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!

Sea to Summit says:

Using a 15D 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 30D Ultra-Sil® Dry Sacks!

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.

Light as a feather, extra strong

I've tested the 4 litre 19 g bag on a few missions stuffing it with underwear and socks. It did what it's made for. You must put it in your bag or backpack, it's waterproof and should not be submerged. Perfect for keeping any of your equipment dry.
