Question Insulation question for "Just in case" half sack

[Moondog55]

I stuffed up the home sewn half bag. Got it almost finished when I realised I was using 100GSM Thinsulate and not the UL LiteLoft.
So I just bought a S2S Traveller2 Large on sale. I can use it as a summer bushwalking bag too being rated comfortable at around 5C

I've found your new suit @Moondog55 . Can't make my mind up between the yellow or the red.

Red ones are always warmer
