Blending the best of wool and fleece, Polartec’s Power Wool fabric was the perfect choice for Mammut’s Trovat Pro ML Men’s Jacket. A breathable and moisture-wicking midlayer (hence “ML”), the Trovat can also be worn on its lonesome when you’re out for a fall hike, plugging in gear on a chilly fall day, or chasing some backcountry pow. Thumbholes keep the sleeves in place, flatlock seams prevent irritation under pack straps and harnesses, and the soft chin guard makes sure your skin doesn’t get irritated when you duck your head against the wind.
