Carry: One of the key features of the Tradesmen Multi-Role Assault pack is that it’s meant to be directly connected to your armor. Directly connecting to the armor mitigates circulation loss from pack straps cutting into the armpits, stock weld problems, pistol presentation problems from reduced mobility, maritime release compromise and entanglement, excessive bulk of straps over the shoulder that occur with traditional shoulder straps.
GP Compartment: The GP Compartment is large enough to fit 1x 200 round saw drum and a waffle shirt (or similar volume item). There are 2 rows of internal elastic loops to organized your items for quick access at in low light/no light. In the upper left corner there is glove hook to secure sensitive items. Externally it has 9×3 MOLLE for attaching the optional Helmet Flap, Horizontal 5x40mm pouch or any other MOLLE compatible item. There are 2 grommet in the bottom of the compartment for drainage that have a secondary functionality when used in conjunction with the 2 drain holes in the main compartment can be used for a dynamic cinch strap for securing light loads to the bottom of the pack like wet weather gear, ponchos, patrol Ghillies or other similar items.
