A tog measurement is a European warmth rating: the higher the tog, the warmer the product. Cotton baby sleeping bags such as Grobag or Ergopouch are generally available in three tog ratings; 0.2 - 0.5 Tog for temperatures above 26 degrees, 1.0 Tog for temperatures between 21 and 25 degrees and 2.5 Tog for temperatures 16-20 degrees. Some brands also offer 3.5 Tog Bags for temperatures 14-16 degrees.
Please note: A number of external factors determine the tog rating of the sleeping bag that should be used. These include the quantity of clothing the baby is wearing, the temperature of the infant’s bedroom, the baby’s health and the amount of bedding necessary to keep an individual infant warm – this may vary as it does for adults.
Check your baby regularly to ensure they do not overheat.
