Arc'teryx Bora 90:
The streamlined Bora 90 spans that gray zone all outdoor enthusiasts encounter when they're stuck between needing a generous mid-sized and a moderate large-volume pack. It's excellent for those multi-day outings when you want to be prepared, especially during winter mountaineering outings, but it's not too much to carry on weekend cragging trips. Like the smaller Bora 70, the 90 features a practical side zipper for quick access to the main compartment, so you don't have to burrow to find important stuff at the bottom of your pack. The detachable back pocket features a daisy chain and can be hinged away from the pack to provide ventilation for wet gear.
