Can it go -30 degrees celcius?
I know it's already been said that you can wear it in neg temps, but how much layering (specifically) would i need for that temperature?
And i know it has a down fill of 550 - but does anyone know how much down is actually in there (in grams) because it looks quite thin to me in the pictures?
Thanks
