Helixot XO 6.2: A waterproof, fully submersible backpack

If you’re a frequent kayaker, stand-up paddler, or even a hiker who spends a lot of time in wet environments, you’ve probably dreamed of finding a backpack that’s completely waterproof. Sure, there are a few packs available that offer excellent protection from the elements, but very few of them are completely waterproof to the point that they are fully submersible. That isn’t the case with the Helixot XO 6.2 backpack — which is allegedly so airtight that it can keep your gear safe underwater.

Made from lightweight yet highly durable waterproof fabrics, the XO 6.2 is designed to safely carry a variety of small items on aquatic adventures. The pack offers 6.2 liters of storage capacity in its main compartment, which isn’t particularly large but is roomy enough to haul a small camera, smartphone, car keys, wallet, passport, and other items of similar size.
