What is a TOG rating?

Published in Sleeping Bag
TOG stands for Thermal Overall Grade. It is a unit of measurement used to calculate the thermal insulation of a product, commonly used in the textile industry (quilts, duvets, and comforters). It indicates the degree of warmth you should expect from your swaddler. The higher the TOG, the warmer the garment. To help caregivers understand what TOG fits your needs, we have recommended guidelines for each TOG. Please see the “What To Wear Under Your Sleep Bag” chart.
