I have lifeline jackets that arent full race, real comfortable to wear, and I cant belive how quickly they right you if you dive in and just completely relax. even if you try to go face down they flip you over into a perfect vertical position with feet forward at about a 45 degree angle, head back. They are nice with good pockets, zip up nice, real secure, and you feel much safer with them on, and they work to keep you breathing at a proper angle great! I think most higher end jackets would be comperable. Lets see what others say, mine are getting old, and the colors match my cat not my advantage.
