Stefan Says:
"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. "

This has got to be about the 8th ONeill Heat I've bought through the years. I love them so why change, both the 3/2 and 4/3. This is the first time I've purchased from Cleanline. My order was shipped really quickly, packaging was good, the wetsuit was perfect and they put in a nice note and bar of wax! My 3/2 is now getting a little ragged so I'll be getting the next one from Cleanline soon. Well done folks!

Do not buy this wetsuit. I bought it because they stopped making the Psycho Freak, then they Stopped Making the Psycho Tech in My size. Last year I bought a Hyper Freak, that tore in multiple places, poor quality. Then This year I bought the Heat because it's the only Back Zip. Took it out surfing this morning, and constant spinal shots of cold water down the back. I wouldn't pay $100 for this wetsuit. Total garbage. O'Neil used to be the best, now I fear they are the worst.

I love how cleanline surf sent me with thank you card, candies, and a free surfboard wax in the package! This wetsuit is wonderful and quality.

Awesome suit
I will be honest 2xl shorts are hard to come by particularly in Canada, so I was really happy to have a suit that fits. Excellent range of motion and more than warm enough to surf the east & west coast of Vancouver island. Surfing river mouths in February in a 4/3 and toasty. Thanks to cleanliness for getting it to me in short order. Put it to work right away

Very Good
This is my second O'Neill wetsuit. The first was exactly what I needed for SoCal winter. The Techno Butter is especially stretchy without giving up warmth. I know this one will be just as good as we head into late fall and winter conditions.
