I am thinking about these dimensions:
Foot: 34" (same as Ghost, 4" less than the Specialist)
Hip: 43" (same as Ghost, only 2" less than the Specialist)
Shoulder: 52" (3" less than the Specialist)
Straps: 2
The Specialist looks like it is 2" less than the Golite Ultra in girth along the whole bag. I have the Ultra and it is ultra roomy for me. The Golite has a loft of 2.5", and I would like this bag to have half the loft at 1.25".
How much down would you guess for that? The Edge at 0.75" has 6oz, and the Specialist at 1.75" has 9oz. (I also want effective down control – everyone seems to say add overfill to Nunatak stock bags for this).
