The Ultra-Sil Dry Bag won the sought-after Backpacker Editors' Choice award in 2006 and remains the ideal dry bag for backpacking and travel. Made with lightweight, waterproof bluesign approved 30D Ultra-Sil fabric featuring CORDURA yarns, it's the perfect choice to organize your gear inside your backpack or duffle like a pro.

An excellent choice for lightweight backpacking, cycle touring and travel.

Technical Features:

• 30D Ultra-Sil
  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.

• Cordura
  Cordura is a special type of nylon yarn used for its strength. These yarns form the heart of the siliconized Ultra-Sil™ fabric, used in:
  • Storage products: Ultra-Sil™ Dry Bags, Ultra-Sil™ Stuff Sacks, Ultra-Sil™ Compression Sacks
  • Camping/Backpacking Accessories: Ultra-Sil™ Pack Covers, Ultra-Sil™ Folding Bucket and Kitchen Sink

  • Travel Essentials: Ultra-Sil™ Daypack, Ultra-Sil™ Dry Daypack, Ultra-Sil™ Shopping Bag
• Non-PFAS
  Sea to Summit sleeping bag fabrics and insulation are made without PFAS compounds. The non-PFAS DWR finish on the shell helps prevent the insulation from becoming damp if the bag comes into contact with moisture, such as tent wall condensation.Ultra-Dry Down is a non-PFAS hydrophobic treatment that absorbs less moisture and dries more quickly. It does not affect the 'breathability' or the lifespan of the down and lasts through at least 20 washings. The down used in our sleeping bags is responsibly sourced.Sea to Summit Dry Bags, Stuff Sacks and Compression Bags use a non-PFAS Durable Water Repellent finish to help shed water. Big River bags use a non-PFAS PU coating.
