Slumbersac Sleeping Bag

Sleeping bags for all occasions

Slumbersac Sleeping Bags have become an essential part of the bedtime routine, the safe and comfortable way for all babies to sleep. Slumbersac simply replace duvets, blankets and top sheets. Baby cannot kick off, or slip down under the covers, remaining at a constant cosy temperature while getting plenty of freedom to kick and wriggle.

Slumbersac baby sleeping bags ensure that your baby stays warm and cosy throughout the night. Made from the best quality materials, our beautifully soft and safe sleeping bags will help to make sure that your baby gets the sleep they need to give them the best start in life.  Slumbersac sleeping bags completely replace traditional sheets, blankets and duvets. Research has found that the ‘old’ way of covering babies causes discomfort, as top covers are easily kicked off or tangled, resulting in your baby becoming either too hot or too cold.

Sleeping bag TOG:

The tog rating or weight of a sleep sack determines its thickness and therefore how warm it keeps your child. The higher the tog rating (weight) the warmer the sleeping bag. Please follow our recommendations on the table below to determine which tog is the best one for you. The decision depends mainly on the nursery temperature.

  • 0.5 Tog light above 24 degrees
