Frequently Asked Questions
How does the FlatPack Plus expansion system work?
The FlatPack Plus features a dedicated perimeter zipper that, when opened, expands the pack's main body to reveal up to 150% more usable storage volume. When compressed and zipped closed, the pack sits nearly flat against your back — making it ideal for situations where a low profile matters. The expansion system is smooth and intuitive, so you can adjust on the fly without removing the pack.
Can the FlatPack Plus be used as an everyday carry or commuter bag?
Absolutely. While the FlatPack Plus is built to military specifications, its clean design and adaptable sizing make it an excellent everyday carry bag, gym pack, or commuter backpack. The VELCRO loop panel can be left bare or dressed with patches to suit your preference, and the YKK zippers hold up to daily wear just as well as field use.
Is the FlatPack Plus compatible with hydration bladders or MOLLE systems?
The FlatPack Plus is designed with modular compatibility in mind. It features MIL-SPEC nylon webbing that supports MOLLE-compatible attachments, allowing you to expand your carry options with pouches and accessories. While a dedicated hydration sleeve is not confirmed on all configurations, the expandable main compartment can typically accommodate a standard hydration bladder — check with Goodland Guns for the most current specification details.
