Shell: both Base Bags and Modular Over Bags use our proprietary RhinoSkin™. The lightest, yet toughest material available with an excellent DWR finish with a new level of durability.This ripstop fabric is only .9oz sq yd - a little lighter than Pertex Quantum, yet was proven 2-3 times more puncture proof and tear resistant in testing. It's tough enough for military applications; and for any back country use.  Boots-in-the-bag? No problem.
  Insulation: we use ONLY the new Climashield Combat Insulation. Continuous filaments provide superior strength, moisture resistance, durability, thermal efficiency and excellent drape properties.
It is a continuous filament fiber synthetic insulation that has all the properties we were looking for in an insulation. It is very compressable, very thermally efficient, and does not need to be quilted, laminated, or glued to the shell fabric. It also has excellent drape, allowing it to conform naturally around the body. Its continuous filament provides breathability - moisture is released from your body and not trapped, avoiding a clammy feel. You get warmth, even in wet conditions.
Thousands of continuous strands of polyester are spread into a naturally interlocking insulation. This stability means no heavy shell is needed, letting us cut the weight and bulk of your bag dramatically.
Other benefits include:
- highest thermal efficiency possible
- water resistant
- fast drying
- no fiber migration
