Side Hydration Sleeve

The Hydration Sleeve is built from leftover materials from our camera packs, giving new life to premium fabrics through precision craftsmanship. Each sleeve is one-of-a-kind, with no option to select colors, making it as individual as your journey. Designed to hold hydration bladders or other essentials, it can be mounted on the sides or the back of your pack for adaptable storage. A clean magnetic closure keeps the pocket secure and easy to access on the move. Constructed with the same advanced techniques as our main packs laser cutting, RF welding, it offers exceptional durability and performance. Available only in exchange for an act of kindness, the Hydration Sleeve is gear with purpose, crafted to serve both you and the adventures ahead.

Act of Kindness

Instead of paying with money, this item can only be “purchased” with kindness. That means doing something small but meaningful for someone else or for your community—like helping a neighbor carry groceries, picking up litter in a park, mowing the lawn for someone who needs it, or simply offering a hand when it’s needed. By giving scrap material a second life, we also hope to inspire you to give a little bit of your time and care to make the world around you a little brighter.

I recommend this product

Well made, but unusuably ****

Good functionality, but thrown together without even a minimum of aestetical awareness. Red and black body, green cover, white(!) sides – to me not even worth the 16 Euros of shipping costs, sorry.

Hi Marko, Thank you for sharing your feedback. We’ve refunded your shipping costs, which should appear in your account within a few days. You’ll also receive an email with the address of one of our Ambassadors—please send the Hydration Sleeve to them, and we’ll cover the return shipping. The Hydration Sleeve is made from surplus materials from our camera bags, giving premium fabrics a second life through careful craftsmanship. Each sleeve is unique, with color combinations determined by the available off-cuts, and we limit them to one per person to allow as many people as possible to participate. This approach is part of our Zero Waste initiative, turning fabric that would normally be discarded into functional gear.
