The B4 SWIFT makes a perfect VFR Flight Bag with room for one or two headsets, an iPad, a handheld radio, and organization for all the little tech accessories. Remove the 4-inch Center Section and end up with the B-zero SLIM. Two different bags for the price of one.


The B4 SWIFT is often recommended as the ideal VFR flight bag. It’s designed to hold one or two full-sized headsets plus a handful of charts, and/or an iPad, plus all the small stuff you’ll want along for the ride. It also serves as an unbeatable carry-on personal bag when traveling on commercial flights, or just as a terrific daily bag for a wide variety of personal and professional uses. The B4 consists of the POCKET CAP FRONT, CENTER SECTION 4, FLAT CAP REAR, along with two Side Pockets, Alpha and Charlie.

The CS4 provides, that’s right, four inches of storage depth, but keep in mind that there is also two thin flat storage areas BETWEEN the three modules. (Remember, it is a soft bag so it can expand slightly in every direction.)  Keep in mind also that you can add any other Center Section to the B4 (like zip a CS2 in between the CS4 and the FCR) to add more storage on certain days.  Any FLEX System module can zip onto any other FLEX System module.

This configuration will very commonly be used to carry two full-sized aviation headsets of any brand.  (There is a nice, slightly-tricky way place two large headsets – like the Lightspeed Zulu.2 or DC ONE-X – inside this space. Just “intertwine” the ear cups in opposite directions. It’s really nice to fit two headsets of any kind in such a relatively small space.)

There is a specially-designed pocket on top of the CS4 to hold Sunglasses and their case.

A small collection of charts or flight docs can go in the space between the CS4 and either of the End Caps. A 13″ Ultrabook or MacBook Pro can also fit into this “in between” space, and the iPad (or other tablet) can go in the main pocket on the FLAT CAP REAR

The B4 SWIFT also works amazingly well as a daily personal bag and/or as a commercial carry-on bag. A 13″ laptop plus a load of documentation plus an iPad, plus all the small stuff like cables, adapters and support stuff for all your technology, your digital camera, snacks, etc – all of this fits easily in this bag. Even your noise-reduction headset for those long flights.


Interior of CS4: 13.5″ tall, 10.0″ wide, 4.0 inches deep. (34cm x 25cm x 10.2cm)

Exterior of entire bag: 14.0″ tall, 10.5″ wide, 6.5″ deep. (36cm x 27cm x 16.5cm)

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.
