I've waited until after wearing, washing, and rewearing the leggings before writing my review. I get cold very easily, and was pleased to discover that I could walk the dog in the mid 40s and camp in the mid 50s and feel comfortable in these leggings as my primary layer. They are also very comfortable. I do agree with other reviewers about ordering a size up. I'm normally an XS, however I'm glad that I ordered these in S. The fabric doesn't have much stretch, and I think my standard size would have been an uncomfortable fit.
