So, thanks for all the replies on the first thread. I was trying to see what there is out there these days,. in a market, that seems to be passed over quite a bit.
Short of old design travel packs from Mei and the like, or 800 dollar custom packs by Mchale, or make your own, there really isn't much out there, specially, if you wear a size large. I couldn't find length dimensions for things like a large Osprey talon 44 or HMG wind rider, so I don't know if what people suggested was for sm, med, or large. It looked like the GG Gorilla size sm and med are 22" or shorter, but the large appears to be 24" tall.
The other thing that might be an important consideration, for people wanting a world travel pack, that is capable of hauling a couple of gallons of water and gear, is going through customs. Personally, I would prefer a panel loader, so I didn't have to have a yard sale every time I went through customs.
It seems to me that with everything getting smaller and lighter these days, that someone would come up with a really well designed carry on sized, panel loading pack, with an internal frame, that is made from durable lightweight fabric and didn't set you back 800 bucks.
