Tog Rating:
The word tog stands for “Thermal Overall Grade” which measures the warmth of a duvet.
The tog ratings available in Ireland & the UK ranges from 4.5 tog to 15 tog.
It is worth remembering that a thicker duvet isn’t necessarily warmer, as the effectiveness of the insulation will depend on the type of filling used. And, certain synthetic materials can be heavier than natural fibres, but still offer a similar level of insulation. So, rather than weight or thickness, the tog rating really refers to a duvet’s overall effectiveness at trapping heat.
