Things you need to consider before buying a Sleep Sack

The main factors you need to consider are size, tog rating, sleepwear combinations, zip position, fabric type, and travel and other features.


When deciding on a size, base it on your baby’s current size. Most mommies want to utilize larger sized sleep packs to accommodate their baby’s future size. While it can look like you would have a greater value in buying something that he will grow into, there is also a higher risk of buying something that cannot be of much use now.

When your sleeping bag is too large, there is a greater tendency that your child may slip down inside the neck or slide around – you would lose the primary usage of the sleep sack.
