The Marmot Men's Isotherm Vest is an insulated vest for core warmth in the backcountry. Slip it on over a baselayer on mild days and your heart will stay toasty warm, whether you're spring skiing, exploring the backcountry or climbing. No sleeves to get in your way, it'll go over short or long sleeves, while going under hardshells in wet weather. Versatile and packable, the Polartec® Alpha insulation resists moisture and warms in the cold.
