The Sea-To-Summit UltraSil® Nano Dry Sacks have been designed to save those crucial few grams. Using a 15D Sil/PU Nylon fabric called UltraSil® Nano, and pared-down components, Sea To Summit have created a dry sack 30% lighter than the already lightweight 30D UltraSil® Dry Sacks.
- Ultra compact and super lightweight dry sacks
- Fully seam sealed UltraSil Nano™ 15D Nylon fabric has great strength to weight
- Hypalon® roll top closure does not wick moisture
- Reinforced stitching for greater seam strength
