I'm happy with my Chacabuco/32L and can't even remember how long ago I bought it.

Use it for: - city use, - "pack dad" use (carry extra jackets for my children), - day hikes, - carry on bag - ski bag (carry stuff on downhill ski trips)

Have thought about trying to do an UL overnight backpack trip with it for kicks.

Have taken it back once to Patagonia for free repairs, and another time for a free replacement of some plastic gizmo that fell off.

Nit picking: - The elastic shockcord doesn't work right for me - it seems more cosmetic and doesn't really cover the rare use case of wanting to, say, quickly strap on some sandals on the back and know they don't fall off (they did..).

I've used the shockcord netting to hold my bike lock... But then, I've found that the Chacabuco was not my bike bag of choice after a couple trips. Replaced it with a hand-me-down CamelPack for exploration and panniers for daily commutes.
