Your ultralight, ultra-mobile alpine shell is only as good as the layers underneath it. Don't get held back by uncomfortable and restricting midlayers--grab the Rab Nucleus Hooded Fleece Jacket and get stretchy performance and trusted warmth for all of your cold-weather pursuits. Thermic stretch mid-weight fleece offers you comfortable warmth and unencumbered movement, so you can climb on into the fall then suit up for backcountry touring trips in the winter. The oval-grid fleece backing allows the Nucleus to wick moisture and release heat more effectively, giving you reliable performance during more high-output pursuits. The under-helmet hood is there when you need it to be on windy summits and cold resort days, so even your head can enjoy the warmth of this versatile fleece.
