The Thor 40L patrol pack uses a modern design with a single main compartment storage area and additional storage locations on the lid panel, in the side pockets and on the back panel for an A4 folder. Pouches can be attached by using the MOLLE webbing on the sides, front and bottom. The interior can be very quickly accessed using the all round full length front zip.

Internal MOLLE webbing allows radios to be secured inside. Hydration bladders can be secured internally and multiple exit ports are provided for antennas, headset cables and hydration hoses.

The design facilitates adopting all firing positions and carrying out kinematic actions. KARRIMOR THOR PATROL PACK
