Messenger Bags

Weatherproof Roll Top Bags

Mission Workshop messenger bags feature a weatherproof roll top main compartment which can be used in either the "roll top" mode, or in the traditional "flap down" configuration. The padded shoulder strap includes custom aluminum hardware that allows for one-handed "on the fly" strap adjustment. All shoulder straps are easily swappable for left or right shoulder configurations.

Made in USA with a lifetime warranty.
