100% Organic Cotton is what we look for in the PJs that we stock & Hatley Clothing certainly deliver. If you are looking for sleepwear for your little one that's free from nasty chemicals & made of the softest cotton...then you might just have come to the right place. Hatley do make some of the finest PJs on the planet. Super soft pyjamas that are ethically sourced just made bedtime a whole lot easier…..although we can't promise sleep-ins until 10am.
