MEDIUM TRANSPORT BACKPACK MOLLE SYSTEM COMPATIBLE This well made, Transport Backpack is made of 600 Denier tough polyester material. It has a waterproof bottom and PU coated lining and pockets for water repellency. We recommend using a waterproofing spray on it occassionally to retain it's water resistant characteristics. It is MOLLE compatible (Modular Lightweight Load-carrying Equipment). Any system that utilizes modular attachment methods and is usable with U.S. general issue MOLLE components is often considered "MOLLE-compatible" or is called a "MOLLE" system. Increasingly, non-military manufacturers are incorporating MOLLE technology into outdoor equipment. NOTE: This pack is not a US Government Issued item. It is an after market item made to be compatible with a MOLLE type system. The term MOLLE is used not only to describe the specific system manufactured by Speciality Defense Systems (the US Defense Contractor), but is used interchangeably to describe generically all load bearing systems and subsystems that utilize the woven PALS (Pouch Attatchment Ladder System) webbing for modular pouch attachment.With a Main Compartment of 17" X 8.25" X 4.25" and several other compartments, (see below), it has approx 1160 cu in. of space for all your gear.
