Arc’teryx Proton LT jacket

Women’s 2021 model. Bought last Fall and only worn a handful of times. Great jacket and super warm but looking to size down as it fits a little snug under my ski shell. My loss your gain! The Proton LT Hoody is equipped with a breathable insulation package to manage the dynamic needs of mountain pursuits and perform as a self-regulating mid layer for a variety of high output activities. Breathable insulation means excess heat and moisture can pass through the combination of air permeable fabrics and insulation.
