- 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.
Thermoplastic Urethane (TPU):
Thermoplastic Urethane (TPU) is a PVC-free material used in a number of functional areas within Sea to Summit products:
- As an airproof barrier in our Air-Sprung Cell and Self-Inflating mats. Here it is used in a liquid-extruded format the TPU bonds to the face fabric for the highest possible level of reliability.
- As a waterproof barrier in our Accessory Guide Cases and Map Cases; and in several models of our Dry Sacks. Here it is used in a film format, where its superior flexibility (even in cold weather) and waterproofness are key.
- As a waterproof barrier in the Nylon Folding Bucket. This particular film is also food grade ideal for water storage.
- As a transparent window in View Dry Sacks and Travelling Light products allowing you (and TSA inspectors) to see the contents.
- 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.
