O'neill has upgraded the Heat 6/5/4 with much better neoprene this year.
When you are going for a 6/5/4 you want the extra stretch of the new Heat. This wetsuit is really durable and will be in your quiver for a lot of winters to come.
O'Neill Heat Tech Specs:
• Chest Zip with connected hood
• Code Red Zipper with extra large entry
• Single Fluid Weld Seam Seal
• New stretchier neoprene
What we like:
The Heat is the best winter wetsuit for big guys. They have a nice wide opening that makes it much easier than other winter wetsuits for entry and exit.
What we don't like:
When you go up to 6/5/4 for neoprene thickness, your suit is going to be stiff. This wetsuit is light years better than what was available last year, but don't expect it to feel like your 3/2.
Why you want the Heat 6/5/4:
This beast is strong, warm and easy to take on and off for a winter wetsuit.
The Heat is stuffed with all new high-end features and materials. Now built with 100% of our Ultra gooey UltraFlex DS Neoprene, along with our X-Type Firewall in the chest and back, this suit is warmer and more flexible than its predecessor. Also featured is the exterior Fluid Seam Weld, redisigned zipper panel, Covert/Code Red Zipper, new graphics, and easy-in-easy-out usability.
