Choosing a Tog

A tog measurement is a European warmth rating: the higher the tog, the warmer the product. grobag® baby sleeping bags are available in three tog ratings.

Check your baby regularly to ensure they do not overheat.

Your grobag® baby sleeping bag comes with a free nursery thermometer to help you select which tog baby sleeping bag to use and what sleepwear to put your baby in.
