Wear an Icebreaker next time you’re out in the backcountry.

Layering is essential when you’re outdoors, and there are two basic types of fabrics that work best underneath: synthetics and natural fibers.

One of the best natural fibers is merino wool. This super-fast drying, lightweight material feels amazing.

New wool weaving technologies allow the wool to be non-itchy and unusually soft. It naturally secretes lanolin oil which prevents odor from building up.

It also wicks moisture away from your skin, keeping you dry. Even when wet, merino wool will continue to insulate and keep you warm.

The Icebreaker Bodyfit SS ATLAS is their lightest, slim-fit wool layer. It clings tightly to the skin yet continually wicks away moisture from the body. Its underarms are gusseted to avoid chaffing.

Wool has never felt this good.
