The Mountain Hardwear Hueco 35 Backpack is up for any climbing adventure, whether you're heading up a big wall or to the gym. With a stowable rope strap and a zippered helmet pocket, the Hueco leaves plenty of room in the main compartment for gear, food, and clothes. There's also an internal hydration sleeve that doubles as a sleeve for electronic tablets and guide books. The reinforced grab handle makes it easy to get gear out of the large zippered top opening when you're hanging thousands of feet in the air. Mountain Hardwear built the Hueco 35 around the HardWave suspension system, which conforms to your back in order to distribute weight as evenly as possible. HardWear tarp, Ballistic nylon, and HD nylon fabrics make this pack surprisingly strong for how little it weighs. The Hueco also features carry loops for trekking poles and ice axes, two deep side pockets for big water bottles, and a zippered security pocket for your phone, wallet, and keys.
