Proton LT Hooded Insulated Jacket - Women's by Arc'teryx
Noticing that most "breathable" insulated jackets don't actually breathe that well during fast-paced activity, Arc'teryx designed the Proton LT Hooded Insulated Jacket for high-output alpine missions where thermoregulation is key to completing your lofty objectives. Instead of being merely breathable, the Proton LT's face fabric and insulation are air permeable, meaning the jacket allows rapid air exchange without relying on built-up pressure to expel condensed perspiration along the inside of the shell. Ultimately, this means you'll stay pleasantly dry from the inside-out. Additionally, Arc'teryx gave the Proton a climbing-specific cut with a slim fit that reduces needless bulk while articulated arms and gusseted elbows enhance mobility.
