TOG is a rating system that measures warmth and calculates how quickly a fabric uses heat. It is the standard when choosing the appropriate sleeping bag for your baby depending on the ambient temperature in their nursery. We recommend a thicker tog during cooler months and a thinner size during warmer months.
At 1.0 TOG, it's the ideal warmth year-round.
