Afterpay – How it works
The Ultra-Sil Compression Sack allows you to compress the volume of your compressible gear without significantly adding weight. It features bluesign®-approved ultra-lightweight yet tough Ultra-Sil 30D nylon with a non-PFC durable water repellent finish, a drawstring closure with attached lid and compression straps for even compression. Ideal to compress clothing or bulky soft items for more space in your pack or bag.
  • Ultra-lightweight, bluesign®-approved Ultra-Sil 30D Nylon main body fabric with a PFC-free DWR finish
  • Compress soft contents down by as much as two thirds
  • Drawstring closure with compression straps
  • Side-release buckle compression straps for fast and easy access
  • 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
  • The fabric is waterproof enough for storage inside a pack, but the seams are not tape sealed, and the top does not utilise a roll-top closure. So - water resistant rather than waterproof

Material
30D Ultra-Sil nylon with non-PFC DWR finish, 2000mm waterhead

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 siliconised on both sides for ultimate packability
  • Waterproof products (such as the Ultra-Sil Dry Sack are) siliconised on the outside and PU-coated on the inside to allow seam taping.
  • Both versions have a hydrostatic head greater than 2000mm, which makes them more than adequately waterproof for the types of environments they are intended for.
