The problem with a bulky item on a velcro panel is that most pockets are shallow — a jump pack, a folded rag, a pair of gloves or a compact first aid kit will not sit in a 1 in slot. The Modular Velcro Mini Cargo Pocket is 7 in wide, 7 in tall and 5 in deep, which makes it the deep box of the Modular Velcro line: it takes bulk, and it holds that bulk against a vertical panel without sagging off it. This is part of the Modular Velcro system. The back is covered in hook velcro strips, and the pocket presses onto any loop-velcro surface — the Modular Velcro Seat Organizer panel it was designed around, the carpeted ceiling or wall of an off-grid trailer or camper, a van build, or a loop panel on a pack. Velcro, not MOLLE, is the right mount here because you rearrange the panel: you can pull the pocket off, move it 4 in left and put it back in one motion, with no straps to unweave. Depth is the choosing point across the line — the 3 x 5 in Pocket is for a phone, the Medium Box Pocket is 2.5 in deep, and this one is 5 in deep for the things that will not lie flat. Dimensions 7 in wide x 7 in tall x 5 in deep Material 1000D Cordura Mounting Hook velcro backing; attaches to any loop-velcro panel Included Pocket with velcro hook strips Colors 17 options Origin Hand-sewn in North Salt Lake, Utah Warranty Lifetime workmanship What to know before you buy Velcro backing needs a loop-velcro surface to grip. It will not attach to a bare seat back, to smooth vinyl, or to MOLLE webbing. And because it is the deep pocket in the line, load it with sense: 5 in of depth times a heavy item is a lot of leverage on a velcro joint.
