Trek. Run. Climb. Do it all in the Mar: a highly-breathable, versatile and technical t-shirt built for the mountains. The close-fit, lightweight Merino blend moves easily with your body, delivering optimum performance, whatever the terrain. Improved comfort is delivered through refined details: flatlock seams reduce friction and offset shoulder seams prevent rucksack rub. Eyelet knit back and underarm panels boost active ventilation and help regulate body temperature. A new fabric blend provides excellent shape retention and performance. The highly breathable Merino wool naturally resists odour and is blended with eco-friendly lyocell to boost odour control and keep you feeling fresher on big days out.
