Heading up to the pass, moving fast but taking a break is out of the question. The Mens Mountain Pass Dynamic Jacket is just as ambitious as you are with the reverse side of the fleece having an innovative waffle structure with several key attributes. Air can circulate better between the fabric and the skin, so the jacket is warmer and the internal microclimate is consistently good. Jack Wolfskin have also incorporated high–stretch inserts to maximise freedom of movement. The Mountain Pass is such a comfortable fit that you will hardly notice you are wearing it.
