This is basically a large messenger bag with a unique strap system that allows you to wear it like a backpack. If you prefer you can carry it like a traditional messenger bag. This bag also differs from most messenger bags in that it has many compartments and pockets to organize all your gear.

The bag is in very good condition overall, just dusty and a bit wrinkled from sitting in storage in a closet for 20 years.
Asking $20 cash only. Must include phone number in your reply. Thanks!
