Travel Pack 3 Small achieves this and better centers the weight of the bag, resulting in a more balanced carry. Oh, and fans of the dangle-free look will be happy to know that there are strap keepers built-in directly near the top of the shoulder straps to keep the load lifters’ slack tamed.

Aer Travel Pack 3 Small Adjust Buckle
Aer Travel Pack 3 Small | These load lifters help better center the bag’s weight.

The shoulder straps themselves have a few other built-in features apart from those already mentioned. They’re length adjustable (as expected), but they also come with elastic strap keepers to preserve the bag’s clean looks. There’s a lone D-ring on the right shoulder strap for attaching additional accessories. On the opposite shoulder strap, there’s only a small Aer logo on a Hypalon tab—not functional, just decorative.

Of course, the shoulder straps also come with a removable sternum strap for added support (this is still a big bag, after all). It’s the kind we like, too: the type that slides along a rail and has a fine degree of adjustment. What we’re not fans of, though, is the magnetic buckle.

Aer Travel Pack 3 Small Sternum Strap
Aer Travel Pack 3 Small | We’re just not fans of magnetic sternum straps.

Yes, the hardware is from Woojin, a brand we typically like. However, we think magnetic buckles are a bit unnecessary in a sternum strap. Side release buckles clip on and off very easily. On the other hand, magnetic buckles need to be slightly but noticeably pushed together to unclasp. When you already have a sternum strap well-fitted, pushing them together can be somewhat discomforting. Plus, it’s harder to undo with one hand, which is inconvenient if you’re holding a pre-flight coffee but want to set your bag down.

That said, we don’t want to over-exaggerate this nitpick. The magnetic buckle gets the job done with the added benefit of the satisfying tactility unique to magnets. It just feels like more of a sidegrade than an upgrade.

Aer Travel Pack 3 Small Detail
Aer Travel Pack 3 Small | These narrow nylon loops are where the optional hip belt attaches.

In case you absolutely need more support on top of the load lifters and sternum straps, there is an option to attach a hip belt. Aer sells their own hip belt, but since the attachment points are simple nylon loops, it’s fairly easy to find third-party accessory straps that can fill the role. Is a hip belt necessary? That depends. When we took both the Aer Travel Pack 3 and Travel Pack 3 Small to Thailand, we were maxing out the latter’s space despite being packed with generally lighter clothing than the former. We could tell that the Aer Travel Pack 3 felt denser, which made using the hip belt almost crucial to shifting some of that weight off the shoulders. However, on days of the trip when we were not packing it too tightly, the built-in straps do a fine enough job managing the more loosely packed weight.

What good are shoulder straps without a supportive back panel? The foam padding on this pack feels a bit stiff out of the box, but that should get better over time as the material breaks in, and it’s not uncomfortable by any means. The two foam panels form a central air channel where a luggage pass-through sits flush. With its orientation, the Travel Pack 3 Small sits horizontally on a roller—not ideal if you have a lot of loose items inside that can get tossed around. Fortunately, we use packing cubes all the time, so that’s not an issue.

Aer Travel Pack 3 Small Carry Handle
Aer Travel Pack 3 Small | The sideways orientation can mess up loose items inside.

The Travel Pack 3 Small’s back panel has an interesting characteristic that’s fairly easy to miss. Looking closely around the top section from the side, you’ll notice that it wedges out quite a bit. This allows the back panel to contour around the shoulder area in conjunction with the load lifters. It’s a neat attention to detail we also notice with the Travel Pack 3—well done, Aer.

The Travel Pack 3 Small also has a complete set of handles for quick-grab duties. There’s one at the top, one at the bottom, and one on both sides. You can also technically use the luggage pass-through at the back as a handle, though we’d rather use one of the others first.

Aer Travel Pack 3 Small Carry Handle Studio
Aer Travel Pack 3 Small | The top handle has been slimmed down to better match the bag’s smaller size.

Interestingly, the top handle is significantly thinner than the one in the Travel Pack 2 Small, which is a good thing. The previous version’s handle is a little too beefy for its size, and the Travel Pack 3 Small’s top handle is much more proportional. As an aside, we wish Aer also put a small loop between the shoulder straps so that we could hang the bag easily on small and shallow bathroom hooks. The top handle is way too inland for that purpose.

The side handles have a slick seatbelt-like texture and are somewhat padded for comfort. However, they do stick out of the sides quite a bit, enough for them to get caught on a doorknob in one instance. Thankfully, no one was hurt in that incident, including the door.

Aer Travel Pack 3 Small Side Handle
Aer Travel Pack 3 Small | The side handles jut out, making them prone to catching on doorknobs and other objects.

Another thing to note is the addition of compression straps on the Travel Pack 3 Small, which are lacking on the Travel Pack 2 Small. This allows you to tighten it down for easier everyday carry.

We don’t find them super necessary in keeping the bag’s weight compressed. Again, the load lifters do a good enough job on their own. On the other hand, the compression straps help the bag maintain a slimmer profile when it’s empty. At 28 liters, it’s a lot more everyday carry-able than its larger sibling, but your mileage may vary depending on your preferences.

We have to note that the compression strap below the right side water bottle pocket tends to disengage on its own, most likely due to a momentary loss of tension and sudden jolt on the strap. Interestingly, we’ve observed that this “issue” is more prevalent on the larger Travel Pack than it is with the Small.

Aer Travel Pack 3 Small Water Bottle
Aer Travel Pack 3 Small | The magnetic compression straps pull double-duty, but we’re still iffy about them.

Lastly, there’s a fold-flat water bottle pocket on the right side. It expands by undoing the zipper that runs down the middle, which reveals the stretchy mesh material. The pocket is large enough to fit an 18-ounce bottle like a YETI Rambler, but anything larger may struggle to fit. The elastic doesn’t really maintain a firm grip, so we recommend utilizing the D-ring or the compression strap just above to anchor your bottle’s handle (if it has one).

Inside The Pack

On the opposite side of the bag is a quick-grab pocket where we put some handy small accessories. These include wireless earphones, a wallet, and a packable bag. Do note that by packable bag, we don’t mean relatively big ones like the WaterField Designs Packable Backpack. We mean more along the lines of Matador’s Droplet Packable Dry Bag and BAGGU’s Standard Baggu Tote—very small, very simple packable bags.

Aer Travel Pack 3 Small Side Pocket
Aer Travel Pack 3 Small | There’s enough space for very small packable bags like the BAGGU.

Up at the top is Aer’s soft-lined pocket for easily scratched items like sunglasses and smartphones. We typically have our sunglasses in a separate protective case, but this is a nice inclusion for those who want to make do without one. Take note that this pocket has an all-black interior, whereas the rest have gray liner fabric. Smaller accessories like memory cards (which are often black) easily blend with fabric like that.

Next up is the front pocket. While the opening makes it seem like a split-type pocket, all of the space is in the lower half. There are no additional pockets inside despite all of the available space. It’s effectively a huge dump pocket where you can place something as large as a compressible jacket. There is a built-in key strap that’s fairly long with a robust-feeling clip—a far cry from the flimsier plastic ones on some of Aer’s earlier gear.

It’s worth noting that, due to the Travel Pack 3 Small’s being smaller than regular version, a lot of its pockets are also small (no surprises there). This is clearly demonstrated with the front pocket. Whereas we didn’t have trouble using the regular version’s front pocket as quick-access stash for a compressible jacket, the Travel Pack 3 Small’s front pocket just feels too tight for that purpose. Furthermore, stuffing the front pocket with bulky items can make it awkward to us the lower pockets on the admin panel.

Some of you who are looking to upgrade from the Travel Pack 2 Small may be disappointed to learn that the Travel Pack 3 Small omits the shoe compartment. To be honest (and we always are), that feature takes up a lot of space even when stowed away—space that could otherwise be used for something else. It’s not a huge loss for us, and it can be mitigated by using a separate shoe pouch from a brand like WANDRD or Peak Design. It’s an additional purchase, yes, but the amount of space saved is well worth it.

The vast majority of the Travel Pack 3 Small’s organization can be found in the front compartment. Here, you get an entire admin panel worth of pockets. Starting from the top, there’s a tablet sleeve, a zippered pocket that goes halfway down, two liner pockets with a pen silo in between, a mini stretchy mesh pocket, and two additional liner pockets. That’s more than enough to get most of our tech accessories organized, which includes our travel-sized mouse, charger, keyboard, memory cards, thumb drives, data cables, and laptop stand. Additionally, the compartment has more than enough independent volume that we can utilize the space in front of the pockets for fairly sizeable pouches, provided that they’re packed strategically.

Aer Travel Pack 3 Small 1 Compartment
Aer Travel Pack 3 Small | The layout is largely carried over from the Travel Pack 3.

When looking at this bag side by side with the Travel Pack 2 Small, it’s evident that Aer did a lot of cleaning up in terms of design. A lot of the stitching and seams are now less visible, lessening the overall visual noise inside the compartment. The liner fabric itself is less wrinkly and looks a bit bluer.

Just behind the front compartment is the main compartment. Much like the Travel Pack 3, accessibility here is relatively fast and easy since none of the compression straps go over the zippered opening. To note, it wasn’t an issue before in the Travel Pack 2 Small either since that didn’t have any compression straps to begin with.

Unfortunately, the zippers of both the front and main compartments can sometimes get caught up with each other. For example, if we have the bag lying on its back, the front compartment’s zipper pulls sometimes fall into the main compartment’s opening, which can be a bit annoying if you’re trying to quickly open your bag.

Aer Travel Pack 3 Small Zipper
Aer Travel Pack 3 Small | The zippers are lockable in case you need the extra security.

Having both compartments’ openings close to one another along the forward-most edge is worth the minor nitpick, though. It maximizes the main compartment’s volume by having the outer walls as high as they can be, therefore making packing a lot easier.

In terms of space, the Travel Pack 3 Small’s main compartment makes full use of the rated 28-liter capacity. There’s enough room for two large packing cubes plus a toiletry bag, though your mileage may vary depending on what packing cubes you use. Packing cubes are somewhat of a necessity to keep clothing organized since the main compartment lacks any built-in tie-down straps. This means clothing can shift around if it’s loosely packed. It’s worth noting that Aer sells their own packing cubes and pouches (the Aer Packing Cubes V2 and Slim Pouch, respectively), and they, unsurprisingly, fit perfectly in the Travel Pack 3 small. Of course, there’s nothing proprietary about the shape or fit, so you’ll likely find other pouches and packing cubes that fit just as well. All in all, the Travel Pack 3 Small is big enough for a week-long trip if you plan your packing list right and use the right organizers.

On that note, using the Aer Travel Pack 3 Small as a daypack is also viable. We’ve done it with the technically larger Tortuga Travel Backpack 30L, and the Travel Pack 3 Small is just as qualified. That is, so long as you don’t plan on fully maxing out the bag’s capacity since that almost necessitates using a hip belt, as we’ve mentioned earlier.

Aer Travel Pack 3 Small Main Compartment
Aer Travel Pack 3 Small | It’s enough for a short week-long trip.

Before we forget (because it’s so easy to miss), there’s a built-in smart tracker pocket hiding behind the top pocket’s liner. It’s a nice feature to include and makes the Travel Pack 3 Small feel like a bag fit for the decade we’re currently in.

The main compartment’s lid has a few organization options handy as well. There’s a wide zippered mesh pocket that we use as a catch-all space for semi-quick-grab items like extra toiletries that we might need in transit. Because it uses stretchy mesh, it has some room to expand for bulky items like socks or wool gloves.

Aer Travel Pack 3 Small AirTag
Aer Travel Pack 3 Small | There’s a dedicated pocket for smart trackers, so it doesn’t have to get lost in the mix with other items.

Behind the mesh pocket is a wide and very stealthy zippered compartment that covers almost the entire area of the lid. The limited depth limits its use for bulky items like a jacket or thick towels. Because of that, we opt to use the space as a dump pocket for extra straps, accessories, and items that we want out of sight for most of our trips but couldn’t exactly leave at home—everyone has one or two of those, right?

Aer Travel Pack 3 Small Interior Pocket
Aer Travel Pack 3 Small | The smart tracker pocket isn’t the only pocket here.

The last of the compartments is the laptop compartment. It’s good for laptops up to 16-inches—our 16-inch MacBook Pro fits with room to spare while our 13-inch MacBook is practically swallowed whole. Fortunately, there is a sleeve with a false bottom and cushioning at the back and front side for protection. If you’re not the type to carry around a tech pouch—or if the front compartment’s numerous pockets aren’t enough already—there is a zippered pocket at the top. This is a prime spot for a beefy laptop charger, but we mainly use it as a top-side pocket for our packable hat.

Aer Travel Pack 3 Small Laptop
Aer Travel Pack 3 Small | A 16-inch MacBook Pro also fits, and a charger fits in the zippered pocket as well.

Our key takeaway from the Travel Pack 3 Small is how uncompromised it is as a smaller version of the Travel Pack 3. It still has all of the features we like on its bigger sibling (and a few ones that we didn’t like as much), while its smaller size means it’s a better fit for users with smaller frames. If you find yourself liking the Travel Pack 3 but looking for something that’s easier to wield, look no further.
