Natural Merino Wool by Icebreaker

Icebreaker base layers are made from 100% merino wool – breathable, antibacterial, and incredibly soft against the skin. They provide insulation even when damp, resist odors, and are ideal for long-term use in varying conditions.

Technical Base layers by Mammut

Mammut thermal wear features ergonomic cuts, effective moisture-wicking, and quick-drying properties. Designed for high-intensity activities in cold weather – from alpine sports to everyday urban use.

Bae layers with tailored Fit and Comfort for Women

Both brands offer female-specific fits that ensure a flattering look, full range of motion, and maximum comfort in any condition.

How to care for merino and synthetic thermal base layers?

Wash Merino thermal underwear with detergents designed for wool at 30°. Wash synthetic thermal underwear with detergents designed for functional fabrics. Never use fabric softener, as it affects the fabric's ability to absorb moisture. Dry thermal underwear flat, not hung up, and of course, do not tumble dry.

Pair with a fleece jacket and a hardshell/softshell jacket 

To get the most out of your thermal underwear, wear it with a fleece jacket and a wind/waterproof jacket. The fleece jacket wicks moisture further to the outside, preventing sweat build-up, while the protective layer keeps heat in and protects against the elements.
