So far this jacket has been wonderful and a great find - the bonus being that it's from a Montreal company! The cold winter weather hasn't hit us yet, but so far the jacket has been very warm in -10C with just a cotton long-sleeve shirt underneath. The drawstring clasp isn't very strong, but a simple knot in the elastic cord to kept it clinched works. The only (very minor) downside is that the zipper isn't a two-way zipper, meaning that the bottom can't be opened to offer a bit more flexibility/room to stretch. However, the side hemlines are perfect and very flattering, making it feel and look less like the warm sleeping bag that it is.
