Kodiak Polar Care Ice Cold Physical Therapy system, for sale at $50 only.

Circulates ice cold water to a waterproof pack that you can wrap around sore/swollen/painful areas after training or after surgery. Much better than using normal ice packs. *ice water not included ;)

Great for athletes recovering after training, or for post surgery reduction of swelling and pain relief.

I got this at ~$150 (already subsidized by insurance) when recovering from a shoulder bankart surgery (to fix right shoulder dislocation) and have no use for it anymore now that I've recovered.
