In very good condition (see photos).  Used a few times, wonderful stability and support, but compression irritated my skin.

From a smoke free home.

From manufacturer's website:

The new-and-improved GenuTrain provides secure support for mild instability and relieves knee pain and swelling.

With a new Omega+ pad, the support provides targeted stimulation to sensitive areas of the knee that influence pain perception and mobility. Its anatomically-contoured knitted fabric with soft textured surface provides gentle massage and activates the body’s proprioceptors to keeps the support in place. Embedded stays with flexible bending zones and donning and doffing aids ensure a secure fit and make the support easy to put on and take off. GenuTrain is soft, breathable and moisture-wicking, especially in the sensitive area in the back of the knee, for all-day wearing comfort.
