The Warm in One™ features a soft fleece lining, making it the warmest wetsuit in our range. Unlike many wetsuits, it contains no neoprene, giving it a soft, flexible feel that's comfortable for babies and toddlers. Its full-length sleeves and legs provide extra warmth and coverage for babies and toddlers.

Yes. Warm in Ones™ are ideal for Water Babies lessons, particularly for little ones who feel the cold. They must be worn with an approved double-layer swim nappy system underneath to meet lesson requirements.

For Water Babies lessons, your child should wear either a Happy Nappy™ with an approved inner layer underneath, or a Happy Nappy DUO™, which has both layers built in.

A Warm in One™ should fit snugly against the body without restricting movement. A close fit helps the wetsuit retain warmth more effectively while allowing your child to move comfortably during lessons.

No. The Warm in One™ is designed to keep babies and toddlers warm, not dry. Unlike traditional wetsuits, it contains no neoprene and instead uses a soft fleece-lined fabric to provide warmth and comfort. A small amount of water can enter the suit during swimming, but the fleece lining helps retain warmth, keeping little ones cosy both in and out of the water, even when the suit is wet.

Many parents choose a Warm in One™ because it offers maximum warmth, full-body coverage and comfort for their little one. It can help children stay happier in cooler pools and allows families to focus on enjoying their swimming sessions together.
