Arc'Teryx Proton LT Jacket Men's

The Mens ArcTeryx Proton LT Jacket is an insulated jacket for delivering lightweight warmth while on the mountain. The Proton LT Jacket 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. In addition to being extremely air permeable, the Fortius™ Air 20 face fabric has unrivaled hardwearing durability, over 60 times more durable in abrasion tests than the industry standard. Coreloft™ Compact 80 synthetic insulation maintains excellent stretch recovery. The No Slip Zip™ keeps the main zipper from self-opening. Put it on, leave it on and stay focused on the activity. Designed to perform both as a soft-shell outer layer and as a mid-layer under a waterproof shell, the Arc'Teryx Proton LT Jacket is an all-around, versatile jacket that balances warmth and airflow.
