It is built from double weave Matrix softshell fabric - a light, durable, quick-drying material, with outstanding moisture management properties, generous stretch and easy packability. Articulated knees and a diamond crotch gusset make best use of the inherent flexibility for ease of movement. A leg zip with internal gusset delivers extra space and ventilation when you need it and the lower hem loops enable you to attach the pant securely to your boots.
