The versatile design of the Swede-O Joint Wrap comfortably surrounds painful, inflamed joints with cold therapy. Use the adjustable straps to provide compression and secure the pack to the painful area to help provide long lasting, drug free relief. The plush fabric is soft to the touch and gentle on the skin and slowly releases cold therapy for subacute injuries while the smooth surface quickly releases cold therapy for acute injuries. The nontoxic, biodegradable fill in this pack stays soft and pliable when frozen. Simply store the pack in the freezer for a minimum of 1 hour prior to use; the pack will remain cold for 20-30 minutes. Reusable.
