Grayman™ Series: Plan-B™

civilian lab® edition

light go-bag sling pack

Being jammed in confined spaces for hours is an unfortunate part of the business for many professionals we serve. Whether it’s a military unit in a personnel carrier, a pilot in a cockpit, drivers in a HumVee, or a journalist in the back of a goat truck, they all have to bring their gear, and all may need to ‘relocate’ in a hurry. Slim shaped, for fast maneuvering in crowds, they can be stored in vehicles/lockers, and are quick to take on or off. They are also ambidextrous, and unlike others in this class, are actually comfortable to wear. The main padded strap is cocked at either the right or left lower corner, so the pad aligns ergonomically in the correct body-hugging direction. There is no slack, or gapping away from the body as is typical with similar single shoulder packs. The bag can be rotated to the chest for on-the-go access, and all pockets are designed to face the user in this mode on either the right or left side. This means the user can go from wearing the pack on his back, to driving a vehicle with it on his chest in just a few seconds. One-strap also makes shouldering a long-gun natural - unlike a regular backpack.

Very Nice bag, but differentReview by Matthew
I really like this bag, structured just like the regular tac plan b but less descrete as you see. Price is decent especially since I got it on Black Friday. I absolutely love the color!!! However the reason why I gave everything 5 stars except for the quality only 4, is the material used isn’t as strong as the tac line of Hazard 4 bags, but doesn’t mean it’s not strong enough to withstand normal wear n tear. I currently own 5 Hazard 4 bags and love them all, this new line I will enjoy using it while I go through the city adventures. I do recommend this bag, it looks great and will get many uses for time to come. (Posted on 12/3/2017)

Is the Grayman series made of the same Cordura as other Plan B’s? Seems maybe not as durable?
No the Greyman is not made of Cordura. Although it is made of a different material this does not take away the fact that is is a strong and sturdy bag.
Thank you for contacting us.

I am looking for a discrete way to transport an Ar style pistol, with the upper and lower separated. My upper is 20.5" long, will it fit?
The main compartment dimensions on the Plan-B Grayman include ~19.75' L. Since your upper is 20.5", it might be slightly too long for it. The fabric does have some give so if you angle it a little bit, you could try to make it fit that way. The other recommendation we could make is the Takedown as it's main compartment dimensions are 27.3".

Hope this helps!
