Description
Designed with ultralight backpacking in mind the Ultra-Sil Nano™ Dry Sack is made from lightweight 15D siliconized Nylon. With the use of featherweight 15D fabric, these are perfect for use inside your pack to keep gear organized and dry. Using a hypalon roll-top closure that doesn't wick moisture, an oval base for easy packing, these are fully seam sealed for water resistance. Ideal for backpacking, climbing, cycle touring and modular packing where lightweight and low bulk is key.

Frequently Asked questions
Suitable for paddle sports?
No. Featherweight fabrics are not appropriate for the sharp or abrasive elements in watersports. We recommend Lightweight Dry Sacks for general paddle use.
Waterproof?
The body of the dry sack is more than adequately waterproof (1200+ mm hydrostatic head) for the intended use (storage inside a backpack or duffle).
Worth their weight and cost?
Once you've experienced modular packing with ultralight, easy to pack, translucent dry bags, you’ll wonder how you ever lived without them.
