I currently own a Little Shop of Hammocks 50F Apex quilt, a Vesper 20F, a MHW Phantom Alpine -9 Mummy bag, and a Cumulus Alaska 1300 (-30/-40C ish).
The Vesper 20 is really more like a 32f/0C bag. It has about 12oz of 900FP down. I find the gap between the Phantom and Vesper a bit too big. The Vesper 20F is OK down to freezing-ish but really is most comfy down to about +5C.
A lot of the year where I live in the Okanagan (Interior BC, Canada), it is fairly mild and I think a true 20F quilt would get a lot of use most of the year, through our long shoulder seasons (Sept to November and March to May). And then I would also use it in the Canadian Rockies through June to August. For example, on the GDT.
I find the Phantom a bit heavy (almost 1kg) a lot of the time outside of valley bottom winter camping or higher elevation shoulder seasons, or for more climbing and ski touring trips.
I’m wondering if I should look at replacing the Vesper for a cottage quilt or if I keep it and add a 20F quilt. Am I asking too much of a 20F quilt for use from -6C/20F to 10C/50F? Or is that perfect? If so, would you suggest a zippered footbox or closed?
I prefer weight savings of closed and find that sticking a foot with the vesper isn’t hard, but versatility will be important if I want one quilt to span this whole range. I think if I keep the vesper I would definitely get a closed foot box for the 20F, and if I sell it probably a zipped one?
Do people find any drafts in the zipped footbox below freezing? I don’t really want to mess around with sticking a sock in the hole, but some manufacturers include a down plug to fill the hole (Little Shop of Hammocks). Does that work well? Why isn’t it more common?
I’m also open to a zipped hoodless bag like a Conundrum. Any thoughts on that?
Lastly, all the different options are pretty overwhelming. They all kind of seem the same. Are there significant differences between different 20F cottage quilts? The ones I’ve looked at are: EE, Katabatic, Hammock Gear, Zpacks, HMG, LSOH…
