Gregory backpack, size large, long spine. This is a vintage pack, not a lightweight one, but it is built to last a lifetime. I don't know the cc's but it accommodates a large load in two zippered access compartments. Zippers are very beefy like the rest of the pack. There are multiple exterior straps for extra gear.
It is purple in color, if that matters.
