The Xero Furnace is unusual in that it has the same thickness of neoprene, 5mm, all the way through the wetsuit, most wetsuits have thicker neoprene on the body and legs and thinner panels on the arms for stretch, but the Furnace goes for a different plan, giving you thick fluffy lining throughout nearly all the body and leaving it off for the arms and under the arms, giving you the warmth of 5mm neoprene with a boost in flexibility because of the lack of lining.

We like the lining, it makes it comfortable and like all the other thick linings on different brands it traps more air to give you better insulation and trap more heat inside the wetsuit.

The seams are all stitch less, with thin beading on both sides of the arms and just the outside of the rest of the suit, with flexible, durable tape on the inside throughout the body and legs.

Stitch less seams are the new standard in top end wetsuits, giving you more flexibility and less chance of water getting in, we've tried a couple of the front running stitch less suits last winter and we're convinced that it's an advance that really works and is here to stay.

Another nice touch is the cinched, fused edges of the panels on the arms and neck, this is something we've seen in other wetsuits and it gives you a nice comfortable edge and makes it less likely you'll get a nick in the panel too.

If you've had problems with tight necks around the Adam's apple then the new range of Billabong wetsuits have the solution, they've got a contoured collar which dips at the centre to give you a bit more breathing room. There's a nice liquid dipped strip around the outside of the arms which should give a nice seal and makes it a bit easier to grab the cuffs when you're pulling the wetsuit right way out too. The attention to detail in this flag ship wetsuit is really noticeable.

We'd recommend going for the Xero Furnace if you want warmth, it's going to be as flexible as a full 5mm wetsuit can be and warmer than most other wetsuits in the same price range, if warmth is your priority and you don't want to go thicker than 5mm, this is a great option.

Choosing the right thickness for you

This is a 5mm wetsuit, it has 5mm panels throughout the wetsuit.

The best thickness of wetsuit for you depends mostly on where and what time of year you will be surfing, 5mm is the most popular thickness for year round surfing in the UK, with the right accessories you can use a 5mm wetsuit even in the coldest months throughout the UK.

We have created a guide which goes into more depth about choosing the best thickness for you so if you've got any doubts take a look at the msw wetsuit thickness guide

Choosing the right size for you

Getting the right size wetsuit is critical, the wrong size will not keep you warm and could end up putting more stress on the seams, different brands use slightly different size charts so you may not be the same size across different makes of wetsuit, we suggest looking at the size chart page to judge which size will be the best fit for you.

If you have any questions about the differences between wetsuits, the fit or the thickness that would be best for you give us a call on 01548 854660 or an e-mail on where we're happy to help.

  • Finally got out in this yesterday, water was 10 degrees, sun was out, light wind and this wetsuit was almost too warm! By the time I had paddled out I was pulling my hood off and sticking my head underwater to cool down, and kept my hood off for the rest of the session... Never worn a wetsuit like it, amazing. Should work really well in coldest, darkest February. The trade off of course is it is quite thick and heavy, this is my first all over 5mm so I can't say if it's better/worse than others in terms of flex, but if your not the strongest paddler (like myself) then be prepared to work a bit harder!
