The Stohlquist aSEA vest has been terrific for use with my Perception Prodigy 12.0 kayak. This vest offers tons of adjustment and is very comfortable for multi-hour trips. The high back flotation foam of the aSEA is invaluable for many of the recreational boats with contoured seat back rests. Having a thick vest pad stuck between you and the seat back is not an overly comfortable situation most of the time; the aSEA takes care of the problem perfectly by putting the flotation foam above the seat back. Durability looks good as well, although time will tell on that one.
