I really really wanted to like these - I asked for them for Christmas from my bf but did not get them... I wanted them so bad I even ordered them myself on Christmas evening.
I am 5'9" 135 lbs, regular sized. I ordered the medium. It was too short, too tight around my knees (what?) and loose around the waistband. It made me wonder, who WOULD fit these? If I bent down (to ride) half my butt was exposed. I know they look really cool, but practically I don't mind if snowpants come up higher to save me from the snow-in-butt phenomena.
Points off for fit and velcro pockets (tend to weather badly and doesn't provide a waterproof seal) Sigh. Still looking and will try some other types.
