Matt Says:

The 4/3 Mutant wetsuit from O'Neill is a killer option if you're like a lot of surfers and not into wearing a hood all the time. The zip in hood or neck can be interchanged, essentially making this two suits in one. External fluid weld on all seams, and Ultraflex DS Neoprene with a smooth skin chest panel round out this full featured wetsuit. Definitely one worth considering!


The O'Neill Mutant 4/3 Wetsuit is the most versatile wetsuit in the O'Neill Wetsuit line. Now with an easier entry and new graphics,the Mutant has been updated with 100% Ultraflex DS Neoprene making it more flexible and warmer than last years Mutant. Two suits in one, now go get some.

O'Neill Mutant 4/3 Hooded Wetsuit Top Notch Suit & RetailerReview by Gerald Gerald
My first purchase through Cleanline, and this is a class act retailer! They threw in a extra shirt in my size, some board wax, some other goodies and a hand-written thank you note for choosing them...
The suit is spectacular, it's contortionist entry style (no back zipper) but not too difficult to manage, it looks and feels great once on, with excellent lower body & especially upper body range of motion (I use it to SUP in the ocean), and it literally seals perfectly & does not allow water in through the neck, sleeves or ankles unless you pull it open and want to self flush it to cool off. It kept me very warm and comfortable in water in the low 50s, and the hood or simple neck versatility option is great. Can't go wrong with this suit or with CleanLine...

O'Neill Mutant 4/3 Hooded Wetsuit Great PurchaseReview by Brendan Brendan
5 was my first time purchasing through Cleanline and i will definitely shop again. Great deal (One of the best, no tax, no shipping) and the little extras they included along with thank you note go along way. Highly recommend. Had a mutant and got a good 3 years out of it. The hood option works great and never had to deal with initial water getting in on your first duck dive. Stayed warm during long sessions on those colder days. I then went with a Rip Curl Flash Bomb, good suit but don't like back zip and the LT size in O'Neill fits me better. Just got my new Mutant and can't wait to get out. Will update on 2013/14 model.
