    rating star By Margaret L.

    We use this product so that our 7 yr. old son can swim in the water without turning blue.  This wetsuit worked miracles for him.  He no longer felt the coldness of the water and moves in his suit freely in the water.  He now enjoys swimming at the school swim program.  He looks forward to his class every week with no complaints.  He also loves how he looks and feels in it.  What a Godsend!!!!

    rating star By Miche

    I bought this wetsuit for my 9 year old daughter to use for her swimming classes. It keeps her warm in the water for the full length of her class. She's a slim 9 year old, so size 6 fitted her perfectly. The material is very stretchy which enables her to do her strokes freely. Couldn't be more happy with the product.

    rating star By Very happy mom

    I bought this for my 16 month old and now she doesn't mind getting in and out of the pool.  This suit is amazing!!  Before buying this suit, my little one would be shaking uncontrollably and wanting to get out of the pool.  Now she wants to stay in.  When her swim lesson was over, I took the wetsuit off and her skin was actually warm.  I am in love!

  • 7/9/2012 Fantastic Kids Wetsuit

    rating star By Eric

    Our kids use these suits for swimming in our pool -temps around 72 to 76 F in late spring. Instead of only popping in for 10 minutes and coming out chattering. They spend an hour in the pool and we have to tell them to come out. One day they swam in the pool at 64!
    The wetsuits are good quality and lasting daily use without a problem after 2 months.

  • 6/16/2012 Oneil Toddler Swimsuit

    rating star By Mama

    Use for indoor swimming lessons in unheated pool by my 3 year old. He would shiver so frantically and go blue, at one point I thought he would die from the cold.  I purchased a half suit first, but that one only helped somewhat he still shook too much for me to bear and he obviously couldn't enjoy or get much from the lessons being so cold.  Now he wears the Full Wetsuit, he has no shivering and has progressed dramatically in his swimming and enjoys it.  He loves the suit and so do I.  Very good buy and worth the comfort of not seeing him shiver in cold pain.

  • 5/30/2012 This suit is such a life saver

    rating star By Leandra M.

    I puurchased this suit for my 6yr old. When we go swimming he spends 95% of the time out of the water because he's always cold to the point where his lips turn blue. The first day he wore it he stayed in the water for 2hrs straight before getting out for a bathroom break. The only down side is that I noticed after his 5th time wearing it one of his pant leg rolls up that's ok its such a keeper.

  • 5/14/2012 Perfect, easy, no blue lips!

    rating star By Bearsmom

    I purchased this wet suit for my 18 month old sons first swim class along with the iplay swim diaiper which fits perfect underneath and a pair of water socks.
    The 2T fit is perfect for him at 31 inches, 23 pounds. There is about 2 inches to spare in the crotch and room for growth but the legs arent to long at all. It fits perfectly snug and it is SO EASY to get on an off even when wet.
    The pool is kept very cold, to cold for children his age per the instructor. The other kids are all in just trunks or rash guards. They get in the water and their lips turn blue, they cry and they shiver uncontrollably. My guy is without tears or blue lips and can focus on having fun thanks to this wet suit!!!!

Jack O'Neill began surfing in 1952, before functional surf apparel was invented. While working for the Army Air Corps, O'Neill discovered neoprene foam in a DC-3 airplane. He then combined the neoprene carpeting with duct tape to create the first neoprene wetsuit.

Demand for O'Neill's neoprene wetsuits grew rapidly and he began a business selling the O'Neill wetsuits out of his garage. By 1980, he was a leader in the beach apparel industry with a thriving business. Since then, O'Neill™ has become a widely recognized and respected brand in the surf industry, continually creating new and innovative products. In addition to O'Neill wetsuits, they carry O'Neill boardshorts, O'Neill dresses, O'Neill hats, O'Neill rash guards, O'Neill swimsuits, O'Neill water shoes, O'Neill sandals, O'Neill life jackets and O'Neill t-shirts.

In addition to his business success, O'Neill also created a non-profit foundation for kids. O'Neill developed the O'Neill Sea Odyssey Program: a free, educational cruise that introduces kids to the microbiology of the Monterey Bay Marine Sanctuary, beginning at Jack O'Neill's doorstep.
