    5 Review Stars By Ana C.

    I got this suit for my son when he was 2 years and 4 months old. The suit was a zise 3T and it was loose on him but not in a way that prevented him of using it.
    He used it a lot and it was really good at the pool and also at the beach, it helped him in colder days and also in sunny days as protected him very well from the UV.
    I bought a Speedo this year and the size is too small I am exchanging it for an O'Neill again; but in a size 4T.
    My son is still using the 3T and now it fits him just right, he is 3.6 years old now; so you can expect to get a full year of use off this suit.
    I always washed by hand, 2-3 times only at the washer; I recommend wasing by hand and centrifugating at the washer for a faster dry  time.
    The only con I see is the ziper in the back, I would like it to have the ziper in the front to foster my son's independence to use the bathroom.
    I recommend this product, my son loves it and he looks good on it too.

    5 Review Stars By SueBartel

    My son is wearing a size 6. He is 49 inches tall and 52lbs. It fits him perfect, still loose in the stomach area but that does not matter. The suit  keeps him warm in swimming lessons and at the lake.  I would highly recommend.

  • 5/5/2011 Love the soft fabric

    5 Review Stars By Swimmom

    This is the second O'neill shorty that I have bought for my son.  He is happy to go swimming because he doesn't freeze when he has the suit on.  The new fabric is very soft and the colors are great.

  • 5/27/2012 No purple lips, a must for every toddler/young child

    5 Review Stars By Just add water

    This is the second O'Neil wetsuit that we have bought for our son who is almost 5. The first one has been serving us for almost 2 years, mostly for swimming indoors (in those big pools where they keep water pretty cool). Compared to other kids (dressed in regular swim suits), our son is never cold, never shivers.. We also use it when going to the beach (Virginia) when the ocean water is cool/cold. Our son is 41 pounds/42 inches and size 4 still fits him well.

  • 6/22/2011 Great Purchase - Would Buy It Again

    5 Review Stars By Subguy8

    First, I ordered this product at 3:50 pm eastern time; I paid for next day shipping; and I received the product the next day - couldn't have been happier.

    Second, I struggled with the size.  I would say to follow the size chart and it is accurate.  My son is in the 90% for height and weight, and I thought I might need a size 2, but he fell in at the top of the size 1 chart - glad I got the size 1 because it fit perfectly.

    We used it at the beach - some sand got up the legs but not much.  The other thing it did was protect him from the sun - we used sunscreen, but you can definitely see wear the wetsuit was.  We also used it for indoor swim lessons (cold pool) - the swim instructor said that it was the best thing he could wear since it made him a little more buoyant and it kept him warm.  

    This is a great product.  I will buy a pink one for my daughter when she gets old enough.

    Good slender size for "fit" toddlers and young kids. Length in torso offers room to grow.

  • 2/19/2012 Great Suit

    5 Review Stars By Robyn G.

    My three year old twins wear their wetsuits for swim lessons 3 times a week.  They love them and are much more active in the water now that they are a bit warmer.  

    They sizing is a little weird, but as long as you read the sizing chart you should be fine.  

    So far they have been a great quality and we have had no issues with anything.

    5 Review Stars By Karen

    I got this for my 3 year old son as he was always shivering and complaining about how cold he was during indoor swimming lessons.  I have been extremely impressed, he has not complained about being cold since wearing this wetsuit.  I really looked around before buying and this definitely seems like the best bang for your buck!

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.
