Exceptionally Warm and Cozy.
This jacket is amazing. It is well insulated to keep you warm in all weather conditions. The fit is big. I originally ordered the women’s size small, it was way too big. I settled on the XS, although, I think I could have gone XXS. I’m 5’4, 115lbs. Love all the pockets. It does well in the rain and beads off the material. I would buy this jacket again.
Go To Belay Parka
Sport cragging, big-walling, bouldering; I rarely leave home without my Nuclei SV. It's my go to belay parka, period. It's even got pockets in the inside to keep your shoes warm between burns.
