Messenger bags are faster than backpacks and larger than pockets. A single sturdy messenger bag provides rapid access into a moderately sized holding space (consider what does not fit into pockets) with hands-free carry and full closure (preventing contents from slipping out).
Pros: Exceptional durability and solid all-around design.
Cons: Locking mechanism for top cover needs visual focus and is hard to use with one hand.
Waxed canvas frame is durable (for a fabric) with water resistance. Interior fabric is similarly durable and non-shedding. Full grain leather bottom is easy to clean with cut resistance. YKK zippers are reliable and smooth to operate. Wide and thick cotton sling is strong and comfortable with good weight distribution for reduced wear fatigue for the user. Metal D-rings (for connecting to the sling) are durable and have a special frame to prevent accidental separation from the sling connector. Top cover folds into place with two magnetic areas that are dampened by the canvas layer for silent closure. Made in USA with high quality assurance.
When moving items in and out of the bag frequently (ex. at an airport), for even quicker item access you can keep the top cover folded back and/or the main zipper open.
