Thule's owned the cargo-carrying game for eons, but it's recently turned its attention to the human-powered packing arena, and the results have been killer. The new Stir Men's Hiking Pack is a prime example with its top-access design that combines a cinch-down opening, top storm flap, and internal zip to keep all your gear locked down and well-organized. Equally impressive is the StormGuard design, which features a partial hideaway rain cover that teams up with the Stir's waterproof bottom to create a waterproof package that's still usable, even when it's covered up.The Stir is as customizable as it is well designed, with a sliding backpanel to fit different torso sizes and a removable hip belt and sternum strap that give it a more streamlined look for around-town use. A side zipper provides easy access to buried layers, and pockets at the shoulder strap, front, side, and top supply convenient spots to stash your phone, water, rain shell, and snacks. There's even a dual ice axe/trekking pole carrying system, so you can be fully prepared if things start to get technical.
