Kinetic Alpine 2.0 Pants WmnsConstructed from three layer Proflex Kinetic 2. 0 fabric, it uses an internal PU membrane, sandwiched between a durable nylon woven outer and a soft, fast wicking inner. This delivers outstanding stretch and breathability for fast paced scrambles with a slim, athletic cut and articulated knees for easy movement. The adjustable elasticated waist uses a secure silicon grip and the ankles and hem use heavier woven reinforcements to increase durability.
