I got these swim trunks for my little girl even though they’re technically for boys, and honestly, they’re perfect! The shark print is super cute and bright, which makes it really easy to spot her in a crowd of swimmers — a total win for this mom. The colors haven’t faded after several washes and pool days, and the fabric still feels soft but sturdy.

She says they’re really comfy, and I like that the inside liner doesn’t bunch up or ride weird. They dry pretty quickly too, which makes getting changed after swimming a lot easier. The waistband is adjustable, so I know she’ll be able to wear them for a while as she grows.

They hit at just the right length — not too short, not too long — and give great coverage for active kids who are running, jumping, and splashing all day. Honestly, I’d buy these again in another design without hesitation. Cute, comfortable, durable, and practical — everything you want in kids’ swimwear. Definitely recommend

Shark swim trunks

These swim shorts will be perfect for summer. They are thicker than I was expecting, but that’s a good thing. The colors are also very vibrant. The sizing is true to size. They are the perfect length for my son as well, which is great. He can’t wait to swim, so he can wear them.

Great swim shorts.

These swim shorts are perfect for the little ones in your life. I like that they have a fabric liner most of the way down the leg to prevent any bunching up. They also wash very well and tie so they don’t fall off.

Swim shorts

My son loves it so much. He wore it to the state park and he swarm with it for 3hrs, and it was not lose or falling in the pool. He particularly loves the print on it, and the texture is so beautiful and smooth.

Durability

Very cute swim trunks. Love the interior contrast lining color compared to the outside pattern. Pockets on the sides and one in the back make it versatile for your little to wear around especially if they like to collect things like shells etc from the beach. Our daughter wears trunks with a rashy for daycare and summer camp and these are perfect. You can see as she is 4yo the trunks in size 4/5 come straight to the knee so plenty of time for her to keep past one season (she's a skinny one). Also the interior lining is lengthenes out to form interior trunks and aren't webbing which is nice for boys since it prevents bunching.

Cute comfy swim trunks for boys or girls

It is still cold here in Iowa, so my son was only able to use these swim trunks in the hot tub.  He is 8 and a rather small boy. He said they fit perfect and didn’t cause any discomfort.  He actually Commented about how quick they dried after getting out of the hot tub.  I also like how they have upf 50 protection built in!

Great value young boys swim trunks

My son loves these shorts. I will say the sizing runs a little big, but they have a really good drawstring, which seems durable and made specifically for water. The outer short material isn’t like crepe paper like other trunks I’ve gotten. The best part is the undershorts. They are like boxer briefs so they fit snug, but they’re not potentially pinching anything. Even those are good quality and clearly a material made for water. Like I said, they run a little big in that they will fall down with activity if we don’t tie the drawstring, but for length, they’re perfect. They go right above the knee. Also, they have pockets.

Very High Quality Details

The shorts are really comfortable material and the liner is really nice color. I liked that there's pockets in the front and a velcro pocket in the back. I wish there was one pocket with a zipper so that they could put their things in them and zip it up shut so it doesn't get lost during swimming. That would be a perfect place to put pool tags for example. Overall I love the design and the color the material is very comfortable and it seems very easy to wash.

Great boy swim suit.

I tried it on my grandson, but it’s a little too big right now.  The material is very soft and appears to be well made.  I would highly recommend people purchase this for their young boys.  I will be purchasing more if they are sold at Sam’s.

Well made with quality materials.

The pattern is a navy with teal and green palm trees, a cute pattern for the trunks. I like that it had a draw strings to adjust and a long built in short length liner. The fit was larger than normal. My son usually wears an 8 and these were huge on him even with the drawstring. If buying I would size down.

Boys Swim Trunks

Falsely advertised. I specifically bought these because they were advertised as having the compression short style liner. When they arrived, they had the horrible mesh brief style liner my boys hate because it chafes. Super disappointed. Won’t let me upload a photo. 100% wouldn’t have purchased and can’t return online but I live 2.5 hours from my nearest Sam’s. Do better please!

Falsely Advertised—Terrible Mesh Liner
