John, if Nick doesn't go for the 450 quilt, I might be interested too. Out of interest, how do you find the quilt, what kind of temp is it comfortable to? ThanksJohnClimber wrote: ↑Sat Jan 15, 2022 11:10 pmAs a side sleeper who twists and turns in the night, the cold bum is the problem to me at times.Bearbonesnorm wrote: ↑Sat Jan 15, 2022 10:57 am Out of interest john, what is it that's drawn you to a bag away from a quilt?
This bag is an experiment to see how it works (Sam talks highly of it) and will be used with my 250 quilt as an over quilt in colder weathers, maybe the 450 if it's not as warm as I hope

Thanks, and noted
I've found it's been good down to around 2 degrees and I sleep in Long John's merino socks, Helly Hanson top and if colder a down jacket too.
If it's any colder ir if I'm under a tarp rather than a tent at these temps I tend to double bag it with my 250 quilt that I'm keeping

Are you sleeping in a different room to it? I've had my 150 down to less than thatI've found it's been good down to around 2 degrees

Sorry I got mistaken, I'm not as hard as you I've had my 250 down to 2 degrees, but I needed a down jacket too.Bearbonesnorm wrote: ↑Wed Jan 26, 2022 7:52 pmAre you sleeping in a different room to it? I've had my 150 down to less than thatI've found it's been good down to around 2 degrees![]()
The 450 can go lower than that, but I've never really camped may times below freezing, because I'm a wimp

I do think it depends on whether you are a warm or cold sleeper - Cath's been down to -6 with the 350 with no problem. I find the Cumulus ratings to be pretty accurate (for me).Bearbonesnorm wrote: ↑Wed Jan 26, 2022 9:33 pmThat's more like itI've had my 250 down to 2 degrees, but I needed a down jacket too.I reckon a 450 is probably good to around -6 with appropriate mat.
