My sons and I fish a lot and wear these in the dirt and grime. We have worn them on the boat as well as scuba diving. They just won't break down. My son's are crazy about them. We have had others but they dry up and crack and don't last. We wash these with wet suit wash by body glove. We also wear the O'neill Epic Wetsuits. We have 5 of them and those last forever too. We are trying out our Hyperflex neoprene Jackets now. We are also new owners of NeoSport xspan pants made of neoprene. Me and the boys are having a lot of fun in your products. Thank you for being such a family positive company. We appreciate the discounts you provide when we make them bigger orders. Thanks Dale.
