Little Treasure Hunters will love the new Treasure Chest Happy Nappy. Find the diamonds and pearls amongst the fishes and seahorses in this beautiful design.

This unique fleece-lined wetsuit is designed to keep babies warmer for longer during swimming sessions, both in and out of the water.

Lined with super soft fleece, and with full-length sleeves and legs, the Warm In One works by trapping air between the layers of the wetsuit and helps babies to regulate their body temperature, whilst the soft fleece lining makes them feel snuggly and warm. Cuffs around the wrists and ankles help to maintain warmth and keep barrier creams in place.

Available for babies aged 0 to 2 years, the Warm in One range matches our award-winning Happy Nappy range. Wear together for a cosy, leak free swim.
