Sea to Summit's lightest dry sack
In the age of ultra-lightweight everything Sea to Summit has developed a range of ultra-lightweight dry sacks to save those crucial few grams. Using a 15 denier Sil/PU nylon fabric they call Ultra-Sil Nano, a lightweight side release buckle and a thinner roll top closure they have created a dry sack that is 30% lighter than their standard 30D Ultra-Sil Dry Sacks!
