Created to be the answer when the clouds roll in, the Catalyst Brim Beanie should always be stashed away in your pack. The three-layer laminate construction blocks wind and water, while mapped ear panels retain critical hearing. A flip-away brim blocks the sun when hiking, glassing, or watching the sky, while protecting the field of vision when the precipitation is whipping. Rounded out with a 37.5 fleece, actively managing internal moisture and infrared heat, this beanie is a mid and late-season solution to anything Mother Nature throws at you.
