This there was no issue getting it on slipped right on no problem and zupped up perfect without any issue. UNITL I bent over. I am 143lbs and got a large. I am athletic build and the seam lining the but area just below the bottom of zipper popped. At first I thought I broke the ziper but it was not the zipper at all. It was the seam that broke. Maybe it was just this one part becausr the rest was no issue. Easy to move and I do love it. I will just take it to get fixed lol
