Dynafit Elevation Polartec Alpha Jacket Men's

You might be completely warmed up before you reach higher altitudes, but running along mountainous ridges can still get cold. The Dynafit Men's Elevation Polartec Alpha Jacket keeps you warm when you're up there, and it excels in breathability to keep you comfortable when you're warming up in lower elevations. Unlike standard breathable garments, Polartec Alpha's air permeable insulation starts to breathe the moment you put it on instead of when you start sweating. Air permeable garments extend your comfort when you're active in the alpine.
