Built for skiers who log serious activity, the Smartwool Women's Active Merino Movement Tight is a stretchy, next-to-skin bottom that moves with every stride and turn. Merino blended with a plant-based fiber keeps it cool and quick-drying. It feels more like a favorite legging than a technical base.

Why we like it:

The blend leans on merino paired with Lyocell, a smooth breathable fiber that helps the fabric run cooler than wool alone, which matters when you are working hard.

Features and Functions:

The main body is a four-way stretch knit of merino wool, TENCEL Lyocell, recycled nylon, and elastane, with a Lyocell-rich lining for a soft, cool interior. Flatlock seam construction keeps the seams flat against your skin so nothing chafes on long days, and a drop-in hand pocket gives you a spot for a phone or pass. Reflective elements help you stay seen on early or late outings.

Fit and Sizing:

These sit slim and next to the skin with a high-rise waist that stays put when you bend and reach. If you are between sizes and want compression, size down; for a relaxed feel, take your usual.

Bottom Line:

These are best for aerobic winter days, from touring to trail runs to yoga on a rest day, and they suit anyone who overheats in a heavier base. Wear them solo or under a shell pant.
