With the OP/TECH USA "Connection System", you have several options of connectors. This enables you to buy an extra set of connectors to customize the strap to better suit your needs. Straps can be lengthened to be worn across the chest or shortened to be worn at chest level. Another feature of the "ConnectionSystem" is the small carrying handle created when the quick disconnects of the "Connection System" are latched together. Available in sets of two and only from OP/TECH USA.
