When you get old(like me) things hurt. My knees, my shoulders, my ankles, my elbows. Everything is messed up. Moji makes great ice and heat wraps. The ice/heat packs are flexible and conform to your sad, injured limbs. And the wraps provide the right amount of compression. No more trying to balance a bag of peas or a ziploc bag filled with ice on my knee. They just came out with the Moji one, which works for quads, hamstrings, knees, calves, ankles, shins, shoulders, hips, and any other body part I imagine. I got it yesterday and it works great. And the packs can be frozen or heated in the microwave. The staff is really friendly and helpful when you call. Love this company.
