The Ultra-Sil™ Dry Sack won the sought-after Backpacker Editors' Choice award in 2006 and is still the ideal dry sack for backpacking and travel. Made with lightweight, waterproof 30D Ultra-Sil™ fabric featuring CORDURA® yarns it's the perfect choice for modular packing to organize your gear inside your backpack or duffle like a pro. The semi-translucent fabric means that it’s easy to see what’s in each dry bag, and if you're really organized you'll make use of multiple color options to find things even easier. Other features include a non-wicking hypalon roll-top closure, a round base for ease of packing and taped seams to keep moisture out. An excellent choice for lightweight backpacking, cycle touring and travel.

Are Ultra-Sil Dry Sacks....?

  • Suitable for paddle sports?  No. Featherweight fabrics are not appropriate for the sharp or abrasive elements in watersports.
  • Waterproof?  The fabric is more than adequately waterproof (2000+ mm hydrostatic head) for the intended use (storage inside a backpack or duffle).
  • Worth their weight and cost?  Once you have experienced modular packing with ultralight, easy to pack, translucent dry bags, you’ll wonder how you ever lived without them.
