The Rip Curl Men's 32 Dawn Patrol Plus Back Zip Wetsuit delivers top of the line performance without plundering your entire savings. E4 neoprene in critical flex zones enhances mobility without significantly increasing cost. E4 neoprene is warmer, lighter, and stretchier than traditional neoprene. The E4 Flash lining uses two layers to transport water to the outside of the suit, allowing it to dry in as little as 30 minutes. The Batwing collar system creates a seal around the collar and zipper to prevent cold water from rushing in when you dive, and Aquaban Plus sealed external seams prevent flushing.
