Proton FL Hoody Men

Climbing in durable, lightweight, mid-layer or stand-alone, the versatile Proton FL's breathable thermal protection provides comfort across a range of temperature and power levels. Octa® Loft knitted insulation provides warmth, resists packing and allows airflow to regulate comfort. Abrasion-resistant Fortius™ Air 20 fabric stretches, resists wind and allows temperature-regulating airflow. A zippered chest pocket secures a radio, articulation aids mobility, and the low-profile insulated hood fits comfortably under your helmet.

Updated with improved Octa® Loft knit insulation and stretchy size chest pocket.
