What sort of duvet tog would be suitable for camping in this country (SW) at this time of year? I went into the loft to get one and it's 13.5 tog so I need to go out and buy a cheap one from the market. Don't want to be too hot or too cold.
Would a combi be suitable? I believe it comes with 2 duvets, e.g. a 4.5 Tog and a 7.5 Tog, You can use either on its own, or combined together using poppers in the corners for a warmer 12 Tog duvet.
