BTW, Backpackinglight just did some comparative tests of frameless packs. They used the same pack and in one they put the pad in as a tube around the packs perimeter and in the other they folded the pad and placed it at the back panel. The folded pad in the back panel supported the pack more than the tube method.
It's interesting that they reached those results. I think the last time I read up on this at BPL, most guys rolled their pad around the perimeter. I haven't read the article so I'm not sure if they tried to explain scientifically which way was best or just used anecdotal evidence.
When you say you fold the pad, I presume you are just folding it in half and placing it on the back panel? Or do you fold it in an "L" shape with one part flat on your back and the other part sitting on the bottom of the pack--so the rest of your gear goes on top of that part and "anchors" down the pad? Just curious about what approach you take.
I'm hoping to get out to play today. I might pretend I'm going backpacking and load up my gear in the Virga and play around a bit to see what works.
Thanks to all!
