Sitka Kelvin Aerolite Optifade Subalpine Jacket

NEW for 2021.  Sitka gear continues to be on top of the specialized hunting gear market by incorporating an innovative new technology from Primaloft into their hunting clothing. Aeorgel infused Primaloft Gold insulation, that they are branding as Aerolite, is the core material this program is built around.  This lightweight, compressible jacket provides incredible warmth with minimal weight and wears comfortably under any outer shell for extra warmth even when wet.  The polyester outer face of the jacket is super thin and will go practially unnoticed under an outer layer but still hold up exceptionally well to the brush and burrs of any hunting scenario if worn alone.

Primaloft has put little balls of air into each fiber of its synthetic material, called the aero gel on those fibers, and what does that does is incorporate air as the greatest insulator.  So, what Primaloft has been able to do is not just have fibers that trap dead air to keep you warm, but they have these little balls of aero gel that add insulation, and resist compression.  Built in conjunction with the US Military in order to replace 650 fill down with something of the same insulation value, hunters can now enjoy an insulation package that is more sustainable, that manages moisture exceptionally well, is incredibly lightweight, and compressible.  At ~30% warmer than down when dry and over 90% warmer when wet because of the air gel fibers, the Sitka Aerolite collection needs to be your insulation solution in cold and wet applications.
