The JRB design under quilts all have draw cords that snug the ends of the under quilt up to the hammock, thus eliminating the need for and weight of extra draft stoppers.
Pan will the Mt Washington 3 convertible fit the BMBH well or is it to long?
I'll answer for Pan since he's busy writing soliloquy on another thread.
The MW3 Convertible is the same size as the MW3 and MW4. It should fit perfectly on the BMBH when in the full quilt mode.
To be honest, we have not tried the MW3 Short on the BMBH. It might require some inovative attachment rigging on the foot end.
You would still need a pad as well... The sleeves would compress the same as a quilt or bag does under your legs and feet....
We also believe that full length quilts are a far better option especially in bad weather...
The MW3C is all about options, for those that want them...
I posted our views on this on another thread, perhaps i'll copy it here since there are two threads working this discussion.
