Brightline's mammoth B18 Hangar bag consists of the Pocket Cap Front (PCF), Center Section 5 (CS5), Center Section 11 (CS11), Center Section 2 (CS2), Flat Cap Rear (FCR), 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) modules from Brightline's popular FLEX line of flight bags. The PCF features 3 primary pockets - each with a pair of secondary pockets - for a total of 9 storage compartments for accessories and smaller items. The FCR has two exterior pockets: a half-height pocket with a top Velcro closure (perfect for a tablet) and a half-height pocket with a bottom zipper closure. With the zipper opened, the bottom compartment can accommodate a telescoping handle for storage atop another travel bag.

Between these end caps, the CS5 provides 5" (width) of storage space that can accommodate a pair of headsets, a GPS unit, or similar items. It also includes a top pocket for sunglasses, as well as a Velcro-attachable divider shelf for perfect customizability. The CS2 provides 2" (width) or storage space that can house a laptop computer (up to 13"), a kneeboard, magazines, documents, and similar items. The CS11 provides an incredible 11" (width) of storage space that can hold anything and everything. It comes with two Velcro-attachable divider shelves and an 8" (square) top pocket. The four Side Pockets easily and securely attach on the sides of the CS11 and/or CS5 for quick & easy access to their contents. Outside dimensions measure 13.5" x 10.5" x 19". An incredibly well-designed storage bag that can grow - or shrink - as your needs change.
