The zipper is very flimsy and opens out with the slightest of pressure around the waist area and once it has opened out at the waist it is near impossible to open the whole length and zip it back again. Due to this problem I always leave the zipper open.  The jacket is true to size, cut and stiched well. The material is acceptable. I am hoping the vendor will take note of my comment and improve the quality of zippper used.
