Neck straps are, well, a pain in the neck. A transmitter harness is far more comfortable to wear for extended periods of time. Here is one, that we really like.
The Revoc harness has a four-point adjustment system that allows your to tailor the harness to your body shape. The straps are a comfortable 40mm wide and terminate in hiking gear quality buckles. The back pad has a durable Nylon outer shell, a layer of padding and finally a layer of breathable nylon mesh. The harnesses single point connection strap is terminated with a metal hook that securely clips into the metal loop on your transmitter. In addition to the metal hook, the connection strap sports a quick release buckle that makes it easier to connect and disconnect the transmitter from the harness.
