I love this vest. I purchased the Hurtta one, and while the design and construction were good and it's super rugged, I found the material to be hot and not breathable.It made me sweaty in hot weather and clammy in cold weather. I'd tried on other Euro-type IPO vests and they were always shapeless and billowy and got in the way. I took a chance on this one out of desperation, and I'm *so* glad I did. Depending on your body shape, you might want to size for your hips/butt rather than your chest. It has a two-way zipper so you can zip up from the bottom to give yourself more room if necessary, though. The pockets are great, the material is light and breathable, and while it doesn't feel as tough as the Hurtta one, it has held up remarkably well. Hair doesn't stick and the drawstring at the waist gives it a nice shape and lets it work without billowing over summer tees and winter layers. I ordered my usual men's/unisex size and found it fairly true to size in terms of four-season utility outerwear. If I were *only* wearing it over summer clothes I could have gotten away with sizing down. I'd buy another in a lighter color for wearing in the sun in a heartbeat, if available.
