I had a pair of size 4 Sunice ski pants for a few years and decided that I needed to go up one size. I was disappointed that there was not much of a difference in size. I'm not a big person, 5'6" and 125lbs. Decided not to return them because I would have to pay for shipping and I would loose the duty that I had to pay as well. I was planning on wearing them this ski season but broke my left wrist so there goes skiing for this year.
