The Mezzalama Polartec® Alpha® Vest for men is the lightest insulating vest in the collection and well-suited for fast tours. One step ahead: At just 244 grams, this insulating vest is a true lightweight so you can remain fast and efficient on your Speed Tours and competitions such as Grand Course races. The Polartec® Alpha® insulation delivers consistent warmth and is extremely breathable during intense physical activity. The insulation’s open construction method protects you by keeping out cold air reliably yet at the same time allowing excess body heat to escape. The outer fabric is wind- and water-resistant, as well as abrasion-resistant. That means you can wear this as your outer layer on a climb on most days. Stretch inserts ensure you have excellent freedom of movement in any and all directions. The Mezzalama Polartec® Alpha® Vest can be stowed small and compact in its own hood and can find a spot in any pack with its minimal packsize. Two front zip pockets offer space to carry small items such as a phone or snacks. Reflectivity ensures increased visibility at dawn, dusk and in the dark. Mezzalama Polartec® Alpha® Vest – Active insulation at an unbeatable weight.
