The smaller sizes (2, 4 & 8 Liter) of the Ultra-Sil Dry Sacks are bundled together in a neat package of three. The Ultra-Sil Dry Sack won the sought-after Backpacker Editors' Choice award in 2006 and remains the ideal dry sack for backpacking and travel. Made with lightweight, waterproof 30D Ultra-Sil fabric featuring CORDURA® yarns, it's the perfect choice to organize your gear inside your backpack or duffle like a pro. The semi-translucent fabric makes it’s easy to see what’s in each dry bag. An excellent choice for lightweight backpacking, cycle touring and travel.
An incredibly lightweight yet durable fabric used in a large number of Sea to Summit products. The 30 denier bluesign Approved nylon is made with CORDURA® yarns for strength. A Non-PFC DWR finish on the outer face helps to shed water.
The inside is polyurethane-coated – in dry bags, the seams are seam-taped.
The hydrostatic head is greater than 2000mm – more than adequately waterproof for the types of environments Ultra-Sil dry bags, stuff sacks and compression sacks are intended for.

Frequently Asked questions
Is this dry bag suitable for paddle sports?
No. Featherweight fabrics are not appropriate for the sharp or abrasive elements in water sports. We recommend Lightweight Dry Backs for general paddle use.
Is this dry bag waterproof?
The body of the dry bag is waterproof enough (2000+ mm hydrostatic head) for use as storage inside a backpack or duffle. However, for water sports or on its own, we recommend dry bags with higher hydrostatic head ratings.
Is this dry bag worth the 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.
