I had a V8 that the foam was separating on and needed a new PFD for kayaking. Just about everything makes me break out in hives. My local store had gotten this in and I decided to give it a try after reading other reviews.
It is minimalist, 6 straps. You have to pull it over your head to put it on. It will work for men or women, I am a 56 year old woman. It is light, comfortable, and it did not make me break out. Neither did it ride up so that I had PFD in my chin.
The drawbacks so far! I need to play with the shoulder strap adjustment. The shoulders did rub my neck a little, not badly. After the first use, the front did "pinch" my chest somewhat so I have to figure out how to get it a little lower. That would be the difference between an 8 and a 10.
