Tips

Merino wool is naturally self-cleaning; air out your leggings between wears to extend time between washes. When washing, use a gentle detergent and avoid fabric softeners, which can coat the fibers and reduce performance. Pair with an Icebreaker 200 Oasis top for a complete base layer system.
