Kids are all about comfort and that is why they will absolutely love their Bermies. Our boys swim trunks are made out of 90% recycled polyester and 10% lycra which means these swimsuits are stretchy, breathable, fast-drying, and, most importantly, extremely comfortable. Our trunks also come with a built-in compression liner made from super soft and smooth material. The liner is not too tight, providing enough give for kids during their growth period. Ideal for beach and pool activities without chafing or discomfort. There are two side pockets and a back pocket with velcro tab and elastic key loop in our best selling kids swimsuits.
