Take it from us, the Arc’Teryx Miura 30 backpack means business! Arc’Teryx, originating in North Vancouver, Canada, has been making focused designs with the highest performing materials since 1989. Each pack is critically scrutinized and placed through the ringer, and it shows. We’ve used our Miura as a commuter pack for both cycling and running home from work, and this 30-liter convertible pack is large enough to hold everything from climbing gear to daily commuting gear. The feature we like the best is the roll-top that allows easy access to all our stuff. We’re convinced this pack would survive Armageddon! Buy em here.
