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® 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.

Frequently Asked questions
Able to travel as checked baggage?
No. Baggage handling machinery (especially in many overseas locations) will wear / tear holes in the fabric.
Capable of carrying heavy weights?
The seams and materials will support a surprising amount of weight. But – the grab handles are not padded and the bag has no structure, so we would not suggest carrying anything above 18 lbs / 8 kg for anything more than a short duration.
No. It is only water-resistant. Even though the pack is made of a waterproof material, water can enter through the seams (which are not sealed) and the zipper. A few minutes of light rain would not be a problem, but a downpour would result in the contents of the pack getting wet.
