NWT ADIDAS TERREX MYSHELTER WINDWEAVE JACKET Similar To Arc Proton FL W/octayarn. Very similar design and insulation as the Arc’teryx Proton FL (Lightweight) Hoody. They both share the extremely cozy octayarn insulation which is incredibly breathable, lightweight and retains a good amount of warmth for the weight. Excellent technical piece, dare I say better quality then Arc’teryx’s offering.
