Why choose it

Merino wool and LIFA® polypropylene work together to regulate temperature across a wide range of conditions. The wool traps warm air while the synthetic inner layer pushes moisture outward, so you avoid that clammy chill after a strenuous climb. ZQ-certified merino ensures ethical sourcing and itch-free comfort, and flatlock seams eliminate irritation when worn under ski pants or hiking shells.

Ideal use cases

• Skiing and snowboarding as a first layer
• Winter hiking, snowshoeing, and mountaineering
• Cold-weather running or cycling
• Everyday warmth under casual trousers

Good to know

These leggings are designed as a snug base layer; choose your usual size for a performance fit or size up for a looser feel.
