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. 0.5 TOG: 23 - 26C / 74 - 78F 1.0 TOG: 21 - 23C / 69 - 73F 2.5 TOG: 16 - 20C / 61 - 68F Exterior: 97% Rayon from Bamboo, 3% Spandex Filling: 100% Polyester
