Wosport tactical backpack WST 

A robust backpack that can be a great addition to Chest Rig type vests.
Thanks to a special design, it is possible to expand the capacity of the backpack. The rear zip, when opened, increases the capacity to approx. 15l. 
The main compartment, which can accommodate all essentials, also has a separate compartment for hydration cartridge, while the rear pocket is perfect for transporting small items such as documents, wallet, charger, map, etc.
The backpack's shoulders have loops, which will be useful for organising cables or the hydration cartridge tube.

On the inside of the backpack there is a row of Molle webbing, which, together with shoulder buckles, will allow connection of the backpack to tactical vests.
The backpack's shoulders have also been equipped with a chest strap, which will improve the stability of movement with the backpack
