Best Rash Guard Shirts for Baby Boys of 2025

"I got this for my baby boy for the beach this summer. So far he has not gotten burnt! It washed well, and he looked really cute in it! Fits true to size. Did not take long to air dry and worked fine in the dryer too. Good quality, has not pilled or torn!"

"I purchased this for my 3-month-old, and I bought a size up. It’s big enough for him to grow into, and it has worked great in both the ocean and the pool."

"I bought this for my son who has very fair skin. We always keep him covered at the beach. My husband was initially skeptical about the white material protecting his skin when wet, but it performed excellently! It did not become see-through when wet, and it looks adorable!"

"I bought this for my 1-year-old, and he absolutely loves it! Now that he’s 2, it still fits comfortably. Great sun protection and very functional. Highly recommend!"

"These swimsuits are soft and true to size for my 9-month-old. They’re super easy to dress him in and perfect for the beach. Great material, no crying during dressing!"

"I purchased these for my 11-month-old with fair skin. They are perfect for avoiding sunscreen, and the zipper design makes them easy to take on and off, even when wet. I highly recommend these swimsuits!"

"I bought one in 3T to last at least a year, since we are in Mexico and it's not so practical to buy and pay for shipping here. The fabric is fine, dries quickly, and fits nicely. The sleeves are a bit long for my 2-year-old, but I think it's okay since she will grow into it."

"I purchased this for my 21-month-old who is average in height and weight in size 3T and it was perfect! A bit big, but I didn’t have to fight him to get it on, which is a win for me. The rash guard is super cute and dries fast!"

"I love this rash guard shirt! It fits true to size and is easy to get on and off my son. I didn't need to reapply sunblock where this shirt covered, providing great sun protection while he swam daily."

“I purchased a couple of Rugged Butts swimsuits last year from a friend and have stuck with the brand for my son ever since. The quality is great, with cute colors and designs that fit nicely. While we could find cheaper options elsewhere, we plan to keep buying this brand as our son grows because it’s worth the extra cost!”

“This rash guard is made of a nice thicker fabric that doesn't snag, and it's very comfortable. It's not too tight or loose, making it a reliable choice. I’ve bought this multiple times; every time my son outgrows it, I get a larger size for the next season. Other brands don't match this quality, and while they’re a bit pricier, I believe they’re worth it.”

“I bought this for my 10-month-old to wear whenever we’re out in the sun. I opted for size 2T, which works perfectly as it should last for multiple summers. The zipper allows it to fit now and over her head later. The sleeves are long, but I just fold them up. It provides excellent sun protection since she hasn't gotten sunburned while wearing it, and it matches RUGGEDBUTTS ocean camo swim trunks perfectly!”

"I bought the 18-month size for my 23 lb toddler, who usually wears 12-18 month clothing. It's cute and has a half zipper for easy on and off!"

"I was really impressed with the quality of the fabric. Although it's a bit shorter than I would prefer, the zipper makes dressing easy. Overall, I would definitely buy it again!"

"I absolutely love this swim shirt! The full front zipper makes it a breeze to take off when wet, and the material quality is superb. No more wrestling with my 5-year-old to get his wet shirt off. The UV protection is a big plus, and the fit is just right—comfortable but not baggy. Plus, it’s a clean, bright white that matches all our swim shorts. Great value for the money!"

"This shirt is fantastic for swimming and playing! The fabric is soft and stretchy, and I really appreciate that the zipper is covered inside, so it never bothers my son’s skin. The bright color is beautiful, and its length is perfect for two summers, even with my rapidly growing child. The full zip feature makes it so easy to remove after swimming. I’m very pleased with this purchase!"
