TOG stands for ‘Thermal Overall Grade’, which is a unit of measurement used to calculate the thermal insulation of a product, usually in the textile industry. Our sleep garments are given a TOG rating according to the warmth they provide. Basically, the higher the TOG, the warmer the product.

To help parents understand which TOG values are right for differing room temperatures, a set of guidelines has been established as per below:

0.2 TOG – ideal for room temperatures between 24°C and 27°C
1.0 TOG – ideal for room temperatures between 20°C and 24°C
2.5 TOG – ideal for room temperatures between 16°C and 20°C
3.5 TOG – ideal for room temperatures below 16°C
