I also was disappointed in the performance of the V Luxe. Everything I could find online indicated it should be fine well below freezing.

I’m now vacillating and requesting my underquilt order be changed to a zero degree version . I started to run scenarios in my head and for every nighttime low up to 40 degrees, I didn’t think a zero degree UQ would be too warm. (Of course I don’t know that from experience, yet .). Also a factor for me is not having to carry multiple bottom insulation layers until the zero degree UQ is no longer sufficient for the overnight low. Right now I struggle more with bulk and being able to fit everything I need into a pack or pulk, more than I struggle with weight. (Hell, I’m always carrying 20 more pounds of me than I need to.)
