I am considering buying this sleeping bag (I have decided that down is not really vegetarian, yes I know I'm not eating it, so synthetics will have to do):
https://www.tauntonleisure.com/mountain-hardwear-women-039-s-laminina-z-fla...
According to the manufacturer:
EN Comfort -6 C
EN Limit -12 C
1.56 kg
Note that for the Laminina bags (the women's ones; I am only 5' 7") they go by the Comfort, not the Limit, so the Flame has the same insulation (200g, presumably per square metre) as the Lamina Z Torch and the old Hyperlamina Torch. The Hyperlamina Torch is rated to -9, -15 (despite having identical insulation) but is only 1.47kg; it does however only have a half zip and no DWR treatment. For some reason the bags got heavier going from Hyperlamina to Lamina Z, but being able to get a woman's bag makes up for some of the weight increase... the Hyperlamina is also much more expensive and rapidly disappearing!
How you rate this bag (just based on the temperature grades) for:
Alpine summer (in the valley - possibly overkill)
Alpine summer (at altitude)
Scottish winter
Alpine winter (presumably nowhere near enough?)?
I have a Neoair XTherm so it would probably be used with that. I have an old Lamina (rated to 2C I think but not EN) which is just over a kg but seems a really nicely made bag; I could always bring that as well if I needed all the warmth as it is a bit big for me really.
Would it be better to bump up to the Laminina Torch (2.01 kg) which seems excessive given that it only increases the insulation by 25% and goes to a -9 C, -15 C rating? Then at that point you can add only 40g to go to the mens Lamina Z Blaze, which has the same insulation (250g/m^2) but no EN rated temperature (just '-15', presumably -15F or -26C and bearing no resemblance to the EN temperatures) or the Lamina Z Bonfire (300 g/m^2) at 2.29kg (again no EN rating, just '-30' and again presumably -30F or -34C). So many confusing options!
Any other suggestions for lightweight synthetic bags that might be more/less suited (I realise I'm not sure exactly what I want to do with it, but probably Alpine summer at altitude, probably in a tent, is what I am aiming for, with winter Alpine being a bonus possibly with a filler bag)...
