The shell material used in all of our clothing and sleeping bags is a proprietary fabric called RhinoSkin™ - an ultralightweight ripstop fabric that is only .9oz sq yd, and comes with a DWR coating. It is a little lighter than Pertex Quantum, yet was proven 2-3 times more puncture proof and tear resistant in testing. Foliage Green on the outside, Camo Green 483 on the inside.
