Maybe you already have what you need, but are looking to enhance your gear. Check out the OSS Tac- Wrap Tourniquet, which is extremely easy to apply and designed for one-handed use. If you’re looking for a different type of rifle plate carrier, check out the OSS TAC II Plate Carrier.
It feels minimalist, but with 360 degree MOLLE compatibility, you can’t beat it. Holds 10” x 12” plates. Cummerbund opens to accept hard side armor plates or soft armor inserts, or internal rifle or pistol mag pouches.
