The Ultra-Sil Dry Day Pack is a waterproof, packable daypack made from siliconized CORDURA® fabric. As well as being ultra-lightweight and foldable, it also resists water and packs into its own tiny stuff sack which comes complete with a carabiner key ring attachment. The seams are double stitched and sealed with high-density PU seam tape and the unique, double hypalon roll-top is non-wicking and creates a good seal. The compression lacing system on the front rounds off this light and functional pack.
- Ultra-Sil 30D siliconised CORDURA® fabric for strength and durability
- Reinforced shoulder straps for increased carrying comfort
- Packs into an attached stuff sack that includes a handy carabiner
- Double stitched seams and fully tape sealed construction
- Elasticized compression lacing system
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.
