TOG is an international standard for warmth and thermal effectiveness. A TOG is the unit measurement of thermal resistance and is used to estimate warmth.
TOG may be used as a general guide to help parents choose the appropriate level of warmth for their baby’s zzZipMe Sack for their environment.
Each baby is unique and parents should touch and feel their baby’s neck or tummy to ensure baby is not too warm or too cold. If baby is sweaty a layer should be removed. If baby feels too cool, an additional layer may be added under the zzZipMe Sack.
