I have long legs (35" inseam) and have some trouble finding pants that are long enough. The Medium Long size fits me perfectly. I wasn't sure whether to buy insulated or uninsulated. I opted for the uninsulated, and have been very happy with the choice. I'm using a lightweight layer of long underwear under the pants, and I've been comfortable skiing in temperatures ranging from 3 degrees to 35 degrees. These pants have a nice brushed lining, I think that makes them warmer than anticipated, even though they are uninsulated. Velcro tabs at the waist make it easy to adjust the waist for perfect fit. These are really well made pants. Hard to think of any way to improve them, maybe add a patch pocket to the left leg for a little more storage.
