Its a Duffel Bag! A 23 L bag that has a 10" diamter, and is 18" long. Its made from Mil-Spec highly abrasive resistent 1000d Cordura with a water resistant coating, a Mil-Spec zipper chain self reparing zipper, Mil-Spec 17337 solution died webbing, and a high viz orange 400d interior. Theres a 10" wide, 6 inch deep external pocket for phones, keys and other quick access items. 
 
 This isnt a cutting edge bag design, but it is an overbuilt, daily use product that can handle an excessive amount of abuse. Its also 100% made in the USA (the 400d packcloth that is not made in the USA but is berry compliant) 
 
The Straps are made of 17337 webbing which is more flexible than some others (its what we use on the rear body of our slings). This flexability means the shoulder strap is comfortable even without a pad. The hand straps can also be worn by most people as a backback style.
 
Choose to add a 4" velcro section on the exterior pocket.
