Best Rash Guard Shirts for Boys of 2025

“I bought this shirt for my son, who is 4'9" and 77 lbs. The large fits well with some room to grow. I could have opted for a medium, but I anticipate he’ll outgrow it quickly. The UV protection is fantastic; he spent the day in the sun without sunscreen and didn't get sunburned at all!”

“I needed a swim shirt to match my son's swim suit, and this one was a great price for our last-minute trip. He wore it all day and got zero sunburn, even where the shirt covered him. Though it was a bit large, he didn't mind at all.”

“This is my second time purchasing this shirt for my son. It's a great shirt for the pool, and the material holds up without fading from the sun. I have no complaints about its quality!”

"I ordered these for my 10-year-old, and he absolutely loves them! The colors and patterns are fantastic. He’s tall and thin, so they fit more like a smedium shirt, but once in the pool, they were snug enough to stay close to his body. The sun protection works well; he’s got a nice t-shirt tan!"

"I purchased this for my grandson, and he really enjoyed the colors and fit. They matched perfectly with his swim trunks. Great quality for the price!"

"I got these for my son for summer. I was a bit concerned they would be too short since he’s tall for his age, but they turned out to be longer than others. He liked the feel of the fabric and how comfortable they were on him."

"I love this shirt! Great quality and perfect color. It was a fantastic price, especially since it was on sale. It fits like a t-shirt, not clingy, and is super comfortable with its lightweight material, which dries quickly."

"I've had this Hurley swim shirt for my kids all summer, and despite being worn daily and left outside, it has not faded at all. We haven't experienced any sunburns, which saves us money on sunscreen. It's not overly stretchy, but it dries quickly and performs great for kids in the sun."

"I bought this rash guard for my son, who has sensitive skin. We've been using it at the pool and water park, and it has held up beautifully. Much lighter than other brands we've tried, it’s easier for him to put on and take off. The vibrant neon color is perfect for visibility. I was pleasantly surprised by the price, too!"

"I've purchased this shirt in multiple colors and sizes over the years. They last well and offer great skin protection from the sun. It's super lightweight and dries quickly, plus the appearance is excellent. The price is very reasonable, fitting like a dri-fit shirt rather than a thick rashguard."

"My 9-year-old loves how it fits! It's protective and comfortable, super lightweight, and dries quickly!"

"The color is bright, making it easy to keep an eye on my kids. The roomy fit and long sleeves are perfect for days at the pool, beach, or splash pads. I don't have to worry about reapplying sunscreen on their arms, which makes it easier for me to ensure consistent skin protection. It's a win-win!"

"I bought these shirts for my 9-year-old, and he absolutely loves the colors and how they feel. They are just right when he's playing soccer or sailing."

"My 6-year-old usually fits a youth extra small, but this shirt seemed huge compared to that. However, it still works well for him."

"My grandson is quite big for his age at just 6 years old, and we ordered a size that fits him perfectly. The full coverage and softness are great, especially since he enjoys being outside in the sun."

"I've been incredibly pleased with the Willit Boy's UPF 50+ Sun Protection Shirt. This rash guard has been a lifesaver during our family's lake trips. The bright yellow color is easy to spot in the water, providing added safety. The UPF 50+ rating offers excellent protection against harmful UV rays, ensuring my son's skin stays safe. The shirt fits perfectly and is incredibly comfortable to wear. It's lightweight and breathable, making it ideal for long days in the sun. The quick-dry material is a huge plus as it keeps him cool and dry. I highly recommend this rash guard to any parent looking for a reliable and comfortable sun protection option for their child."

"I bought this for my son to wear on vacation and it was perfect for days in the sun and afternoons in the shade. The head/neck opening is small, but this creates good sun protection around the neck, so I just helped my son get it on over the back of his head each time."

"Wanted a long sleeve swim shirt for my 8-year-old son, who is on the smaller slender side. The M fit him well, not overly tight and only slightly long in the arms. He wore it all summer for slip n slide and swim activities. Washes well and the color is super vibrant. So glad I purchased a medium as opposed to a small. The medium will fit him perfectly for next summer."

"I ordered this for my son, who is pale-skinned and sensitive to UV rays due to medication. After reading reviews, I got a size 10 instead of his usual medium. It fit perfectly! The shirt is slightly long, but it works for us since we needed to tuck it in. We've spent hours in the sun and he had no burns or redness! Plus, the neon green color makes him easy to spot among other kids. My only small complaint is that the neck hole is a bit snug when trying to get it on or off, especially when wet!"

"I really love the color and quality of this rash guard! It's perfect for when we're rafting and I need to keep an eye on my son. He moves around great with it on, whether it's wet or dry, and it dries quickly. Although it was a little snug getting over his head, it stretches nicely once it's on."

"My son expressed his excitement right out of the package, saying, 'Wow! I LIKE that!' Following the reviews, I decided to size up to a 10 since he just turned 9. It fits snugly, which might make it a bit tricky to take off when wet, but I love the Neon Orange color. It contrasts well with the water, making it easy for me to see him."

"I bought this swim shirt for my 13-year-old son to wear on a float trip with friends. I wanted something that would ease my worries about him frequently applying sunblock. I was thrilled with the quality when it arrived; it feels much more expensive than the price I paid. Plus, it has 50+ SPF, which means less sunblock hassle for me. I chose the white color to keep him cooler in our Oklahoma heat, but I’m tempted to buy more colors when I find another deal!"

"I ordered a second swim shirt from a different brand, and it just didn’t compare. I ended up returning it because this shirt is such a better quality. I’m really happy with this purchase!"

"I bought this for my son’s water day at school, and I was impressed with how quickly it dried. He loved it!"

"My grandsons wore their shirts all day at the pool. I highly recommend them for their quality and reasonable price."

"I found these shirts to be a great value for keeping my grandson sun safe while swimming. They are so lightweight that he wears it outside too!"

“I’ve purchased several swim shirts for my son over the last few summers, and they have been fantastic. The fit is true to size and the quality is impressive. He enjoys wearing them and finds them comfortable. They dry quickly and provide sun protection for his skin. However, I did have trouble removing stains from the white shirt.”

“I bought two of these shirts in different colors, and they feel like I spent much more. They are incredibly soft and easy for my 7-year-old grandson to put on and take off. They provide great protection from the sun and keep him warm against the wind. I’m considering getting some for my granddaughters too!”

“The color, size, and fit of this shirt are perfect for my son. The fabric is soft and not see-through, which is a bonus. Overall, it’s a great quality product and worth every penny!”
