Rabs Kinetic Alpine 2.0 Pant is the perfect pull-on, leave-on piece for fast-paced summer alpinists.As part of Rabs Ascent range, it features Stretch Nylon Woven Proflex with carefully zoned panels that are designed to cope with the increased abrasion and exposure of technical ascents without critically inflating the weight. A slim, tailored cut with articulated knees provides far better freedom of movement than a traditional waterproof pant. The flat semi-elasticated waistband is comfortable with a harness, a plus a pair of zipped hem gussets enables you to expand the cuff for large mountaineering boots. Stripped back but high functioning, this is the ultimate in fast, light, free-moving protection for committed alpine adventurers. Proflex Fabric Feels like a softshell, protects like a hardshell. Proflex is our own waterproof membrane offering outstanding comfort at high intensities and in wild weather. Developed to offer stretch and exceptional breathability, the Proflex PU membrane has natural elasticity. It works in harmony with recycled knitted or woven fabrics to maintain this stretch and achieve a lightweight, soft, and flexible 3-layer waterproof fabric. The inner fabrics of Proflex laminates have excellent wicking properties. They work with the hydrophilic membrane to accelerate the process of moisture movement away from the body and out through the system. A DWR treatment on the face fabric keeps the membrane functioning at its best.
