I purchased the XS (there isn’t as much choice in jumpers in the women’s section) and it fits comfortably. I’m living in the west of Ireland, and this fleece has kept me warm throughout our wet and cold months! I brought it with me to Scotland the other week and I really felt the difference when I was wearing it on those cooler days. If you can get it at a reduced price, even better! The inner material is top quality, and the outer layer has a lovely texture. The warm neck is especially effective at blocking the wind, with or without a jacket on… overall, I’m very happy with this product and will be buying again from Berghaus 🙌🏻
