The Gregory Z65 Backpack is a versatile, comfortable, and extremely lightweight hauler that is perfect for the trail or heading to the crag. With its plethora of pockets, this pack can easily store all your climbing gear or the equipment you need for a week of solitude and mountain air. Its CrossFlo suspension system provides airflow to help keep you cool in warmer weather without sacrificing the ability to comfortably shoulder a full load. The spring steel bar curves with a wire frame directly into the lumbar pad in order to ensure the load's entire weight transfers to your hips. Gregory covered the shoulder straps and waist belt with ventilated EVA foam to help minimize discomfort and maximize cooling airflow for warmer days on the trail. This top loader also features a U zipper side access so you can whip out an extra layer at a moment's notice. The front bucket pocket can stash that extra layer and leave it accessible and within reach at all times. The floating top lid is removable, and the integrated rain cover should protect your gear in case some black clouds unexpectedly float over your routes. Gregory also added an interior hydration sleeve with a hose port, a zippered front pocket for smaller items, two external stretch pockets for water bottles, and dual waist belt pockets for sunscreen, lip balm, and snacks for the trail. There are also hideaway loops for ice axes or trekking poles and compression straps at the bottom and sides to keep your ride smooth when you're not carrying a full load.
