The O'Neill HyperFreak Fire 5/4+mm wetsuit is the latest and greatest addition to the O'Neill winter wetsuit range.

The HyperFreak Fire version of the all time great Hyperfreak range is all about more warmth, better durability and comfort and the best performance any wetsuit can deliver. It's loaded with new features but the big advance is the new TB4 rubber. This is the best neoprene any of us here have ever worn, simple as that.

The HyperFreak Fire is constructed with the super light TechnoButter TB4 and TB4x neoprene, the stretch and memory with this neoprene is insane! Minimal seam construction = more flex, improved durability and more warmth.

Other key features include the 'unfinished' low-profile cuffs, durable Krypto Knee Padz, patented Front Upper Zip Entry, Pre-Stretched TB4X lightweight neoprene that sheds water rapidly and increases warmth, BlindStitched and Triple Glued watertight, internally taped seams for better durability. There's also an extra 0.5mm in the thickness of the suit to add a little extra warmth, no loss of flexibility of course.

With the addition of some good quality wetsuit accessories this classy looking 5/4+mm should see you right through a UK winter unless you surf the colder temperatures of Scotland and the North East where a 6mm hooded suit might be more appropriate.

Getting the right winter wetsuit with the perfect fit is one of the most important purchases you'll make if you really want to enjoy and progress at your chosen watersport. Between the staff at Boardshop we have well over 100 years of combined wetsuit knowledge, and are well placed to advise on that all-important wetsuit choice.

Hyperfreak fire 5/4
Had the chance to test the new hyperfreak fire 5/4 and what can I say excellent. Really comfortable and so warm really impressed. The TB4 drys so quick within 20 mins. That’s not the rest of it mind. Draws the water away from the body really well. Amazing suit.

Just received my wetsuit yesterday, took just over 2 weeks to arrive in the Canary Islands, which is about par for the course here (I really appreciate the free shipping BOARDSHOP!). Went for a first surf today and the suit felt great, absolutely no flushing, toasty warm for over 3 hours with quite a strong wind, air and water both approximately 21C. I know that probably sounds like a pretty warm day if you live in the UK, but I've been absolutely freezing lately, cutting my last few sessions short in my older wetsuits, and it's the cold wind that does it.

The fit and finish of the suit really seems quite good, all the seams are carefully taped with neoprene on the inside, and I can't see any weak points like I have in my current wetsuit (Quiksilver Syncro), which has developed holes in a number of poorly designed joins. The O'Neill suit isn't nearly as stretchy as the Quiksilver, but I can't say that I actually notice the difference in the water, I suspect that the importance of how flexible a neoprene is is over-rated in a 3/2, at my level of surfing anyway.

The suit's very comfortable. I really like the design of the overlapping flaps underneath the chest/head opening on the suit, they form a kind of close-fitting secondary collar that prevents any water from flushing into your suit. The zipper is also a standout for me: it's placed a touch higher up than on other suits I've worn, closer to your neck, which keeps it nicely out of the way, instead of running right across your chest. The actual zipping mechanism itself is also a good deal smaller, lighter, and less chunky than on any other wetsuit I've worn, making it less noticeable when paddling.

In terms of fit, if I were to order another, I think I'd go with an MS instead of an M. I've lost a few pounds recently and there's a bit of extra material in the biceps and armpit region, it's very subtle and not noticeable in the water, but still. In case it helps, I'm 5ft9/175cm 158.5 pounds/71.9kilos, 35 athletic build with fairly broad shoulders and back.

For the money, the suit's very good value.
