Keep  in mind that the bag material is flexible, so the size of the  interior  storage may be able to "stretch" out just a bit in one  direction or  another. Also keep in mind that over-stuffing your bag can  cause seam  or material failure, and this is not covered by warranty.
Empty Weight:
9.8 lbs.  (4.47 kg)
Total Number of Available Flex System Side Pockets:
Six. (Two FLEX-Mount side pocket stations on the CS5, and four on the CS11.)
Modular Expansion Capability:
Unlimited. You  can add any of the other FLEX System modules to this  bag, in any  order, to make a bag as big or as small as you need on any  given day.
 NOTE:  BOTH THE CS5 AND THE CS2 OPEN TO THE REAR.
  Every module in the FLEX System has a front surface and a rear surface.    All of the modules are one-directional by necessity.  The original   assumption was that the CS5 (or the CS2) would be added onto the back of   a CS4 for more storage.  The CS4 opens to the front, and so therefore   the CS5 and the CS2 open to the rear.  Thus, in the case of the B18,  you  should know that the PCF (Pocket Cap Front) will attach to the   non-opening side of either the CS5 or CS2, and the FCR (Flat Cap Rear)   will attach to the rear panel of the CS5 or CS2 which is the panel that   opens and closes to give access to the contents of the CS5 and CS2. The   Main Compartments of both the CS2 and CS11 have locking zipper  sliders.   The Main Compartment of the CS5 DOES NOT YET HAVE locking  zipper  sliders. It will soon.
Embroidery Options:
The top front pocket cover of the POCKET CAP FRONT module can be removed to make it easy to add custom embroidery.
  Also, the pocket on the very top of the CS11 can be removed in the same   way to add embroidery. Just remove either of these pocket covers and   hand them directly to your current embroidery provider.  (We don't offer   any embroidery service.)
Description
Designed primarily  for aviators who need a Pilot Flight Bag to pack  multiple overnight  items, such as clothes, shoes, coolers, etc., the B18  HANGAR fits the  bill when maximum space is required. Also excellent for  those in the  Law Enforcement and Emergency Medical field.
 
 The B18 is 13.5" x  10.5" x 22" with interior storage capacity of 18  inches. (And  remember, it is a soft bag so it can expand slightly in  every  direction.)
 
 The B18 HANGAR is comprised of the POCKET CAP  FRONT, CENTER SECTION 5,  CENTER SECTION 11, CENTER SECTION 2, FLAT CAP  REAR, SIDE POCKET ALPHA  (Large Radio/Water Bottle Pocket), SIDE POCKET  BRAVO (Small Radio  Pocket), SIDE POCKET CHARLIE (Pen Pocket), and SIDE  POCKET DELTA (Double  Pocket).  It also includes the MH and SS.  It does  NOT include a SLIM  HANDLE KIT.  If you ever think you'd like to remove  the all of the  Center Sections and zip just the two End Caps together  to make the B0  SLIM, you'll need to make sure you also order an SLIM HANDLE KIT.
 
  Storage on the B18 starts with the POCKET CAP FRONT: The POCKET CAP   FRONT acts like the "hub" for your entire FLEX System. No matter which   configuration you carry you'll be attaching the POCKET CAP FRONT to one   end of your bag. And it's the "hub" because it holds all the important   small stuff and tech stuff and personal stuff that you want with you no   matter what. If you change configurations, you'll always move the  POCKET  CAP FRONT to the new configuration which means you'll always  have all  this key stuff with you, without any repacking or reloading.
PCF:    The POCKET CAP FRONT module offers a variety of pockets  organized  into three "main" pockets and six "secondary" pockets for a  total of  nine small pockets on the front panel. In these nine pockets  you'll  store all the cords, cables, chargers, batteries, stylus, memory  cards,  USB drives, etc, for all your electronic gear. All these  important  items will finally be separated and organized like you've  always  wanted. In addition, you'll have room for your flight timer, fuel   testers, E6B, flashlights, compact portable GPS, etc. Not to mention   space for your wallet, keys, cellphone, business cards, multi-tool,   glasses, pens, markers, and things like Ibuprofen, Chapstick, bandaids,   etc, and even your digital camera. There is also a flat half-height  slip  pocket on the inner surface of the module where you can stow an   important document or two like a copy of your medical or your passport.
CS5:    Next, comes the CS5 (5-inch Center Section), which will  commonly be  used to hold anything from a bunch of flight documents, to a  couple of  changes of clothes, to your lunch.  The CS4 also comes with a  divider  shelf which serves to separate the compartment if necessary,  which  really comes in handy if you want to carry two more full-sized   headsets.  You can instead fit 13” laptops and a small collection of   documents.  Many, but not all, 14" laptops will also fit. - But no 15"   laptops will fit. The CS5 has a really versatile dual-access feature.   First, you get full top-access. You can unzip just the top of the bag to   give access to your stuff right through the top of the bag. And then   when you need, everything can also be accessed by unzipping the entire   front panel all the way down to the bottom, giving access to the entire   gray interior of the CS5. The Main Compartment of the CS5 DOES NOT YET   HAVE locking zipper sliders. It will soon. On top of the bag is a  pocket  for sunglasses. The other key thing about the CS5 is that it has  two  FLEX-Mount Side Pocket stations, one on each side, for attaching  the two  included side pockets. You can, of course, also trade out the  side  pockets any time you like later on.
 
 The CENTER SECTION 11  offers a full 11 inches of interior storage and  swallows up multiple  day's worth of clothes. In addition to clothes, the  CS11 will carry a  small cooler or helmet. The CS11 comes with two  vertical divider  shelves. If needed, you can organize a 13" laptop,  documents, and  clipboards.  The Main Compartment of the CS11 has locking  zipper  sliders. The top of the CS11 carries a 8 inches square pocket  along  with double side pocket mounting stations. The CS11 can be  installed  over the upright handles of our folding cart using the zipper  access  found on one side.
 
 The CENTER SECTION 2 offers two inches of  storage and easily carries 13"  laptops, some 14" laptops, tablets as  well as documents, folders,  clipboards, etc.  The Main Compartment of  the CS2 has locking zipper  sliders.   NOTE:  Many of  the photos show a small one-inch webbing strap going across  the very  top of the module. This strap has been removed. It is no  longer part of  the bag.  We removed the strap because it was left over  from the  pre-FLEX days and it is no longer needed as a secondary  handle. We just  didn't want to go through all the trouble of reshooting  all the photos  just for this minor change.  We hope you understand.
 
  The FLAT CAP REAR module offers two flat pockets on the outside, and  one  flat half-height slip pocket on the inner surface of the module.  The  primary outer pocket is accessed from the top and has a cover flap  that  is secured with Velcro. This where you'll likely store your iPad  (as  long as it's not in a thick case), or a manilla folder or two for  some  documents, or a magazine. There is a second flat panel that covers   two-thirds of the outside of the main panel that is broken into two   halves - an upper panel and a lower panel. By default, the bottom edge   of the upper panel is "tucked" into the top edge of the lower panel.    This allows both panels to act together as a single slip pocket that   works great for sticking a boarding pass or other simple paperwork here.    If the top panel is "untucked" from the bottom panel, this allows the   telescoping tubes of a suitcase or folding cart to pass through and  the  panel serves to secure your bag to those tubes (especially when  this  FLAT CAP REAR is attached to other modules to form bigger bags  like the  B2 COMPUTE, B4 SWIFT or the B7 FLIGHT).  Then, when you're  done putting  your BrightLine Bag on top of your suitcase, you can just  "tuck" the top  panel back into the bottom panel and it becomes a slip  pocket again.
Keep in mind that the modules included in the B18  can be assembled in  any order.  You can also remove modules and  reassemble the remaining  modules into a smaller bag.  Or can combine  other FLEX System modules.   Any FLEX System module can be zipped onto  any other FLEX System module.
SIDE POCKET ALPHA is often called  the "Radio Pocket".  It will hold  any, repeat - ANY, handheld radio.   And the top flap is such that the  antenna can just stick right out the  side.  In addition, the SPA is  great for holding a water bottle.  The  front face of the pocket has an  expansion zipper to allow bottles up  to 20 ounces. To carry larger water  bottles, please select a Side  Pocket Echo instead.
SIDE POCKET BRAVO has two half-height  compartments.  The upper  compartment has a fold-over cover flap and it  was originally designed  for the short hand-held radios.  The lower  compartment is closed with a  zipper and it is great for holding small  items like spare batteries or  ear plugs, etc.
SIDE POCKET CHARLIE  is often called the "Pen Pocket".  I has three  pen slots on the outer  surface plus a zippered pouch that has room for  pens, marker,  highlighter, spare reading glasses, etc.  Of course, many  people will  put completely different things in there besides pens. It's a  great  pocket many different purposes.
SIDE POCKET DELTA is a  "double-wide" pocket which mounts on two  adjacent FLEX-mount side  pocket stations.  The two mounting stations can  be found either on a  CS11, or they can even be found on two adjacent  modules and the Side  Pocket Delta can bridge across the gap between the  two modules. 
The B18 HANGAR comes with a MAIN HANDLE and a SHOULDER STRAP.
