Sea To Summit Ultra-Sil Nano Dry Sack
In the age of ultra-lightweight everything they 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 Sea to Summit have created a dry sack that is 30% lighter than their standard 30 D Ultra-Sil Dry Sacks!
