Key Features

• Sun protection: UPF 50+ fabric blocks the majority of UV rays, providing added defense for outdoor swim time.
• Safety-tested materials: Meets STANDARD 100 by OEKO-TEX so fabrics have been tested for harmful substances above regulatory requirements.

Who It's For

The trunks are ideal for parents of infants and toddlers who attend swim lessons or enjoy frequent pool and beach visits and who want a reusable, economical option that reduces waste.
