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.
I need to be able to carry multiple things and in variety of situations. This bag has the flexibility to meet any needs and can be made smaller based on need. The use of space is exceptional. This bag was recommended to me by a friend, who said this was going to be his next buy when his wears out. This bag is well worth the cost.
Excellent bag. Adjustable compartments are definitely a plus for organizing flight materials as well as test flight equipment.
