Matt Says:

"Have you picked up a suit from Billabong recently? They have been stepping up their game these last few years and suddenly they’ve released what I would say is the best 6mm wetsuit on the market. This thing is SUPER stretchy for it’s thickness, and based on the warmth of the 5/4 version of this suit (which I’ve worn) I would say it’s one of the warmest 6mm suits. If you need a REALLY warm wetsuit without sacrificing any stretch this is the one."


The Billabong Furnace Carbon Ultra Hooded Chest Zip is a top shelf wetsuit and that is now warmer and lighter than ever. Updated with the newest technology for the 2018/19 season, the pinnacle of wetsuits is now made with 300% stretch smart foam, adding more heat and flexibility. Made from upcycled car tires, the eco-conscious smart foam is topped with a no soak external jersey, holding 30% less water, radically reducing both weight and wind chill. On the inside, Billabong's warmest carbon fiber lining traps body heat, adding to the suit’s thermal retention without adding weight. The incredibly efficient and ultra warm suit is topped with a Drymax entry system to keep water out and heat in. The ultra lightweight and high stretch material combined with anatomic strategically shaped seams for the ultimate performance wetsuit.

Billabong Furnace Carbon Ultra 6/5 Hooded Chest Zip Wetsuit Stoked on the new neoprene fellas Review by Barnacle Ben Barnacle Ben
Super stoked on the new rubber. Solid suit for the price for sure. Cleanline surfshop has done it again. Super speedy delivery with no hickups. Super stellar service as always. You guys are so rad man. Thanks for the gear and the extra goodies. Super excited to shred the new gear in this years hunt for wave of the winter east coast. Amping so hard you guys helped finish a gear up for an all out assault on the entire mid and North East atlantic. You guys are so rad and your customer service is out of this world man. The suit is stellar, fits like a glove. Very mobile for a 6/5. Sealed seams and full furnace lining are sick. Digging the entry on this suit too. The neck seal and hood set up is righteous. Super excited to see how it handles this winter. You guys are so rad and it makes my whole week to receive a package from you guys. Happy 39th to you guys as well.

Billabong Furnace Carbon Ultra 6/5 Hooded Chest Zip Wetsuit SOLIDReview by wax rash wax rash
I was nervous wearing this out on a New England 28 degree dawn patrol. The suit is so stretchy I was skeptical I wouldn't freeze. I didn't, I was very comfortable. I was so warm and it was so flexible to boot, like my excel 4/3. It's a game changer for me.

I only gave it 4 stars because I haven't had it long enough to verify its construction. If it holds up well it will def be a 5 star suit.

Billabong Furnace Carbon Ultra 6/5 Hooded Chest Zip Wetsuit Single digits to sub-zero.... No problem!!!Review by Ron Ron
I just did my 3rd session with temps around single digits to sub zero. I am very impressed by this suit. I did not experience any flushes at all and it kept me warm for the duration of my time in the water. It's literally like they corrected all the problems I've had with other brands and made the perfect suit for my needs. The suit is nice and stretchy and is easily removed unlike some of the others I've had in the past where I felt like I was stuck in a straight jacket. I would definitely recommend it to anybody surfing in extreme weather where keeping your core temperature is vital.

Billabong Furnace Carbon Ultra 6/5 Hooded Chest Zip Wetsuit super-warm and stretchyReview by NJ NJ
I've had a few ~2hr sessions in 47-48 degree water (with 38-degree air), and I felt warm the whole time. Freely moves too. Looking forward to using in colder temps.

Billabong Furnace Carbon Ultra 6/5 Hooded Chest Zip Wetsuit Warmest nonrestrictive wetsuit I have ever worn.Review by Curtis Curtis
Asked Matt for his recommendation on the warmest 6/5 stretchiest wetsuit. After some research I made the purchase. Used today for the first time in a sizable swell. My local spot usually a few degrees colder, took a number of bombs on the head, literally felt no flush, extremely warm and flexible. It seemed lighter when wet in and out of the water.
I was in the wetsuit for 6 hours straight and wasn't cold in the slightest. I am rounding the corner to 70 years old and my extremities were warm the entire time. This is an exceptional wetsuit in every way. Going to purchase the same model in 5/4 as well.
