Full Review

If this messenger bag looks familiar, you’re probably a fan of TOM BIHN. Coming in at 5.8 liters, the Side Hustle is between the 3-liter Side Kick and the 6.5-liter Packing Cube Shoulder Bag and takes design elements from both. Will this transformation be delicious or taste awful like Polyjuice Potion? Let’s find out.

External Components

The exterior of this messenger bag is bluesign® certified High-Tenacity 2×2 Ballistic nylon. In typical TOM BIHN fashion, you can expect a lot from the materials, and the product page will let you know exactly what you’re getting, which we appreciate.

TOM BIHN Side Hustle Hanging
OM BIHN Side Hustle | We dig the classic TOM BIHN style.

There are a ton of colorways to choose from. We’ve got theDeep Blue Ballistic/Marigold 210 Cerylon on hand, which looks similar to other TOM BIHN packs we’ve tested. The logo has its trademark heritage styling, and overall, the pack feels durable, water-resistant, and versatile.

The zippers are from YKK and feel adequate for the job at hand. Extra pulls are included with the purchase, so you can switch things up if you so choose.

The hardware that attaches the strap is from Duraflex and works as we expect it to. It has a swivel and is easy to pop on and off. It doesn’t come unclipped when you don’t want it to, which is vital. There isn’t much else to report on that.

There isn’t a ton going on externally here. It’s a simple-looking pack, and that isn’t a diss. It’s sleek and stays out of your way while you’re wearing it, which is saying something because it is relatively large. It isn’t very deep; however, the footprint is more significant than expected for a 5.8-liter messenger bag.

Below where the strap attaches, there’s a small attachment loop where you could hook a carabiner. It doesn’t appear to be for that purpose, but you can use it that way if you want.

Fit Notes

TOM BIHN Side Hustle Side By Side
Left: Eric Hergenreder, Height: 6’0” (183 cm), Torso: 18.5” (47 cm) | Right: Kristyne Defever, Height: 5’5” (165 cm), Torso: 17’ (43 cm)

The strap has no padding or aeration; however, it’s reasonably comfortable, even when the pack is fully loaded. The clips are on a swivel, so adjusting the strap is easy if it gets tangled. However, because of the swivel, we’ve found that it gets tangled up easier, too. The strap is roughly 53 inches (134.62 cm) long when fully extended.

There’s no padding or aeration on the back panel, but we’ve still found that to be comfortable. It can get a bit warm, especially on hot days, but because of the design, it isn’t as bad as other packs we’ve tested. Because it’s a messenger bag, it isn’t typically in one place for an extended period, so the heat can’t build up. If this were a daypack on your back for longer, it might be a bit too hot.

TOM BIHN Side Hustle Strap
TOM BIHN Side Hustle | The strap is simple but comfortable.

The materials aren’t thick, so you can sometimes feel your gear stowed inside. This is especially true when you’ve got a lot of items loaded inside, so they’re protruding slightly. For the most part, it remains comfortable.

Inside The Messenger Bag

On the backside of the pack, there’s a compartment to stow gear. It’s a slip pocket with no closure, so it’s ideal for flat items like a book you might want quick access to on public transit or a walk through the park without going into the main pocket. However, because there’s no cover, it’s best to slide your gear into the main or front compartments in inclement weather. Anything you slide in here can be felt on your back, side, or front while wearing the pack, so flat items do best to maintain a comfortable fit.

TOM BIHN Side Hustle Front
TOM BIHN Side Hustle | You can wear this pack multiple ways.

Before we dive inside, the color and material of the liner depend on which colorway you go with. There are two options: bluesign® and OEKO-TEX® certified 200-denier Halcyon/nylon ripstop and bluesign® certified 210-denier Cerylon 6,6 Ripstop nylon. The model we have on hand is yellow Cerylon, which makes finding gear easier due to the bright colorway. Both the front and main compartments utilize this liner.

A slash pocket on the front of the pack works well for the quick-use gear you want to ensure has a topper, unlike the compartment on the backside. There’s no organization inside here—just open space. It’s ideal for stowing more oversized items, like a packable travel jacket, but it doesn’t work as well for smaller items not contained in a tech pouch or other organizer. The pocket takes up the entire front face of the pack so that you can stow a solid amount of gear here.

There’s one O-ring on the top of the compartment that comes with a key leash attached. You can move this to another O-ring or remove it completely if you so choose.

Moving into the main compartment, we’ve got more organization and, in typical TOM BIHN fashion, more O-rings.

The rings here are on the top of the compartment, too. There are two on either side, which brings the total for this messenger bag to five, which isn’t half bad. If you’re into math, that’s an O-ring for every 1.16 liters of the pack!

The front side has two large liner pockets. You can fit more oversized gear here—think a TI-84 calculator, Nintendo DS, or modern devices like a smaller Kindle. Neither one has a closure, so equipment can extend out of the top, which is helpful.

On the backside, there’s more organization. There’s a large liner pocket that can stow up to an 11-inch tablet, another pocket similar in size to those on the opposite side, a smaller one next door that works for a normal-sized phone, and two pen sliders that are large enough to accommodate a stylus for that tablet you stowed earlier. This organization is thoughtful but not necessarily dynamic.

TOM BIHN Side Hustle In Use
TOM BIHN Side Hustle | You have quick access to all your gear.

The area that fits a tablet lacks padding, so you’ll need a case to feel safe putting your device there. If you have a plus-sized phone, there isn’t a pocket perfectly designed to fit it, so it’ll either be a tight or loose fit, depending on where you put it.

That said, the organization works well for various gear and can accommodate just about anything. However, nothing feels designed with specific pieces of gear in mind.

The rest of the area is wide open. There’s a lot of space to work with, but it can be challenging to make the most of it. It’s tall and skinny, so, odds are, you’ll be stacking gear on top of other stuff to make it fit, making accessing gear on the bottom of the pack harder. It’ll work, but getting to it isn’t always easy.

The organization inside the main compartment feels as if it would work well if the sling was smaller. We loved the Side Kick, but the organizational details made more sense at 3 liters than at 5.8. We dig this pack; it just doesn’t feel as friendly or dynamic as other TOM BIHN gear.
