93% Merino wool, 7% spandex
Here's what other sites are saying:
If you spend as much time in ski boots as street shoes, you can appreciate the shortened Stoic Women's Merino -Length Bottom. Primarily made of odor-controlling, highly breathable natural merino wool, Stoic added spandex to promote comfort and mobility during high-octane activity. The Y-Elastic stitch technique makes a smooth, extremely comfortable seam at the waist and flat-stitch seams reduce rubbing.
