Pertex Quantum Nano Ripstop .9oz/yd
We use this version of Pertex Quantum for the shell on our bivy sacks. Slightly heavier than the fabric we use on our sleeping bags, it has increased abrasion resistance and tear strength. The excellent DWR treatment ensures long lasting weather resistance while maintaining excellent breathability.
CORDURA® Silnylon 1.4oz/yd
Our CORDURA® Silnylon is a 30 denier high tenacity nylon ripstop that has been double coated with silicone. This silicone impregnation creates a fabric waterproof to 2 psi, as well as increasing its tear strength. With a finished weight of only 1.4oz/yd this fabric is very strong for its weight, perfect for the floor of our lightweight bivys. The use of the highest quality materials rank the Bristlecone among the best bivys for sale today.
