Breathable, soft on the skin and stretchy, with a gusset at the crotch for excellent mobility, the Syncrino Leggings are the perfect first layer for climbing mountains in cold temperatures. Odour resistant and fast drying they&';re ideal for multiday adventures. Our lightweight Syncrino 125 fabric is made from a blend of Merino wool and 32% recycled synthetic fibres. Merino wool is ideal for cold weather baselayers. it&';s ability to absorb water makes it excellent at wicking sweat away from the skin, maintaining comfort, and regulating body temperature. It&';s also a great insulator, even when it&';s wet, although it can take a while to dry. The man-made synthetic fibres are strong, durable, lightweight, and hold their shape well. They can also dry extremely quickly. By blending these yarns, we have created a quick-drying, fast-wicking, insulating, and durable material that&';s ideal for mountain baselayers.
