I've got :
thermal base layer, 95% merino socks, prologic max 5 thermo suit, hat, gloves, neck scarf.
snugpak 4 season bag, snugpak jungle thermal blanket, ngt hot water bottle
Got a bio ethanol(ventilated but supposed to be odourless) to burn in trangia stove if it's to wet to use gas stove outside. Did look at the candle heater but candles still produce carbon monoxide
This is the main reason I was looking for some kind of heater as it can be the middle of the summer but the other half still wants the heating on.
