Made with moisture-wicking Coolmax® fabric, Lomir's smart undershirt is seamless and includes a knitted rib pattern around the abdomen, for perfect fit and comfort. ECG electrodes are incorporated directly into the design, knitted into the shirt with the fine wires externalised at the back of the animal. Snaps are also installed at the pack, to fit directly onto the leads of the telemetry device.

Belt loops can secure respiration bands (RIP) and the entire undershirt can be paired with a jacket containing telemetry equipment in a pocket.
