The SLNT Essentials Faraday Sling is a minimalist everyday carry option you can wear as a crossbody or waist pack. Perfect for everyday use, travel, and daily commuting, its standout feature is its built-in Faraday cage phone sleeve, which lets users go completely off the grid to prevent unwanted tracking and hacking. It also includes a separate EMF-reducing slip pocket, allowing you to stay connected while reducing EMF radiation exposure.

SLNT specializes in privacy-focused bags and accessories that incorporate Faraday cage technology. These devices allow users to block unwanted digital signals and protect themselves against tracking, hacking, and EMF radiation. SLNT products aim to safeguard users’ privacy while promoting a balanced approach to mental health by enabling them to truly disconnect from the digital world whenever and wherever they choose.
External Components
The exterior of the SLNT Essentials Faraday Sling features recycled 700D water-resistant material that feels both durable and premium. This durable material and a rigid back panel help maintain the sling’s structured form. The sling has reliable Duraflex hardware and YKK zippers, with exceptionally smooth gliding zippers for both the front and main compartments. While the design is streamlined, it lacks any kind of external grab handles or attachment points for additional gear. The SLNT branding adds a sleek aesthetic to the face of the bag, with an available all-black variant featuring the logo in black for those looking for a more discreet aesthetic.

The sling’s strap has a smooth texture and feel with an interesting webbing pattern reminiscent of ratchet belts or roller coaster seat belts. This texture seems to be more decorative and does not have any functional purpose. The strap has two plastic adjustment buckles: one that moves freely for quick on-the-go adjustments and another more rigid one built into the Duraflex side-release buckle permanently attached to one side of the sling. This side-mounted buckle is nice as it allows for quick removal.

Unlike a centrally placed release mechanism, this side-mounted release design can be nice as it prevents hardware from pressing against your body. The buckle is easy to connect and release, and you can make minor adjustments quickly, depending on your preferred setup. An elastic strap keeper nicely manages any excess strap length, preventing unwanted dangling.
Fit Notes

The SLNT Essentials Faraday Sling offers two carry methods: crossbody and waist pack. While looking more like a traditional waist pack, its unique design features a flat back design that sits comfortably against the body. While the rigid structure and back panel do not perfectly contour to the natural curve of a back, this did not present itself as a significant issue in use. However, the rigid form can feel somewhat awkward and weird when sitting on the side due to its structured form against the body.
Inside The Sling
The SLNT Essentials Faraday Sling includes their patented “silent pocket,” a Faraday cage phone sleeve with a secure magnetic closure. It is constructed with material capable of blocking all types of signals, including cellular, WiFi, Bluetooth, GPS, EMF, EMP/HEMP, key fobs, RFID/NFC, satellite/navigation, and even solar flares. The strong magnetic closure ensures that the contents remain secure and firmly shuts the compartment.

While the sleeve can fit larger phones, it is not exactly easy to use. The narrow opening requires larger phones like an iPhone 15 Pro Max to be inserted at an angle rather than horizontally, and the rigid, non-stretchy Faraday cage material demands that you use considerable force to insert or remove the device successfully. For the Faraday cage to function correctly, devices must sit below a certain level to allow for the magnetic closure to seal properly. While the iPhone 15 Pro Max ultimately fit, the force required to get it in and securely placed was slightly concerning. Users with smaller devices will likely have a much easier and smoother experience.
Between the Faraday cage phone sleeve and the main compartment, an EMF-reducing pocket acts as a quick access slip pocket for phones or other daily essentials. Unlike the Faraday cage sleeve, this slip pocket allows devices to maintain connectivity while still reducing EMF exposure. It is a convenient storage pocket for quick access to your phone or other essentials, making it perfect for freeing up your hands while staying connected. While the EMF-reducing capability is a nice touch, the pocket’s primary strength lies in its accessibility and ease of use.

The front pocket has a zippered closure with a front flap that adds an extra layer of weather resistance to protect the contents inside. The opening provides a nice overview and offers a decently spacious area for everyday essentials like keys, lip balm, and hand sanitizer. While this pocket does allow for a bit of expansion, it can still be somewhat limiting in capacity. Additionally, since it is located on the front of the sling, sensitive items like glasses are not recommended since they may be susceptible to impacts or damage.

The SLNT Essentials Faraday Sling’s main compartment has a single zippered opening at the top. While this is the main storage area, it offers less expandable space than the front pocket, making it more suitable for flatter items like phones or wallets. During testing, we could store an Ekster Wallet with AirTag and a small camera (Ricoh GR III) inside, although there were some slight concerns about storing the camera in such a tight space.

A built-in zippered mesh pocket inside provides convenient storage and organization for smaller items. This pocket has some stretch but seems to share space with the front compartment, which is worth considering when packing. It is an excellent storage solution for items like batteries, loose change, or USB drives.

The SLNT Essentials Faraday Sling offers a unique blend of privacy-focused features and everyday carry within a versatile sling. While the Faraday cage technology effectively delivers on its promise of signal blocking, the tight fit for larger phones and rigid structure may be drawbacks for some users. For those looking for digital privacy and EMF protection in their everyday carry, the SLNT Essentials Faraday Sling definitely stands out as a potential option despite its few limitations. The sling’s dual-carry options and thoughtful organization make it a practical choice for daily use, even when you don’t need its signal-blocking features. At its core, this sling is ideal for those looking to disconnect from digital tracking while maintaining a stylish, minimalist aesthetic.
