Boys Swim Trunks Boxer Brief Liner (sizes 6-14) | “Surf's Up"

I wanted to find swim trunks for my son that had a soft liner, like Chubbies, but without the hefty price tag. These fit the bill! The boxer style liner is so soft and comfortable, and doesn’t chafe like the old school mesh liner. My son loved having so many fun designs to pick from too. Highly recommend!!

We bought these swimsuits for all the grandkids in our family- 31! We were impressed with all the styles- great quality and style. Customer service was also great to work with. We will definitely order again!

I purchased soze 8-10 for my son, who is 7.5 now, and it fits him comfortably now - with space to grown into.
The colors are even more amazing in person, and my son really likes the design.
I would definitely purchase more items from here.

I love the print of this suit. It’s comfortable for my 8 year old wearing size 8-10. The only thing better than this suit is Swim Zip’s customer service! We have been buying from this company since my twins were babies and I haven’t found anything better. Cute, comfortable, and protective, checks all my boxes!

This print is adorable and the fit is perfect. I love that they’re just the right length-trendy and fun!

Perfect color to keep track of child in the pool. Fracture to size

These hi-vis green swim trunks are amazing! The liner is super soft, and the pockets are actually deep enough to hold things. My son loves the silky-soft gray liner, and I love that they aren’t see-through at all. The bright color makes it so easy to spot him anywhere, whether we’re at a busy pool or the beach. I 100% recommend these swim trunks to any boy mom — your son will love them, and he’ll love you forever for buying them!

I WISH I FOUND THESE SOONER! My son won’t wear any other brand. These are the perfect fit, and I love the tie waist. The silky liner is so comfortable for him that he wears them all summer long — seriously, I have to buy 3 pairs! He wears them all day and doesn’t change until bedtime, even after swimming at the pool. I won’t buy swim trunks for my sons anywhere else, and I’ll definitely be purchasing them every year.

My son won’t wear any other brand! These are the best boys’ swim trunks — the perfect fit, and I love the tie waist. The silky liner is so comfortable for him that he wears them all day long and doesn’t change until bedtime, even after swimming at the pool. I also love the hi-vis colors because busy pools and beaches can get crowded, and these make it easy to spot my son in seconds. I’ll definitely be purchasing them every year!

My son won't wear any other brand. The silky linear is so comfortable for him, and he wears them ALL DAY LONG. He doesn't change until bedtime after swimming at the pool. I will purchase every year. Just wish you had 14-16 because mens Smalls are too big for him.

My 8 year old grandson is a big kid. The size 12-14 fit perfectly. We love the color as he is easily visible in the pool

100% best men’s swim trunks! I wish I found them earlier! My husband wears them each time we go to the beach or pool!

Love the color! Good quality

These are hands-down the best kids’ board shorts! The boxier brief liner is a game-changer—no chafing, no complaints. My son wore them for 10 hours straight, running in and out of water and playing in the sand, and he was completely comfortable the whole time. They’re durable, lightweight, quick dry and perfect for active kids. Highly recommend!

I ordered the father and son matching trunks as a Christmas present for an upcoming family trip to Jamaica and was pleasantly surprised at the quality of both suits. Construction is solid, high quality and the fabric is luxurious, if swim trunks can be luxurious! The print is colorful and fun. I'm confident both will hold up beautifully to the sea water and cholorinated pool. This was an outstanding purchase!

After years of buying my kids swim trunks from Amazon and big brands, these ones are MUCH better quality and my kids are actually happy to wear them rather than give me grief about the netting that they hate.

I've bought my boys so many different swim trunk over the years. These are such great quality and don't have the nets (my kids hate the nets) but rather have proper short inside.

Ordered for my son to wear for a cruise and for the pool this summer. The grommets had come off upon arrival but I did not have time to exchange before we left on vacation. They still worked fine and my son said they are very comfortable. Will never buy swim shorts with the mesh underwear again. Love the colors and designs!

I bought the entire family matching swim wear and was thrilled at the variety of prints available for all the members of the family! I have looked elsewhere for family matching swim wear and other companies either didnt have prints available for all family members or size ranges were not what we needed. I stumbled across SwimZip on a Facebook ad and checked them out. I AM SO GLAD I DID! All of our suits fit exactly as expected, the prints are vibrant, size ranges were also available in plus sizes, shipping was fast and exchanges were easy. The fact that these suits are SPF based is an added bonus! We will be customers for life!

These are nicely made shorts, love the liner (not mesh). However, will have to wait another season to use as they run big on both of my boys.

Comfortable. Now he can match me.

Purchased the 6-8 size for my 6 year old (4+ feet, 50lbs) and he loved them. They will fit them for a little longer as we tightened string to fit waist. He found these very comfortable and liked that they had the inserts as shorts rather than the brief style. Look forward to more patterns to purchase.

I was happily surprised that they were perfect length ,not too short and not too long and super soft inside. My picky 9 year old approved!

My son will pick this suit over all the others for the lining that are soft and like his briefs! Mom loves the bright color and easy to spot.

These are really cute shorts and, like all SwimZip products, well made and comfortable.
