    Is it Cold Outside?

    I've worn these about 10 times for lift served snowboarding. I do these under my shell ski pants and that's all I need for single digit riding. They breathe well yet provide enough warmth for anything. Hate how expensive they are because I need about 3 more pair to reduce laundry days but worth every penny. I am 6', 170lbs, 34" inseam, 31" waist and went with the medium.

    Love em! They slide on just right and hug where I want em to without feeling too grabby like others I've used. Keep me very warm without any worry. The one thing I'm not a big fan of are the ankles and how they're heavily seamed at the bottom, instead of just running a small seam to close it.

    These are awesome. Merino wool has become my favorite material for sweaters and socks so I decided to search for Merino wool bottoms and I'm so glad I found these! They're super soft and the stitching seems to be high quality, I'm 5'9", 160, with a 30 inch waist so I'm right in between sizes and went for the medium. They're just a little loser in the crotch than I would like and they're a bit long so I'm replacing them with a small.

    I love high quality wool under layers above all synthetics. The feel and sizing is right on here. I use these in all conditions.
