The Ultra-Sil Nano pack uses 15D Sil/PU, combined with a thinner roll-top closure and lightweight buckle to create a roll pack that is 30% lighter than the 30D dry back. This makes it perfect for longer treks and backpacking.
**Technical Specifications:**
- Weight 1L: 13g, 2L: 16g, 4L: 19g, 8L: 24g, 13L: 28g, 20L: 36g, 35L: 46g
- Oval base design for easy packing
- Compact and Lighweight
- Fully seam-sealed for water resistance
- Ultra-Sil® Nano has a 1,200mm waterhead
**Proper Use:**
- Any roll-top dry sack must be closed properly to ensure water can’t get in. Begin by folding the Hypalon® strip down first and be sure to have at least three rolls before closing the buckle.
- Avoid contact with sharp objects or subjecting the sack to high abrasion, as this could compromise the waterproof fabric.
- Like all manufacturers of roll-top, fabric dry sacks, Sea to Summit recommends that sensitive electronic devices be ‘double bagged’ (i.e. putting electronics inside one dry sack then placing this inside a second dry sack). For maximum protection, the use of a waterproof hard case should be considered.
- Not intended for situations where dry sack will be submerged under water.
