"The Heat has been going strong since the ‘80s and has built a cult following around it’s simple, yet practical and rugged design. This year, it has been seriously improved with O’Neill’s top, most flexible rubber, Techno Butter 3, making this the most flexible back zip for the money. The seams are welded, there’s an internal liner, a great zipper and the Heat is also available in some of the more rare O’Neill sizes like 4XL and XXLS. Overall, for a dependable back zip, you can’t beat the Heat. "
The O'Neill Heat 4/3 Back Zip Wetsuit is stuffed with high-end features and materials. It's built with TechnoButter 3 Neoprene, TechnoButter Firewall heat-retaining lining in the chest and back making this suit warmer and more flexible than ever before. The Heat also includes exterior Fluid Seam Weld, a redesigned 3Q length zipper panel and easy-in-easy-out usability.
