Wosport WST Flat Pack Backpack — MC Black

The WST Flat Pack is a compact tactical backpack in MC Black, designed for those who need lightweight, modular carry that attaches to existing gear or works as a standalone pack. Its core feature is an expandable wedge system that takes it from a nearly flat profile up to 9.6 litres of usable volume, adapting to whatever load you're carrying without swapping packs.

The main compartment fits a 1-litre hydration bladder and can hold electronics, documents or a tablet up to roughly 20×30 cm; the secondary admin pocket is sized for batteries, chem lights, energy gels and other frequently accessed consumables. The separation between the two compartments is functional, not cosmetic: it keeps emergency kit apart from the rest of the load so you're not emptying the pack to find a small item.

The external attachment system with PALs/MOLLE straps lets you mount the Flat Pack directly on a plate carrier, assault vest or chest rig, making it an extension of your ballistic carriage rather than an extra bag on your back. The integrated chest strap provides additional stability when the load increases or the terrain demands it. Worth noting: the compact profile gives good freedom of movement but offers less weight distribution than a pack with a structured back panel — this is a complement to a load-bearing system, not a standalone solution for extended carry.

Key features

• Dedicated sleeve for a 1-litre hydration bladder: integrated hydration without eating into storage space.
• Back panel with PALs/MOLLE straps: mounts to plate carriers and assault vests, eliminating the gap between pack and body.
