Rated 1 out of 5 by from Neck opening too small I found the neck opening to be too small for my 4 year old. This one is going back. Unfortunately she doesn’t like any of the other styles. Please make more w snaps or zippers around the neck to make it easier to get on and off!

Rated 3 out of 5 by from A bit disappointed... I have been a big supporter of the Coolibar brand and have purchased several items, from hats and scarves to bathing suits, dresses, and rash guards. I have been generally happy with most purchases. However the quality and durability of the kids rash guards is very disappointing. Last years Coolibar rash guards were paper thin (I could see right through them!) by the end of the summer so I purchased 2 new long sleeve rash guards for my boys this summer. Summer is not even over yet and I had to replace them with another brand because they became so ridiculous stretched out my kids couldn’t swim in them anymore- the arms stretched out and hung a good 5-6 inches beyond their hands and the shirt hung like a dress on them. It was like they had webbed hands because of the the sleeves. They also became extremely thin. I always though the fact that the sun protection does not wash out of your garments, that is lasted the life of the garment, justified the higher prices. However, if the garment doesn’t even last a season, that doesn’t matter.

Rated 5 out of 5 by from Swim shirt My daughter has a sun allergy. This allows for protection without sunscreen which further worsens her issues. Shirt has washed well and held up in our pool. Love these products but they are very expensive. Luckily I was able to score this one on clearance. But was still $25!

Rated 5 out of 5 by from Sun swim shirt I like the grip strip on the back. I love the feel. And the kids are fine wearing it. That's what matters

Rated 5 out of 5 by from Screen printed designs have lining layer in front It is not stated in the description, but the shirts with screen printed designs have a lining layer in the front, which makes the shirt heavier weight than the standard Coolibar swim shirt. Stick with the swim shirt options without the screen print if the appeal of the Coolibar brand for you is the lightweight SPF swimwear, which it is for me.

Rated 5 out of 5 by from Great fit, worked perfectly! We bought two of these for our daughter for a caribbean vacation. They fit perfectly and kept her burn-free everywhere they covered for hours in the pool and ocean. She was totally comfortable and had no complaints about wearing them.

Rated 5 out of 5 by from Great shirt I bought two of these at the beginning of the summer for my sons for the beach. They held up great! The beach we go to has very fine sand that gets stuck in all their swim shirts except this one stayed sand-free the whole summer. I have ordered 2 more for next summer.

Rated 5 out of 5 by from Sunscreen...bye bye This is my 4th or 6th youth swim shirt purchase in youth size (I have more in adult sizes). I am very pleased with my current and past orders. They hold up well, protect skin without the mess of lotions, easy to swim in the water with them on when wet. One thing I do recommend is having the right fit, when they get wet, they do stretch giving you extra material. With the children's size, it hasn't interfered with swimming, the more snug the more speed, a little bigger also helps taken them off when wet and might give you two summer seasons instead of one. What I do wish is that they all came with the option of a zipper at the neck for easier on and off, the younger size has them. It's not a deal breaker though. I recommend them to all ages.

Rated 4 out of 5 by from Good quality but pricey for a 4 year old I bought this for my grandson age 4 Great fit and quality for sun protection at the beach. Only suggestion would to put a draw string or something for the waist as the pants keep slipping down.

Rated 1 out of 5 by from Heart Emblem peeled off I have purchased hundreds of dollars of Coolibar items and fortunately this is the only item I have a complaint about. On the first wearing the heart peeled off and she was only swimming one the ocean and then in the pool.. never saw the washing machine. If you have a Large I would be happy to exchange it

Rated 2 out of 5 by from Good protection, poorly made Nice colors and good protection from the UV. However, after only 1 week at the ocean this shirt started to come apart at the seams. Such a pity!

Rated 5 out of 5 by from Great summer camp shirt I bought this for my 3 yr old to wear during outdoor water play at camp. It is lightweight and protects him from the sun.

Rated 4 out of 5 by from Very Cute and Functional My granddaughter loved this and wore it constantly on a Disney Cruise. Nice to not have to be putting sunscreen on constantly. Would like to see a longer length in the back to give a little more cover. She normally takes a 9/10 but Coolibar runs big and the 7/8 fits well. My last purchase lasted her 2 years until she grew out of it. Easy to care for.

Rated 4 out of 5 by from love the color Love this shirt for the color and stay put band along the waist. It seems to run slightly small (short)

Rated 3 out of 5 by from Quality has gone down and fit has changed I agree with another reviewer that the way the shirts used to "swoop" down in the back to protect their lower backs is what separated Coolibar from the rest. With just a straight back, it's degrades the quality of the product. Also, My daughters have been wearing Coolibar since they were babies. They're now outgrowing their XS and S sizes respectively, but when I ordered the next size, they are enormous. They are floating in them.

Rated 2 out of 5 by from Previous Design Better This design has a straight hem, the previous design had a "swoop" so when the child bent over the lower back and upper bum was covered. Now these are just slightly better quality swim shirts that what I can get at Target. Not really worth the price now.

Rated 5 out of 5 by from Great Swimming Shirt I got the plain blue shirt to my 7 year old son. The color is beautiful and the shirt looks great on him. He loved it. I liked it as well and specially the fact that is has a line of anti-slipping at the bottom, keeping the shirt in place while swimming. I will definitively buy again and I hope more plain colors will be available.

Rated 5 out of 5 by from Convenient I bought this in M for my daughter. The texture is so comfy that she wears it everywhere. Its convenient because it doesnt look like a swim shirt so she need not change when we arrive at the waterfall. Just dip right in. At first we werent sure of the color but its very pretty in real life. Suits our brown skin well.

Rated 5 out of 5 by from Very good quality I bought this shirt for my daughter, and she has worn it nearly every day since we purchased it about a month ago. The fabric is smooth and soft, it's very comfortable, and it doesn't make her overheat. Definitely will buy another next summer (I think this one will last, but it's starting to get stained from the constant wearing). I probably should have bought two this summer so I could wash one and it would have time to dry before the next morning!

Rated 5 out of 5 by from Perfect for sun protection on hot days My son is obsessive about fishing and I can not keep him off the dock. This shirt provides excellent protection from the sun with out overheating. He does not protest about lack of comfort preferring his sun block shirt over sunscreen lotion! I sized up to allow growing. Where we are on the bay we have a bit of a black mud that has stained other materials, these shirts wash well and the material stays vibrant. In addition to wash ability the fabrics look rich! This is a decent quality product! We now have purchased a second!

Rated 3 out of 5 by from Nice Looking Shirt But... Very nice looking shirt however, the down side was that it ran big. I went ahead and purchased another one but one size smaller. I figured I'll save the first one for next year. Then, when the smaller one arrived, the opening for the head was a little tight to fit my daughter's head. She still managed to put it on. Despite these things my 7 year old daughter loved her shirt.

Rated 5 out of 5 by from Great shirt! Beautiful blue color. This is the 3rd or 4th I've bought for the kids. They hold up great after multiple washes and last over several summers as hand me downs. Provides great sun protection!
