Rab Syncrino Boxers Behind every great mission is a great pair of... pants. The Syncrino Boxers are perfect for hiking, climbing and mountaineering - generally high output mountain activity. They are comfy, super soft and wick away sweat effectively. The Syncrino Boxers are super comfy, lightweight and soft on the skin. They offer fantastic moisture management and odour control to keep you feeling fresh all day long. Rab has constructed these boxers using unique Syncrino 125 fabric - a quick drying merino wool/polyester blend designed to wick away moisture and provide warmth when needed. Merino wool is exceptionally comfortable and soft against the skin. It is recognised in the outdoor industry for its odour control and sweat-wicking properties that help prevent moisture from collecting within the fabric when working up a sweat. Low bulk merrow seams add extra comfort and help prevent rubbing or chafing when worn for extended periods. There's a gusset added in at the crotch
