Ensure the dryness of your compressible gear with our Evac Dry Bag - where air exits but water remains barred. Crafted from a bluesign-approved recycled 70D nylon waterproof fabric for its main body and a 70D eVent® waterproof base that allows air passage while maintaining a dry interior, this bag maximizes space efficiency. Both fabrics feature DWR finishes that are C0 non-PFC. Effortlessly pack your compressible items like sleeping bags and insulated clothing into the Evac Dry Bag, seal it with the roll-top closure, and then expel air by squeezing the bag. This unique feature facilitates optimal packing into your backpack or travel bag. Designed with an oval base, these bags perfectly contour to your pack's shape. All seams are double-stitched and tape-sealed for added durability. Pro tip: Apply pressure by sitting on the packed Evac Dry Bag to expel air effectively. Then, stow the dry bag tightly within your pack to prevent it from refilling with air.
