DUI FLX Extreme Dry Suit

$3,465.00$5,205.00 Plus Tax

DUI’s 2016 best selling drysuit, the FLX Extreme, is perfect for advanced technical divers and the most popular option for exploration divers. We set out on a mission to develop the most comfortable and flexible drysuit to provide maximum protection for technically demanding conditions. In that mission we discovered the perfect combination of materials and craftsmanship. Using trilaminate fabric made of a Polyester inner and outer layer with the butyl-rubber interior slightly thicker than the TLS350 – adding additional puncture resistance. We then add Cordura® overlays on the legs for increased durability though soft to the touch just like your favorite pair of jeans.
