Named for Lai da Tuma, the Romansh name for Lake Toma, the 2,345 m lake below Piz Badus recognized as the source of the Rhine, the Tumas is a men's half-zip sweater knit from 100% virgin merino wool. An insulated chest panel adds core warmth, and contrast color elbow panels bring a heritage detail. A zippered chest pocket keeps small items secure, and a waistband adjuster fine-tunes the fit. Designed for unrestricted movement, it layers under a ski jacket on cold days and works alone for town and travel.

Best for: skiers who want merino comfort with added warmth at the chest.
