Arc'teryx Proton LT Hooded Insulated Jacket Women's

Noticing that most breathable insulated jackets don't actually breathe that well during fast paced activity, Arc'teryx designed the Women's Proton LT Hooded Insulated Jacket for high octane alpine missions where thermoregulation is key to completing your lofty objectives. Instead of being merely breathable, the Proton LT is air permeable, meaning it 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, especially on those hard climbing objectives and long slogs en route to the summit. The Proton LT is a great piece for cool transitional seasons, courtesy of its Coreloft Continuous insulation. This synthetic insulation won't succumb to soaking wet conditions, meaning it won't clump together when wet and lose its lofting ability like down. The shell's DWR treatment beads off passing showers and snow, keeping you dry through light precipitation. For greater weather protection, layer it underneath your waterproof hardshell as a toasty mid layer for backcountry skiing and alpine objectives in severe weather. Other key features for sealing out the elements include an adjustable hem, stretch knit cuffs, storm flaps under the main zipper, and helmet compatible hood with adjustable drawcords.
