WBBB and Nest underquilt
I tried this combo out on the trail a couple of weeks ago. After getting the tension correct on the suspension system it worked OK for me as long as the wind wasn't blowing. I had no issues with coverage in the foot or any other region. This combo did seem to be susceptible to wind coming from the side getting underneath the quilt and chilling things off. Perhaps I could have pitched my Maccat lower to block more of the wind.
