After much research, price comparison and deciding I need a "chick" bag, I finally found out what I was looking for with Women's REI Grand Tour Travel Pack.
Here the down and dirty of my new pack:
Detachable day pack with hydration pocket and hose port (now I can sell my old packs on craigslist, and have more money for my trip)
66.5 liter capacity
Fairly light at 4 lbs. 8 oz. - but we will see after I pack
Adjustable suspension to customize fit
Extra compression straps above shoulders help secure your load
Lots of compartments both inside and outside (6 pockets + 2 main compartments)
Lash points to attach gear and compression straps to snug loads
Bottom area can be sectioned off from the rest and can hold a shoes and dirty clothes - or someday a sleeping bag
All straps can be zipped up for storage on planes, buses and cars (see pic).
Best part it was only $130 (on sale from $189) and in mallard a fun green color.
Now it's time to try it out and see if I like it as much when it's on my back full of all my stuff :) Or should I say half of what I plan on bringing if I follow everyone else's
advice.
