Seeking advice on what to look for in PFD for male & female. We have folding kayaks and our past kayaking we haven't needed a PFD. Would like some info on style/brand/etc and what is ideal for touring. At the moment I'm looking @ a Stohlquist Motion or the Extrasport Retroglide Sabre - without access to a 'kayak outlet' here - it is a case of purchasing via the net, so I'd prefer to have some advice/comment.
