Technical Features

30D ULTRA-SIL - An incredibly lightweight yet durable fabric used in a large number of Sea to Summit products. This 30 denier Nylon is made with CORDURA® yarns for strength, woven into a ripstop pattern. Two versions of the fabric are used:

• Water-resistant products (such as the Ultra-Sil Stuff Sacks) are siliconized on both sides for ultimate packability
  

Features

• Compress soft contents down by as much as two thirds
  
• Side-release buckle compression straps for fast and easy access
  
• Water-resistant, bluesign® APPROVED Ultra-Sil 30D Nylon fabric with a non-PFC DWR finish
  
• WATERPROOF? The fabric is waterproof enough for storage inside a pack, but the seams are not tape sealed, and the top does not utilize a roll-top closure. So - water resistant rather than waterproof
• Three ultralight compression straps with two ladderlock and one side-release buckles allows easy access and reduces weight
  
• Attached tip-top lid prevents straps tangling
