Designed for all types of extremes!  

The Protect Fiber bag is custom-built for extreme conditions and optimised for a quality night's sleep in the coldest temperatures. It has a central zipper with an insulated covering that protects you from cold bridges and enhances climate comfort. An insulation chamber around the hood opening protects your face from icy wind chills, giving an additional level of defence from the elements. The inside lining is made from 100% recycled polyester, and the outside has a PFC-free DWR treatment, meaning that even in heavy dews, mist and rain, you’ll stay dry and warm. 

For an extremely good night's sleep, in extreme conditions, the protect fiber bag is the one you grab as you head out the door for your next adventure!
