What TOG Do You Need？

What is TOG ？

TOG (or Thermal Overall Grade) 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 your nursery. We recommend a heavier TOG during cooler months and a lighter one during warmer months.

This sleep bag is a 1.0 TOG, perfect for 21 to 23 °C or 69 to 73 °F.
