- Constructed using high tenacity fibre technologies, weight for weight, CORDURA® fabrics are exceptionally durable.
- Fact is, no matter the application, their fabrics are “best-in-class.” But more importantly, they have to pass their own stringent test criteria before they can earn the CORDURA® brand name. They’re
available in a wide range of weights – from ultra lightweight to heavy weight. and CORDURA® fabrics come in many different constructions and textures. All in all, they’re the fabrics that make strong, long-lasting products even tougher.

- 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.

- 30D high-tenacity Nylon with silicone impregnated on both faces. Silcone impregnation works really well with lightweight fabrics as it improves fabric tear strength, abrasion resistance and packability. Siliconised fabric has a measure of self-healing when punctured. This fabric has a water resistance of 600mm and is used where a product needs to be water-shedding and water resistant but not necessarily waterproof.

- 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.

- 30D high-tenacity Nylon with Silicone impregnated on the outer face and a polyurethane (PU) coating on the inside. It has a water resistance of over 2,000mm. The Silicone outer works really well for water shedding and to create a slippery surface for easy packing. The PU coating on the inside improves the waterhead rating and allows seam sealing tape to bond.

- 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.

Required backpack


Folded backpack is very small, convenient in a pocket or on a belt, useful for going to the grocery store. Maybe next time I would buy a backpack for more. I think a little small. Delivery as always on time.
