The Evilution has tuck away shoulder straps and a removable waist belt, so it moves seamlessly from airport to crag. No problem spotting in on the luggage carousel at the airport, and its teardrop shape, full back panel and ergonomically-designed suspension means it carries like a dream. The full double-zipper allows easy access to all your cragging stuff, and an internal mesh organizer keeps the small bits from getting lost. And it's made with PVC-free truck tarp fabric, so you know its bomber.
