MR.ICE Extra Large Gel Ice Packs for Injuries - Hot and Cold Gel Compress for Shoulder, Knee, Back and Neck - Flexible Ice Pack for Injury - 12.4" x 8.3" (Blue)

These come in real handy. Use almost every week. Will get more shortly. Durable, soft, reasonably priced. They do the work.

Stayed cold for hours between my back & back brace. Had L5-S1 fusion and this gel cold pac gave me great pain relief! Excellent buy.

Well made, great quality gel pack with clear instructions on heating/freezing, and safety. Perfect size.

Works great

I have back issues and was looking for a cold pack that stays frozen for awhile. No matter how long you freeze these for, they do not really freeze, just get cold and warm up quickly. Maybe 10 minutes of coolness....I'll take a bag of peas over these.
