The Gorge Pack features a large, funnel shaped opening which loads easily and quickly secures via drawstring closure. A full length, heavy duty zipper allows you quick and easy access, even to items buried in the bottom. Handy outside pockets easily handle loose items such as chalk, lunch or guidebooks. The thermoformed shoulder straps, hip belt and back panel all combine to provide a comfortable and supportive suspension system. Pack comfortably fits my rope, two pairs of shoes, trad rack, slings and beaners, belay/descent gear, helmet, water, food, and guide book. It has two exterior daisy chains to attatch more stuff if you like and a cover in case you want to tote an extra rope. There is also a hidden inclement weather hood that covers the top of the bag. The bag is designed with a "stand up bottom" that keeps the pack upright even when empty. This is the last pack you will ever have to buy. You can't beat it for design, comfort, and durability. Size is 3000 cubic inches.
