different thermal measurements for sleep gear

[fish]

I was looking for this info as i was wondering what a 13.5 tog duvet equates to in sleeping bags and under quilts for hammocks,as i have ordered a down filled duvet at 13.5 tog to make into a big hammock under quilt.


1 season, Summer: 15ºC to 8ºC / 3 to 5 TOG
2 season, Spring/Autumn: 10ºC to 0ºC / 5 to 8 TOG
3/4 season Winter: 3ºC to -10ºC / 7 to 10 TOG
5 season Mountain: -5ºC to -20ºC / 9 to 12 TOG
Polar/High mountain: -15ºC to -40ºC / 11 to 16+ TOG

That's really interesting, I had never seen these comparisons. thank you for sharing T^

[butchthedog]

yes, agree with BJ. It's worthwhile knowing what the tog value relates to in Centigrade for DIY Under blanket making

I've not used an under quilt, is it used with a sleeping mat or instead of a sleeping mat?

[fish]

instead of and it really makes a difference,i made one that turned out too small and it is very warm.

[Wardy]

Is it so the mat is not crushed or moved during the night I suppose

Just a thought - won't down be too compressible?

[fish]

no not too compressable it will compress down in a compression sack,once out a quick shake and the jobs a goodun.

An underquilt is'nt compressed - it hangs under the hammock.
