This suit has a warm pile lined collar that un-zips down when not needed, Cordura seat and knee patches, neoprene cuff covers at wrist and ankles that protect the gaskets, and a lifetime warranty. The customer service I recieved was second to none. This company is run by the Stohquist family and that is who you talk to if you call.
I have used this suit all winter (I paddle at least 5 days a week) and cannot find any faults in its construction. It gave me the confidence to go out in the coldest of winter in all sea conditions. I highly recomend this company and the products they make.
