In the age of ultra-lightweight everything we have developed a range of ultra-lightweight dry sacks to save those crucial few grams. Using a 15 denier Sil/PU nylon fabric we call Ultra-Sil® Nano a lightweight side release buckle and a thinner roll top closure we have created a dry sack that is 30% lighter than our standard 30 D Ultra-Sil® Dry Sacks!
Sea to Summit Ultra-Sil Dry Sacks are a super light weight dry sack designed for use inside a pack. Made from Siliconised Cordura for maximum durability Ultra-Sil Dry Sacks will keep your pack light and you gear bone dry! Ultra-Sil Dry Sacks use Beamis Seam Tape which is the highest quality available
All sea to Summit Dry Sacks use Hypalon instead of webbing on the roll top closure. Hypalon does not wick water into the closure unlike webbing Ultra-Sil Dry Sacks are constructed using Coats Brand threads which are the global leader in threads and sewing products. We use a short stitch length to ensure a high degree of quality Roll top closure is precisely designed with a longer Polypropylene stiffener opposite the Hypalon which helps seal the closure flat which further improves watertight seal and means that the roll top closure is less likely to unroll when under pressure
A custom designed shorter symmetric side release buckle can be clipped together either way around which also aids keeping the roll top closure secure All seams are top stitched which keeps taped seams flat and even 1 L 2 L & 4 L are flat rectangular shaped design. 8 L 13 L 20 L 35 L are round base design. All sizes in the Nano dry sacks have an oval base design.
I prefer using a range of drybags rather than a rucksack liner because you can keep your gear organised. These Nano Drysacks are very light, saving about 8grams on a typical size I`d use - this doesn`t sound like much but if you times it by 6 drybags that's 48grams - there are lots of bits of gear that I would take that weigh less than this - so 48grams is worth having!
Sea to Summit gear oozes quality and these Nano drybags are no exception - check out the oval base for easier stuffing into your pack.
