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
- waterproof products (such as the UltraSil Dry Sack are) siliconized 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.
Cordura:
- We use Cordura® brand high strength nylon fabrics as the base for a number of our products before we further strengthen it with a siliconization process. This fabric has an incredible tear strength to weight ratio and will surprise you consistently with what it can handle.
