Reviews

Pro Flex Trunk

"I purchased 3 of the new Pro Flex trunks from these guys. I have been wearing the trunks for a couple of years now and love them! The fit on the trunks are smaller than the regular trunks and the elastic waistband is very tight. I really don't care for the type of fabric that they use for the Pro Flex trunks. Not sure whether I'm going to return them or not yet. I much prefer the regular trunks"
