What is a TOG rating?

TOG stands for ‘Thermal Overall Grade’ which simply provides a measure of warmth; the higher the number, the warmer the garment.  You may have noticed that our sleeping bags are not TOG rated like most other brands but instead have a temperature guide.  This is because Merino Wool has unique thermo-regulating properties that respond to the environment, keeping your baby warm when it’s cold, and cool when it’s hot.  This is also the reason why our regular sleeping bag is suitable for use over all seasons (effectively the TOG rating changes depending on the external temperature), whereas with TOG rated garments you are most likely to need various weights to cater for different temperatures.
