"Heat 3/2 has always been my tried and true wetsuit for SoCal waters. My last one is still wearable after 10 years, but it was time for a new one! So comfortable, warm and flexible. Plus, I like how the key pocket is located outside so I can quickly grab something from car if I need without having to unzip."
"Water temperature 62, stayed nice and warm. I'm 5'11 large fit perfect even over my beer bump."
"Super warm and flexible. very comfy wetsuit. Nice firewall."
"Great Wetsuit, love it"
"Love the suit. Snug fit but super comfortable. Nicest one I have ever owned."
"I have yet to try my 3/2 Heat"
"As compared to other suits, you get the warmth of a 4/3 with the flexibility of a 3/2. Supper comfortable in 60 degree water. Be aware, they run small. I’m 160 lbs/ 5’ 10” and mine is an XL."
"Have always been a Ripcurl f-bomb guy (30 years) but wore this suit for the first time today and I couldn't believe how light, stretchy and warm this suit is. Absolutely the best wetsuit I have ever worn."
"Works well. Easy to get in and off. Me happy"
"At 64 years old and still surfing a lot, this is the best wetsuit I've ever had. The Techno Butter material stretches so that I feel like I'm surfing in trunks (compared to my other wetsuits). Worth every penny if you're used to paying less or looking for less resistance."
