Sea to Summit - Ultra-Sil® Storage Range Product News

30D Ultra-Sil® is a 30 denier 240T Nylon made from a high-tenacity Cordura® brand yarn. High-tenacity nylon is stronger and more abrasion resistant than standard nylon fibres. We use two different versions of 30D Ultra-Sil®: a Sil/PU and a Sil/Sil version depending upon its purpose and use.

We use Sil/Sil for products where ultralight weight and strength are most important, such as our Ultra-Sil® Day pack, Duffle, Shopping bag and Sling Bag.

We use Sil/PU in products that need to be waterproof, such as our Ultra-Sil® dry day pack, Ultra-Sil® dry sacks, Ultra-Sil® pack liners and many other products.

Ultra-Sil® eVent® Compression Dry Sack

Based on the success of our Compression Dry Sack, we've made a lightweight version from 30D Ultra-Sil®. We retained all the clever functionality of the original compression dry sack, with all the lightweight touches of our Ultra-Sil® technology. The Ultra-Sil® Compression Dry Sack compresses gear to one-third the volume while keeping it dry.
