What Our Gearhead® Experts Are Saying:“I love the Albula IN Vest as a low-bulk insulator for hikes and cool-weather layering. It’s surprisingly warm for how light it is, and the fact that it’s made with recycled materials makes me feel even better about bringing it along on every trip.”When chilly morning starts demand warmth without the weight, we zip into the Albula IN Vest. Designed by Mammut with a sustainability-first approach, this lightweight layer is filled with Thermore® Ecodown—insulation made from post-consumer PET bottles. That means it keeps us warm while keeping waste out of landfills. Whether we’re layering it over a baselayer on crisp hikes or using it to boost our midlayer system under a shell, the Albula provides adaptable warmth in a sleek, eco-conscious design. The outer material is made entirely from recycled polyester and finished with a PFC-free DWR treatment, giving us weather resistance for shoulder-season hikes or camp mornings. A tall, snug collar seals out drafts while zippered hand pockets keep our fingers warm or hold onto the small essentials. With a trim fit and low-profile elastic hem, this vest layers smoothly under jackets or stands alone as a simple solution for active insulation.
