While initially hesitant about purchasing a pair for that very reason ... I'll have to say that my Simms Guide Models have far outlasted any pair of neoprenes that I've ever had.

Most others I've heard mixed reviews on in the boat ... make a point of asking about other products out there

Warranty service??? Never had to use it ... they were so hammered before they ever sprung a leak that I just retired them to boat use only (still fine for hopping in and out of the boat). Still using them today ... have a new pair for wade fishing now.

They are spendy, but I've always been a believer in the fact that you get what you pay for
