Product Info

Staff Says Cleanline Staff 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. "

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.

I've been wearing this wetsuit for almost six years and it has never let me down

Excellent item.

Following the wetsuit from location to location was great.

The wetsuit was delivered smoothly to the front door thousands of miles away from its origin. Tried on, fit perfect. Excellent service. Hopefully will be able to come stateside one day and try the surf near you guys. Many thanks and best regards Gareth.
