The F3F has a big barn-door front opening, a zip-around top opening which optimizes it for PRC-117 type radios, MOLLE/PALS compatible webbing up the sides, and two exterior front pockets. This is a great all-around 3-day pack, but we named it the FAC Track because it is the best-in-class pack for Forward Air Controllers.
Upper back wall radio rack with 3 antenna portals.
Padlock webbing tie-points all over the pack.
"Shooter's harness" with 3D mesh is vertically adjustable for varying torso lengths, and is both thinner for shooting, and more comfortable for heavier loads.
Numerous small pockets and organizers -- so you can always go right to what you're looking for.
Gossamer polycarbonate frame.
Handles on 3 sides make it easy to pick the pack up, especially when retrieving it from your vehicle.
Five hydration compatible pockets.
Includes G1RC Rain Cover, stowed in a zippered pocket in the bottom of the pack.
Ready to mount two AN2P or AA2FK pouches, or one A3SB Saddle Bag on each side (sold separately).
