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®:
- Cordura® is a special type of nylon yarn used for its strength. These yarns are used in two different product areas:
- In the siliconized Ultra-Sil™ fabrics used in Ultra-Sil™ Dry Sacks, Stuff Sacks, Compression Sacks, Pack Covers, Travelling Light and Travel Essentials products In the foot section of the extremely tough eVent® Quagmire Gaiters.
