The Mutant from O'Neill has a unique detachable hood section which you can swap out for a regular neck piece, this gives you the advantage of a built in hood for the coldest sessions, then a regular neck with no hood when it gets a bit warmer.

The fluffy polypro firewall lining is on the inside of the chest and back panels with single lined slick skin neoprene on the outside to help avoid wind chill.

Seams are sealed on the outside with liquid seal and glued and blind stitched as you'd expect, this makes them durable and watertight but restricts movement a little bit compared to something like the Xcel Drylock or O'Neill Psychofreak.

Choose the Mutant if you want a versatile wetsuit for cold water surfing with quality features with the focus on warmth.

Choosing the right thickness for you

This is a 5/4/3 wetsuit, it has 5mm panels in the torso and legs and 4mm panels in the arms and 3mm panels under the arms, this ensures you get the warmth in the core of the body and the flexibility to paddle in the arms.

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.

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.

  • Performance wise, this is the best wetsuit I've ever owned its super stretchy, and flexible and virtually no flushes (never down my neck). I am annoyed with the build quality however, it is already showing signs of wear and I am dubious of how long it will last, additionally it is a nightmare to get off at first, and even now I've got it dialled in, it still takes about twice as long as a back zip design.

  • I hesitated to buy this wetsuit as I assumed my size was ML (medium long). I was pleasantly suprised the MS fits beautifully! Very light weight and flexible, a snug fit and the changeable hood/no-hood closure is magic.
