I am interested in buying a Flex Extreme drysuit this year. I tried a number of suits at one of your Dog Day demos last year and one future I liked was the Quick Zip design. It made it a lot easier for me to start the zipper. My LDS tells me that it is not available on the Flex Extreme. Is this true? I would expect your newest suit would incorporate your newer zipper design as an option (if not standard).
