Description
Description
The Tree Wool Thermal FL Half Zip Longsleeve combines quick-drying lyocell with natural merino wool for a baselayer that performs across a full day on the mountain. This blend regulates temperature efficiently, wicking moisture away from the skin while retaining core warmth during high-output climbs and exposed descents alike. The merino content brings genuine odor resistance to the table, making this longsleeve a reliable choice for multi-day ski touring, winter mountaineering, and backcountry missions where washing options are limited.
A waffle-knit structure increases surface area for superior moisture transport and heat retention, keeping you warm without overheating on demanding ascents. Seamless side construction eliminates friction points, so it sits comfortably under a shell or softshell for hours without chafing. The stand-up collar adds welcome warmth around the neck on exposed ridgelines and blustery days, while the long half-zip offers quick, easy on-off access and instant ventilation the moment things heat up. Finished with an athletic fit for a close, non-bulky layering profile and weighing just 220g, it's a lightweight thermal built to work hard and pack small.
