Frequently Asked Questions
How does the FlatPack Plus expansion system work?
The FlatPack Plus features a dedicated zippered expansion panel that, when unzipped, opens the pack's main compartment to approximately 150% of its compressed volume. This allows you to carry the pack nearly flat against your back or a plate carrier when lightly loaded, then quickly expand it to accommodate larger loads like extra clothing, hydration, or medical gear when the mission demands it.
Is the FlatPack Plus compatible with plate carriers or MOLLE systems?
Yes. The FlatPack Plus is designed with integration in mind and is compatible with most major plate carrier back panels and MOLLE/PALS webbing systems. It can be worn standalone with its shoulder straps or mounted directly to a plate carrier back panel, making it an excellent choice for both standalone day-pack use and modular tactical kit builds.
What is the difference between the FlatPack and the FlatPack Plus?
The FlatPack Plus is the larger, more feature-rich version of Haley Strategic's original FlatPack. The "Plus" designation indicates the addition of the zippered expansion system and increased overall storage capacity, bridging the gap between a minimalist assaulter pack and a full-sized day pack — giving you far more flexibility across different mission profiles and carry scenarios.
