I have a number of sleeping bags for different 'seasons'. I'm a cold sleeper generally, so I usually find that I use a higher rated bag than others - especially my partner, who seems to be able to sleep in mid-winter in a 2 season bag... :shock:
Anyway, I've never 'nested' bags, having always just used the next rating up, and gone for wearing all my clothes for extra warmth.
How do you know how much more warmth you'll get from nesting bags?
For instance, I have a range of Snugpak Softies:
Softie 3 - rated comfort 5C, low 0C
Softie 6 - rated comfort 0C, low -5C
Softie 10 - rated comfort -7C, low -12C
What theoretical ratings could I expect from nesting various combinations of these?
What extra warmth do you get from a silk liner?

I have a 3 night trip at Merthyr booked up for the first weekend in April - I plan to test my new Hennessy and am expecting cold weather!
