High off the deck on Warbonnet Peak in the immaculate Wind River Mountains, the naming of the range quickly makes sense. Our windproof and stretchy Lightweight R4 Jacket protects and warms with a Polartec Windbloc laminate sandwiched between a low-nap polyester microfleece face and a high/low grid polyester interior. Unlaminated R1 underarm panels 60 recycled polyester enhance breathability and mobility, while a neck gasket seals out the elements. Seamless shoulders allow pack-wearing comfort. With three external pockets the handwarmer pockets stay clear of your harness, two internal drop-in pockets and a drawcord hem. Recyclable through the Common Threads Recycling Program.
