Our First Ascent line is cut closer to the body for a great, active fit with no bunching or binding. The nearer to the body the layer is, the closer the fit will be. It is built as a complete system. All pieces-outerwear, insulating layers and baselayer-are cut so the body and sleeve lengths of each successive layer are slightly longer than the one underneath.
