I purchased these for some very mild winter sports / outings. Mainly snow tubing and sledding. I ordered a size XL and wear a size 14 pant. The pros are that they keep me warm and dry, feel really well made, and are easy to move in. The one negative about these are the snap buttons. They pop open pretty much any time I get up from a seated position or twist or move my body. The pants are not tight, they fit well, and I am convinced at this point that the buttons aren't very sturdy. Overall still good pants.
