Mueller reusable cold/hot therapy wrap is ideal for the application of cold or hot therapy to large body parts or limbs. Adjustable ends and the pack pocket are in an “H” shape while the velcro detachable extension strap can help secure the therapy wrap in place. The large wrap holds one 15cm x 23cm reusable cold/hot pack. Ideal for larger body parts like the knee, shoulder back or thigh. The pouch size is slightly bigger than the Reusable Gel Pack, 15 x 23cm and has a velcro tab at the top securing it in place, while the size of the neoprene wrap is 23 inches or 59cm from end to end and the velcro fastenings on either tip can adhere to anywhere on the whole wrap. The elasticated extension strap is 29 inches or 74cm long, unstretched, and has the hook velcro on either end facing the same direction. The gel pack should never be applied directly to skin, when cold or warm, and the temperature should always be checked carefully before handling. Please follow the instructions with the pack.
