The 2X5 Slotted PALS 4" wide Cordura cummerbund upgrade is made to work with the USMC Gen three plate carriers (Laser Cut) and others. We use eight inches of Berry Complaint Cordura which creates two four inch internal pouches. These pouches have loop sewn in place for our internal bungee kits or our large small Kydex insert that can be purchased separately. The cummerbund secures with a hook and loop platform and adjust from skinny to fat or in other words one size fits many. Two, two and half inch one inch bungee straps are sewn in place to allow for the perfect stretch. Quick release TakTic Buckles used to secure under your cummerbund flap for quick release. Will not work with side sapi plates.
