The most important point to remember when deciding on the best plate carrier for a big guy is that the ballistic rifle plate is designed to protect your heart and lungs. With this in mind you still may want a vest and rifle plates that provide more coverage especially if you are a big guy. At 6'5" 300 pounds, a former US Navy EOD Tech and owner of EOD Gear I feel uniquely qualified to answer the Warrior Assault Systems Quad Release Plate Carrier is the best option.
It's the best plate carrier for big guys and for normal guys that want even more ballistic protection because it is made by Warrior Assault Systems. This plate carrier will hold up and is proven in combat. It is lightweight, is hydrophobic so it won't hold water and sweat, has a low IR Signature so it won't glow in the dark when seen with night vision and is just built to last.
It is designed to hold 11x14 body armor plates front and rear. The front pocket does accommodate a 10x12 rifle plate but if you go big then get the 11x14 front and back.
Most plate carriers hold 10x12 rifle plates but it you are looking for the best plate carrier for big and tall bodies, then the Warrior Assault Quad Release Plate Carrier is your best choice. Like all Warrior Assault gear, it is very well designed, manufactured, is lightweight, will not absorb water and sweat and has a low Infrared signature when viewed through NVG's. Your entry level plate carriers will glow when viewed using Nods.
The Warrior Assault Systems Quad fully wraps around your torso and accepts soft body armor should you go that route and is designed to hold 11x14 rifle plates. You are able to use a 10x12 rifle plate up front. If you are big and tall then run with the 11x14 body armor plates. We can also create a custom plate carrier setup for you using lightweight rifle plates and backface energy reactive trauma pads.
Available in Coyote, Multicam, Black and Ranger Green, the Quad is the best quality option for big and tall guys. I personally am 6'5" tall, 300 pounds, am a former US Navy EOD Tech and owner of EOD Gear. If you are in the Nashville area and are big and tall, please come by EOD Gear.
