First Impression

by Sam feat. Charles (3m)

"It looks great & feels really robust. It’s so well designed & such a clever idea. It’s so handy for us to take swimming to keep Charles warm & snug in the pool."


The Verdict

by Sam feat. Charles (3m)

"I like that it has an all over protection of SPF 50, perfect for holidays. The integrated nappy is fab, saves all the hassle of popping Charles in another layer."

The full story

It's a tricky life, being a baby in summer. You want to kick & you want to splash around, yet you also want to be cosy & warm. Meanwhile, we want to keep them safe in the sun and we *really* don't want those pooltime pooptimes to spoil play!

This clever Baby Suit Cosy is like a swim suit, wet suit & swim nappy rolled into one. The soft rash-vest style material has SPF 50+ sun protection, while the neoprene style PU coated material adds an extra layer of warmth to the mix. For peace of mind, the leg cuffs fit around those chubby little thighs & accidents stay firmly in place 'til changing time. Closer call it 'seal to skin' binding. We call it genius :)

The integrated swim nappy is designed to be used over the swim liner, available separately.

About Close

In 2004, two mums started plotting. One had a passion for baby wearing & the other a love for cloth bums. The result? The Close Caboo Carrier and Close Pop-in range of reusable nappies and swimwear. Shop Close
