This City Threads swim liner is a lightweight, quick-drying mesh-and-knit layer designed to wear under board shorts, replacing a scratchy built-in liner with something soft against the skin. The UPF 50+ fabric blocks the sun and the flat seams keep it comfortable through a long day in and out of the water.
Pull it on under swim trunks for the pool, the beach, or a backyard sprinkler, where it dries fast between dips and keeps chafing down. The snug, supportive fit suits active boys who never sit still in their swimwear.
City Threads has sewn children’s apparel in San Diego, California for years, focused on soft, skin-friendly fabrics made entirely in the USA.
