So, currently, I hike with a Gregory Baltoro 65. I section hike with a group of buddies every year and have been slowly trying to get my total pack weight down. I started with over 50lbs and am now down to about 37 pounds. I don't think I'm after the super UL range or anything as I only hike once a year so I like to have some creature comforts. I am, however, interested in getting a lighter pack. The Baltoro is a GREAT pack that is REALLY comfortable and loaded with features. But with those features comes the weight. It weighs almost 6 pounds by itself! I've been looking at packs with about the same capacity as I have now but with much lighter weights. I've come across the Mariposa from Gossamer Gear and the Circuit from ULA. I've read some reviews on this forum about the two but from what I can tell they appear to be older. Some mention the lack of load lifters (which I love about my Gregory) on the Mariposa, but I see on their website it says they're standard. So I'm guessing the pack has just been redesigned since then. Also some have complained that the Mariposa isn't very comfortable at the heavier end of their specs (which is probably where I'll be) due to their shoulder strap design but I see where that has been redesigned as well.
So, what I'm looking for here is anyone who has the newer versions of either the Mariposa or the circuit or actually any other pack that would fit into the category I'm looking for. Any advice you provide, both positive and negative, would be very beneficial. Thanks for the help!
