Todd,
I'm not a "professional pack fitter" by any means. So, it's hard for me to say if it would fit you with certitude. That said, my guess is that you'd be in the right ballpark. There's no waist belt or sternum strap to worry about with this pack. I think the biggest issue for most people would be the two following questions: (a) Can I fit all my essential gear into a 1500 cubic inch pack? And, (b) is my gear light enough to ride comfortably?
If a person isn't already in the XUL range of <5 or 6 lbs, or ready to work to get to that place, then this pack wouldn't work. This would mean a small, light tarp, light down pieces, absolute minimal gear, one liter of water, and maybe two days of food max.
I'm new to the 1500ci pack myself and it's defiantly eye-opening. My go-to pack for the last few years has been the frameless, 3200ci Granite Gear Virga, which I've used to carry a base weight of 7.0 lbs of gear. Even though I'm really used to using a frameless pack, losing half the packing space is a big adjustment and it's forcing me to rethink items that I've been using for years. It's forcing me to think: How can I go smaller and lighter?
If you've always read posts about the GoLite Ion or looked at some of the cottage industry packs, but not been ready to spend $50+, then this pack might be for you. And, honestly, at $21 for this pack, even if I decide not to use this pack for backpacking, I figure I can stuff a beach towel in it or use it for day hikes when I travel abroad.
