baby sleep sacks

Our collection of baby sleep sacks & newborn swaddle sacks are thoughtfully crafted in our signature organic cotton and bamboo from viscose fabric to ensure your little one sleeps soundly at night and naptime.

The organic baby sleep sacks are available in a range of colors and prints, as well as a number of different TOGs to suit every season and climate. The TOG determines the thickness of the sleep sack, so the lower the rating, the cooler it is. For the warmer months, or whilst you’re on holiday, our 0.5 TOG summer sleep sacks will help your baby or toddler keep cool all night. As the temperature drops and the chillier seasons draw in, keep them snug in a 2.5 TOG winter sleep sack. The versatile 1.5 TOG can be used safely throughout the year by changing the layers worn underneath.

Our bestselling Clever Sleep sack is innovatively designed to ensure little ones have a safe sleep. It features a double-directional zip for quick changes and a clever opening for a stroller so they can sleep undisturbed on the move. As your child grows, the sleep sack's length can be adjusted to fit from 8-9lbs (4kgs) up to 2 years.

Our newborn baby swaddle sack has been designed to replicate the natural cuddle of the womb so new arrivals feel comforted and safe when they sleep. All our sleep and swaddle sacks are made from high-quality fabric to be worn, washed and passed on again & again.
