Weird Fit

I've used it once or twice and have initial impressions
5` 11"
155 lbs

This was one of the strangest North Face pieces that I have tried. I was really excited about using it on a really cold ski day, but I on the morning that I was going skiing, I realized that these knickers have no way to adjust the waist! I have like a 30" waist and I tried the M knicker which should accomodate a 31" waist and it was wayyyy bigger than me. There is no way to sinch or pull it tight, so if it does not fit you perfectly out of the box, then unfortunately it never will. Serious let down as I had to ski the whole day with this piece sagging below my butt.

Good comment, very helpful. I was thinking as to how they secured the waist. I guess they depend on the shell to hold this piece in place. The other shortcoming is that the side zippers do not come off. They have done half the job, maybe in the future.

Great for cold days and nights skiing

I've used it several times
Runs large
Size Bought

I used these on a few super cold days here in Utah anmd just about every time I go night skiing. They work great and really add some warmth to my bibs. They do run a little big. I am a medium in just about everything and the medium was a little bog around the waist. Overall, I would definitely recommend these if you get cold.
