Arc'teryx Proton Pant - Women's

The Arc'teryx Proton Pant is a light, breathable, insulated, and weather-resistant midlayer for touring, climbing, hiking, and more. Abrasion-resistant Fortius Air 50 fabric stretches, resists wind, and allows temperature-regulating airflow, a durable water repellent (DWR) finish sheds light precipitation. The Proton bottom uses Octa Loft knit insulation, which provides warmth, resists packing out, and is air-permeable, to ensure comfort. Durable enough for climbing yet light enough for the trail, the Proton Pant offers thermal protection and comfort across a range of temperatures and output levels.
