What is Tog on Baby Sleep Bags?
Mar 12, 2015
- 4.5 tog - Lightweight summer duvet
- 9.0 - 10.5 tog – Spring/autumn duvet
- 12.0 - 13.5 tog – winter weight duvet
- 0.5 tog = for hot weather / warm nursery 24-27 degrees
- 1.0 Tog = for autumn/spring weather in temperatures of 20-24 degrees
- 2.5 - 3.5 Tog = ideal for cooler nursery temperatures of 16-20 degrees
You'll also need to dress baby appropriately under that sleeping bag. So in cooler temperatures, you're going to need a singlet, and warm pyjamas under that sleep bag, while in warmer temperatures you'll need cooler pyjamas. All those extra layers add up to extra Togs, or thermal insulation. And on really hot nights, your baby will probably just be wearing a nappy and a singlet under a cool sleep bag, which means a lower Tog.
Nerd alert! Here's a fun fact: the word TOG is short for Shirley Togmetre, which is the actual name for the measurement. The British Cotton Industry Research Association in Manchester, England, was known as the Shirley Institute and it was they who came up with the TOG rating. So next time you're shopping for doonas, or baby sleep bags, you can stroke your chin knowledgeably and say, "I believe this rates a 1.5 on the Shirley Togmetre." Or not, of course. Entirely up to you. And don't ask me who Shirley was. I don't know.
