The Devold Explorer vest is designed for comfort and maximum warmth while being as light as possible. It is made of merino fleece, which is ideal for high altitudes where temperatures can change in an instant. The super-soft, brushed inner layer made of 100% merino wool forms air pockets around the body, providing excellent insulation. For the outer layer, we use expedition wool to wick moisture away from the body as efficiently as possible. The Explorer series is designed for longer hikes, with good mobility being an important aspect of the product design. This unique merino wool blend provides greater comfort when hiking and at base camp.
