O'Neill Youth Mutant 5/4/3 Chest Zip Wetsuit with Hood serious suit if you are seriousReview by North michigan North michigan
I have purchased 3 of these suits over the past few years. My two boys (ages 9 and 12) are competitive water-skiers who train in tough conditions in the spring and fall. These suits keep them on the water in November and again in April when the ice is off the lake. The fit is great, the suits are extremely durable. Without these suits, training in 40 degree water would be impossible. My older boy likes the hood and the younger child prefers the collar only.

O'Neill Youth Mutant 5/4/3 Chest Zip Wetsuit with Hood My 5/4/3 MutantReview by Barnacle Ben Barnacle Ben
Hey guys You guys are still doing an awesome job!!! Thanks so much Josh for the hats and surf mags!!!!So I figured I’d write a review. My suit actually had a small rip upon putting it on, but that’s not your fault in any way, nor is it the fault of O’Neill. My fault completely. I ordered a size just a little too small. Usually I can fit a youth 16 because I’m a very small 29 year old man ???? Your customer service is awesome. It was a small tare that didn’t let water in so I made the repair myself. I just blind stitched the seem back and taped it myself. Again you guys are the best surf shop I think I’ve ever run across. I wish they still made a mutant 5/4/3 in a men’s small but there isn’t anything you can do about that. You still have my continued support. I’m gearing up for a hunt for next years wave of the winter east coast north and east coast south so I’ll be ordering all the necessary neoprene and gear that I need for that hunt from you guys throughout the summer. You guys are awesome and I really appreciated the goodie box you sent when I wrote the last review. You really didn’t have to do that at all. You guys absolutely deserve solid reviews. You take care of your customers and your business ethics are something a lot of surf shops could learn from. Thank you so much for the support.
