Defense Courier™

laptop-messenger bag

A true messenger in concept, it stays very flat when carrying loads like a laptop, but its ingenious construction allows it to square-out to accept a huge load-out. The similarities to its conventional cousins end there. The full suite of tactical/professional features included make it a genuine work-bag. The shoulder strap is sewn directy to the sides with huge x-stitches so there is no hardware to break under heavy loads. The strap has a thick, comfortable pad with modular loops for attaching pouches, etc. and a quick-release buckle with lock for emergency drops. The webbing used throughout the bag is a class-leading diving-tank strapping that is stiff yet soft on skin. The front surface under the flap is covered in modular (MOLLE-compliant) webbing to load-out numerous pouches, etc., but keep them hidden/protected under the unassuming flap. The flap-straps compresses bulk with oversized lock-buckles, and the front has a large loop-fastener area which also fits our available i.d. window patch. The patch can be secured to the flap w/ our Civilian® Rewind™ cable gear retractor. There is a large zippered pocket on the flap and the flap itself unzips in the front, to allow access to the main cargo bay without opening the buckles!

There is also modular webbing on both sides of the bag for attaching side-pouches (for water bottles, etc.) and some more next to the rubberized top-handle. The interior of the main bay is covered with 4 stuff-pockets for magazines, bottles, first-aid kit, etc. The under-flap is a large, clear, weather-proof window for maps/documents that can be quickly consulted on the go. The interior area behind the front flap also contains a zipped organizer panel for all the pens, flash-drives, knives, etc. that most users would ever need to carry. There is also a heavily padded laptop sleeve carrier lined in our unique quited soft fabric, and closed with its own adjustable strap (up to 15" PC.) The front of the laptop area is a large loop-fastener to accomodate many patches and organizers such as our law-enforcement-specific Stick-Up™ holster for any auto-pistol (sold separately). For airport travel, the bag's back can be mounted onto rolling luggage handles via a webbing strip, that can also support belt-mount-type accessories or be used as an additional handle.

The design is finished off with two flat-pockets at the ends (of different heights) for quick access to longer items. Silent YKK zippers w/ pullers that are user-serviceable in the field are used throughout. The two flap-slash zipper-pullers are even marked with rubber sleeves for tactile location even at night. The color matching on all the hardware, Cordura® fabric, and trim is excellent, and from a functional and aesthetic perspective. The Defense Courier™ is an amazing value compared with messenger bags in any market.

Good bag, needs some revisions.Review by Takeapicture
I searched and search for a great laptop bag. Stumbled upon this guy. Great bag, has modular abilities and hold everything I want and more. I have had 2 issues. The buckle on the shoulder strap "creaks" when walking and the shoulder pad slides off your shoulder because it has no grip on it. I would love to see those changed and we would be the best bag in the world. (Posted on 11/18/2016)

High Quality Product-purchase with 100% confidence. Best layout for a messenger yet. Obviously designed by a quiet professional. Plenty of pockets for all your gear. (Posted on 5/8/2015)
AwesomeReview by Dave
Purchased bag to replace an old computer bag to carry a large laptop and supporting documents for work. The bag is constructed well and holds everything I need for work and more. The strap is well padded and no issues carrying the bag fully loaded (Posted on 7/24/2014)
I like it.Review by Ray
I had been eyeing this pack for about a year, while trying to find more reviews on it but are pretty limited. Tho I did find one youtube video showing that there was a problem with the strap's buckle, but I just figured it was a defective buckle. And so far I was right, no problem with the any part of the packs. Have had it for a few weeks now, fits my 15" laptop nice and snug and I just love how casual it looks while remaining "tactical" (Posted on 12/25/2012)

Does the back panel have a sleeve to slide over standard luggage handles (to secure bag to luggage when traveling through the airport)?
Yes, the back of this messenger bag does have the retain webbings to help you hook the bag onto any luggage handle.

What is the purpose of the velcro opening in the bottom of the admin pocket?
You may be the first customer ever discovered this secret pocket (or at least the first to contact us about it.) During product development years ago, our head designer was not happy about the organizer panel being a bit floppy, so he decided to add an extra velcro closure to add stability as well as creating a secret compartment to hide important document or money. You can also insert extra foam there for extra padding.
