Shop Lands' End to find the perfect pair of swim trunks for the little boy in your life. Our collection of little boys' swim trunks come in sizes 4 through 7 and a wide range of styles, colors, and patterns. You're sure to find a piece that can keep any young boy feeling comfortable and confident. Each little boys' swimsuit at Lands' End comes with a faux fly, a full elastic waistband, and a functional drawstring, allowing them to get changed quickly and customize the fit. They'll get even more comfort out of their swimwear with the built-in mesh liner.
Though you can customize the size and design of the swim trunks when you purchase them, all of our little boys' swimsuits come with a few standard features to make them as functional as they are fun. Every pair of trunks comes to just above the knee, no matter the size or style you choose. Additionally, our swim shorts are made with a quick-drying material, allowing your active boy to go on his next adventure without having to slow down to dry off.
It's difficult to keep kids covered in sunscreen, especially when they're preoccupied with water fun. That's why each pair of our little boys' swim shorts have a UPF 50 sun protection rating, meaning they block 98% of the sun's harmful UV rays, effectively protecting the covered areas from UV rays. If you're looking for added protection from painful sun damage for your little one, consider pairing their swim shorts with one of our boys' rash guards.
If you're worried about more than just burnt shoulders, you can shop our selection of water gear to find even more useful pieces. For instance, you can keep their feet protected on hot cement or rocky riverbeds with a pair of our super comfy water shoes. Whatever your needs are, you're sure to find a pair of little boys' board shorts that are comfortable, fun, and, best of all, functional.
