Big fan of the Gregory lines, this is no exception. Wanted to downsize to Baltoro, but ended up going with Osprey. Gregory's are still burlier though, IMO. Figured that 80 liters is too much for most trips in Colorado, can fit up to 10-15 days worth of stuff in a 70 liter, and favorted the Aether 70 when compared to Baltoro, plus got a screamin deal. If I ever pony up for Denali, this will be my pack and its on clearance now. This outdoor gear is like electronics, you blink and cutting edge stuff will be in outlets within a couple months.
