Rated 5 out of 5 by from Geat Swimsuit! I bought this for my youngest granddaughter after having had such a great experience w/ the swim shirt set I had previously purchased for her older sister. The items protect their fair skin and are very durable. Their Mom was very excited to receive another Coolibar item, however we did exchange the item for a smaller size because she feels these suits/shirts run a little large.

Rated 5 out of 5 by from Perfect for newborn We spend most of our summer at the beach, pool, or on the lake and this outfit was perfect since the baby can't wear sunscreen yet. Highly recommend for babies born in the spring and summer. He is going on his third month of wearing it and it still fits him great!

Rated 1 out of 5 by from Poor craftsmanship My 6 months old wore it the first time today and the stitches came apart. Poor craftsmanship. Very disappointed.

Rated 4 out of 5 by from Comfortable fit Our 1 year old kept getting sunburned no matter what sunscreen I used. I purchase this one piece suit and its been great! My only worry is since hes crawling is that he will rip the knees out as they are starting to show wear after only the 3rd time wearing it. Otherwise very happy with the suit.

Rated 1 out of 5 by from Tearing up already I have used this suit maybe 10 times and the material is coming apart. I love the concept but expected it to last all summer.

Rated 5 out of 5 by from Love it So far used it at the beach in Florida in June. No issues- no sunburn , and not too heavy weight material. Only thing was felt legs were a little short.

Rated 5 out of 5 by from Love it! Why don't more baby swimsuits have hoods?? I love that it covers everything and I only need to worry about putting sunscreen on his feet and face. I avoid doing his hands because he only turned 5 months and puts them in his mouth constantly. He's 76th percentile in height, 74th in weight, and wears 9 month clothing, so I got him the 12-18 since people said it runs small. It fits over his chubby thighs and I like that as he grows and perhaps gets a little leaner it'll still fit him. He's very comfortable with it on and the hood stays on his big head and even has a little extra coverage for the sides of his face, which I love!

Rated 5 out of 5 by from Complete Coverage for Tots Last summer, I purchased a few full coverage suits from Coolibar - one hooded, one not. Our baby was only five months old so sunscreen was not really an option. These suits were absolutely amazing - plenty of room (didn't need to squeeze it over chubby thighs) and full coverage. They also allowed for easy diaper changes. I especially love the hooded suit (we had the pink one with whales - so adorable which has been replaced this year with flowers in the next size up). I never had to worry about my little one as she had as much fun as a five month old can have in the sun. My girl is very tall and skinny but I feel the suits run true to size. It's nice to have the extra room/length to cover hands and feet. I'm a repeat purchaser and as a new mom, I have recommended this brand to all my new mama friends.

Rated 5 out of 5 by from Soooo cute and great sun protection! I bought this for my grandson who is 10 1/2 months old. I bought the 6-12 month size and it just fits. Wished they had a bigger size available but will wear this until he outgrows it. Love it!

Rated 5 out of 5 by from Loved the attached hood! Baby won't keep hats on Great swimsuit! The attached hood was so useful since my baby won't keep a hat on. Totally worth it

Rated 5 out of 5 by from Comfortable, functional and cute! The one- piece style provides excellent coverage, and the lightweight fabric allows him to stay cool playing in and out of the water. The snap and zipper closures are high quality and make it easy to change his clothes and diaper. This has exceeded my expectations in every way, and I would definitely recommend it.

Rated 5 out of 5 by from Ready for new grand baby ! Arrived when expected, well packaged, and certainly adorable. This is for our first granddaughter expected the end of April. It appears to be well made and will cover baby from head to toe...we have a pool and spend countless hours in it during the summer months and this should protect her nicely! Can't be sure about the size yet but looks like it will certainly fit her this summer.

Rated 4 out of 5 by from Just what my baby needed! Love this swimsuit! Its adorable AND protects my baby's skin. She likes the feel of it and never complains when I make her wear the hood. Great product. Only complaint is the sizing. My daughter is almost 6 months and maybe in the 80th percentile for height. I purchased the 6-12 month size but I'm pretty sure she'll be to big for it in the next 2 months. Still happy overall.

Rated 5 out of 5 by from Perfect I bought this for my 3 month old's first beach trip and it was perfect. She wore it all day at the beach even on pretty hot days and seemed comfortable and cool. We also had her under an SPF umbrella or tent at all times, but this gave her protection on the walks to and from the beach. And, of course, she looked adorable in it. She is a 13lb 3month old and the 6 month size was just right if not as little bit snug.

Rated 5 out of 5 by from Worth it! Purchased this for my 3 month old since he can't use sunscreen. He has used it several times: at the pool, at the beach, and out for walks. No burns! I love the hood because his neck won't burn and I don't have to mess with a hat, and he fits in the Ergo really well and I can cover his hands with the extra fabric. He never got too hot, and the temp has been around 90. He is 20lbs and 26" long so I purchased the 6-12 month. I think these must run small, so I suggest going up a size.

Rated 5 out of 5 by from Darling No need to fight my little one to put on sunscreen (other than face and feet). The whale pattern is adorable!

Rated 5 out of 5 by from Instead of sunscreen Most sunscreen says not for under 6 months, this hooded suit solved the problem , the babe loved the pool

Rated 5 out of 5 by from Perfect! I purchased this for my 13 month old son. He hates having sunblock put on, and with his wanting to move constantly, it honestly just wasn't an effective way to keep him safe from the sun. We purchased the hooded one piece with the zipper neck and button legs. The zippered neck made getting it over his head easy when dry or wet. The buttoned legs were a little challenging with a moving baby, but were easy to snap and well-made. I ordered the 12-18 month size which fits perfect, only a little short in the length. We got lots of compliments at the beach and are planning to order another suit for back up.

Rated 5 out of 5 by from Great fit and sun protection I love that his has full body coverage. I wanted to keep my 3mo old protected from the sun. But I have an active toddler that needs to be in the sun and pool. This was the only suit I could find that small that covered her entire body and had a hood. I searched for weeks and finally was able to find this. Thank you.

Rated 5 out of 5 by from Easy snaps, comfortable fit, hood stayed up! I bought this for a camping trip with my 14 month old. She's small, and the 12+ month size fits comfortable with room to grow. She didn't seem too hot in this, it breaths really well. She kept the hood up the whole time swimming unlike any hat I've bought her. It was easy to put on and take off afterwards when she was wet. I felt comfortable letting her swim for an extended time knowing she most of her skin was protected from the sun.

Rated 5 out of 5 by from Love it! I'm so glad I bought 2 because I use them all the time on my almost 11 month old. I bought one with the attached hood and one without the hood. I also bought a floppy hat. I actually like to use the hood with the hat because the hood protects her neck while the hat shades her face. As stated earlier, my daughter is almost 11 months so I sized up and bought the 18 months.

Rated 5 out of 5 by from true to size Easy to get on and off my son even when the suit is wet. Hood is nice and big gives great coverage on his neck and face. Shipped quickly to Canada.

Rated 5 out of 5 by from Great value I bought this for my son who's 3 months hoping he'd grow into it. It's perfect as it fits him as a long sleeved and full legged suit without swapping him. I know we're going to lots of use from this now and the months to come.

Rated 5 out of 5 by from Great buy It wasn't easy to find a rash guard with long sleeves and a hood! Very practical and easy to put on.

Rated 5 out of 5 by from Great Fit Love that I don't have to try to apply sunscreen to a wet baby every 2 hours. The hood is great because her sun hat stays dry for use after swimming is through. Easy access for diaper changes if necessary. Our daughter is tall and lean at 10 months old and the 6-12 month size fits perfectly.

Rated 5 out of 5 by from Adorable and excellent quality This one piece swimsuit is adorable, functional, and of excellent quality. I was impressed. I bought it for a new baby gift and they loved it. The fact that it has a hood is helpful to give baby extra sun protection. Leg snap closures for easy on and off. Would definitely recommend.
