Engineered with Moonstretch fabric for its windproof, highly stashable nature, the Maloja Men's PeiderM. Vest adds extra warmth and protection from blustery days and cool conditions on the trail. Its lightweight design easily folds into your hydration pack for instantly deployable protection when the weather suddenly moves in. The vest's DWR finish sheds light showers and outside moisture from soaking through. Mesh inserts enhance ventilation for a pleasantly dry feel when you're working up a sweat. Other key features include bi stretch movement for full mobility, as well as a star printed, semi auto lock zipper that won't flap in the breeze.
