I've had a SAS Mk5 for a few years now and I'd replace it with another Sundridge suit in a heartbeat, Fladden suits are one of the best 'flotation' suits but not as comfortable and don't have the handwarmer pockets  :HPY2:

Be forwarned wipe your hands on a rag not in your handwarmer pockets lol, the smell can empty a pier after a month.
