Kaiya Baby is a small brand that makes baby sleepwear. It is best known for its sleep sacks, which have a GOTS-certified organic cotton outer and a filling of camel wool mixed with Sorona polyester. It used to trade as Kaiya Angel and took its current name in 2024. It suits parents who want natural fibres and want to match sleepwear to the temperature of the nursery.

You can set the website to UK pounds. Orders ship from overseas, so allow longer than you would for a UK retailer, and note that the brand says any import duties and taxes are paid by the buyer.

The range is organised by TOG rating, the measure of how warm a sleep sack is. It runs from 0.5 TOG for warm rooms up to 3.5 TOG for cold winter nights, and each weight lists the room-temperature range it is designed for. You can also shop by age, from newborn to around four years old, and by style. Walker sacks have separate legs for toddlers who are standing and walking, and there is also a 3-in-1 sleep suit sack. The ClimaCuddle range uses merino wool and bamboo rayon and is OEKO-TEX Standard 100 certified. Many designs come in seasonal prints as well as plain colours, and you can add embroidery for a personalised gift.
