What to know before buying

The maker says the briefs can be worn without anything underneath, but suggests a liner for easier cleaning and allows a disposable swim nappy underneath if desired. Follow any swim-school double-nappy rule. Hand wash in cool clean water, dry away from direct heat or sunlight, and do not machine wash or tumble dry.

Who is it for?

A good fit for

Parents seeking a sporty reusable swim-nappy alternative for toddlers or older babies.
Families whose swim school accepts this style, either worn alone or as part of its required double-nappy system.

Less suited to

Buyers who need ordinary machine-washable swimwear or want to avoid hand washing.
Families who need a swim nappy for urine containment, since the listing describes protection against faecal leaks rather than urine.
