I really like it. It's a nice quality vest. My reasons for selling are personal to me and likely won't apply to anyone else. I'm a type 1 diabetic and so when I'm out in the field I need something that will serve not only as a vest for upland hunting but also a carry bag for my medical supplies like insulin and syringes, sugar in the event of hypo episodes, etc. I carry three different types of insulin with me and I've never been on a pump. There is a vest I have my eye on that is a vest and back pack but I need to move this one first.
It's a high quality vest that I really like, but for the reasons above, I need something else. As far as the size, I'm not sure but I can tell you that it fits me well and I'm 6'1 and about 187 lbs. My confirmation email tells me the size is 1SZFM, which probably means a one size fits all. The straps are adjustable.
Let me know and I can take pics if you'd like to see it.
