Love the material. I’ve used the full length for a long time and wanted to try the 3/4 with my ski setup. Mostly perfect but I wish that the leg holes were a bit tighter somehow because I find the legs ride up pretty easily when I’m skiing even when I tuck them into my socks. This leaves me a bit chilly at times in one part of my leg. Could be user error, but overall I’m a fan of these base layers.
Decided to get these to replace the REI version. These are much more form fitting. The REI are shapeless and extremely loose fitting. These are much better.
I bought these for fat biking here in Alaska and ended up wearing them all winter. They are the perfect weight and length, I will certainly be buying another pair.
Fits as expected. Comfortable. The ¾ legs are perfect for Downhill Skiing. The wool is NOT itchy.
