Hi, I‘m Cloud Bucket Hat and I’m ready for a new head to be my best friend! I am made of a grey coloured nylon which means I’m lightweight and breathable. I will provide sun protection and style for anyone! You can adjust my circumference to make me tighter or you can detach my chin strap if you prefer that look. Material: Nylon Rated UPF50+ Excellent Protection 4 sizes to fit babies, kids and adults Sizing: Mini - for babies - 40cm - 44cm Midi - for toddlers - 45cm - 50cm Maxi - for school kids - 51cm - 56cm Mega – for big kids and adults - 57cm - 60cm Suggested ages are for a guide only. Please measure your child's head where possible as all head circumferences are different. We suggested sizing up if you are after a looser fit, but a firm fit will prevent it from easily falling off your child’s head. They are a smaller fit to our caps. * Please note that colours and sizing may vary slightly due to your monitor and production runs.
