Best Diving Rash Guard Shirts for Boys of 2025

"My child is very picky about material and loves this rash guard. It fits true to size and is perfect for no gi or under the gi!"

"I've purchased several ELITE products for my Jiu-Jitsu kids, and I must say, they provide top-notch quality and are super stylish. My kids love everything!"

"This rash guard was a game changer for my daughter during competitions. It has a great length and doesn’t roll up while she’s rolling or competing!"

"I found the quality of this swim shirt to be excellent, but it does run small. My son, who is 9 years old and 4.5 feet tall, needed a size 12 instead of the size 10 I originally bought."

"I’ve purchased several O'Neill swim shirts for my son, and I’m so glad I did! The fit is just right, as they are loose enough to hide his midsection while still looking like a swim shirt. I was initially hesitant about the price, but these shirts are worth it."

"This rash guard fits my tall, slim almost 5-year-old perfectly in size 6. However, I was a bit disappointed that the color wasn’t as bright as the picture showed; it’s more of a green than a bright neon yellow. Still, it's a great rash guard overall."

"I ordered two of these watermelon-colored shirts previously. Now that my kids have outgrown size 8, I returned for two in size 10. We've used these shirts weekly during swim class in a chlorinated pool, followed by machine washes and dryer cycles. They’re holding up great, and I had to size up since the kids keep growing. I strongly recommend these shirts for skin protection and comfort while swimming!"

"After two years of use in Florida, my kids wore these rash guards year-round. I washed them on delicate and hung them to dry to extend their lifespan. While they did start to stretch and thin out after two years, they held up wonderfully before that. I've just ordered again, hoping for another two years!"

"I can't say enough good things about this shirt. It was a lifesaver from the sun during our vacation. My son got sunburnt on the first day, but this shirt saved the day for the rest of our trip. It held up well, dried quickly, and allowed him to enjoy being outside. I would definitely buy more!"

"This is probably my son's most often worn piece of clothing. It's perfect for the summertime as it's super breathable and easy to clean. Unlike most shirts, it doesn't attract lint or dog hair easily, plus it provides great UPF protection. It also fits adorably and can be worn with anything in his closet."

"I purchased this grey swim top and another two-tone blue one. The grey is an 8 and the blue is a 10, but surprisingly, the grey one is cut bigger than the blue. Both fit my son well and are made from a soft material. I wonder if the solid colors are cut differently than the two-tone options."

"The rashguard is of decent quality, and my son likes it. However, I didn't give it 5 stars because the extra small was supposed to be size 4-6, but we received an extra small 8. It's a bit big for my 4-year-old, but he likes how it fits, so we decided to keep it. Overall, they are decent rashguards and work well as athletic shirts too. I'd recommend them if you can find the right fit."

"I've hand washed this shirt many times in cold water, and I’m impressed that the fabric and logo have held up well. The material is nice, not too stiff."

"My 9-year-old son absolutely loves these shirts. I’ve bought four so far! They fit closely around the neck for sun protection while still being roomy enough in the arms and torso for comfort. Definitely worth the money."

"I ordered a size up for my son to grow into, but it actually ran small. It fits him now but is almost too small in the arms and shirt length. Make sure to order a size up!"

"I recently bought this Kids Elite Rash Guard for my daughter, and it's fantastic! The material is durable, lightweight, and breathable, making it perfect for her intense training sessions in MMA & No Gi BJJ. The fit was exactly as expected, and it's the most comfortable top she has. It doesn't ride up at all, and even after several washes, it maintains its shape and quality. I highly recommend this rash guard—it's definitely worth getting multiple for her to rotate through!"

"I purchased this rash guard for my son, who trains BJJ six days a week. The quality is amazing, and it feels comfortable without any itchiness. The stretch is just right, and the sizing is accurate. It arrived on time and looks exactly as pictured. I will definitely be ordering more Elite brand training wear!"

"My son is 4 ft 3 and 51 lbs, and this rash guard fits him perfectly. It was IBJJF compliant for the first-ever Pan Kids No Gi event. The great quality and sleek look make it a fantastic addition to our BJJ gear!"

"I bought a second TSLA rashguard for my son. Last year, he wore a size 6 but I got him a long sleeve xsmall (8). The sleeves were a bit long, yet the fit was perfect! He wore it for a week straight at the beach without any sunburns. This year, it still fits, but I needed a new short sleeve one. I got him a small (10) in cobalt blue. Again, the fit is great, and I believe he can wear it next year too! Great product!"

"The fit is just as I expected—good fit that doesn’t roll up at all. I’m unsure about the UPF protection, since I haven't used it during summers yet, but overall, it's a good swim shirt. I will definitely buy again."

"My 9-year-old loves it! It's not skin-tight and feels comfortable. It dries quickly and provides great sun protection!"

"This top was perfect for my boy. He's on the swim team and the water is pretty cold. I'm so glad I bought this; he is the only kid who doesn't shiver during practice. Quality is fantastic, and he swims every day for an hour. We got a size 8, which fits perfectly, with enough room to grow into. My only complaint is that the top had a funny smell that lasted a few days. I would definitely recommend this and will probably buy another for my other boy."

"I found this to be not just your regular neoprene top. It feels great and fits wonderfully. I can't wait to try it out in the water. O'Neill never disappoints!"

"We got this top to make swim lessons more comfortable in our not quite warm enough local indoor pool. It's perfect for the Caribbean as well, where my son wore it while snorkeling to stay a little warmer and to prevent sunscreen. I think it's a great choice!"

"My sensory defensive child loves wearing this as a tight compression shirt and rashguard. The quality is great, and what you'd expect from the brand. However, after two washes, it did shrink."

"I initially bought size 12 for my 8-year-old, but I had to give it to a 4-year-old because it barely fit."
