The Sea to Summit First Aid Dry Sack is a lightweight dry storage option for protecting first aid, medical, emergency, and survival supplies (sold separately) from the elements. Easily identifiable with red fabric and the recognizable white “first aid” cross, it’s ideal for for river trips, the backcountry, and travel. Manufactured from lightweight PU-coated 70D nylon, it features a TPU clear window for easy identification of first aid kit contents. Its reinforced waterproof seams are double-stitched, and tape sealed, with a 10,000mm waterhead (the higher the waterhead rating, the more waterproof the fabric). The secure Hypalon roll-top closure features a D-ring for easy attachment. The Sea to Summit First Aid Dry Bag’s low-profile, streamlined shape saves space, and its oval base resists rolling. A patent-pending field repair buckle can be replaced in seconds with a Phillips screwdriver. Available in two sizes: 1 liter for day use, and 3 liter for overnight use.
