July/early August I use a 20° rated EE quilt, late August/ early Sept I use a WM terralite. I do have a SG 15° bag but that is an October bag for me in that country. If they are backpack hunts, I go as light as I can knowing that I'm not leaving home without puffy pants and a puffy jacket so you have that available should temps cool off significantly. Personally, I'd rather add layers than buy a single bag for all conditions. I can't stand being hot when I sleep.Doing late July/early August in Northern British Columbia next year and late August/early September in NWT fir 26.
Decided on Western Mountaineering. Still grinding on which one.
I would say it's more personal preference than anything. The first one I had was more of a lite weight silk style as I had more early season hunts. The one I have now is cotton. I don't mind eitherAny recommendations on the bag liners?
