A versatile, quick-drying, lightweight baselayer shirt in wool/synthetic mix. This technical base layer shirt is made for all-year mountaineering but works perfectly for general outdoor activities ranging from trekking to ski touring. We use a premium equaliser/merino fabric in this product because of the wool&&';;s natural thermal regulation and anti odor properties, the durability, low weight, and moisture-wicking performances of polyester. The low weight (135g/m2) fabric is made with 47% Merino wool, 53% recycled polyester, the best of both worlds and gives superb hand feel. The shirt has a technical fit.
