There's no need to shiver through summertime surf sessions when you have the O'Neill Heat 3Q Zip 32 Men's Full Wetsuit ready to go. It's built to keep you warm during long days in mild water temperatures, with an UltraFlex DS neoprene body and insulating UltraFlex Firewall chest and back panels. All the seams are decked out with a single Fluid weld for extreme waterproofing and flexibility, and there are also strategic seamless paddle zones and a seamless LSD lumbar design for comfort and a ridiculous range of motion. If that's not enough, O'Neill also hooked the Heat up with Krypto knee pads for flexibility and toughness, threw in an extra long back zipper for easy entry and exit, and built in an external key pocket so you don't get stranded beachside after losing your key when you get rolled. There are worse places to get stuck, though.
