DREAMSOME Large Flexible Ice Pack for Back, 13"x22" Reusable Cold & Hot Compress for Knee Leg Neck Shoulde

The ice pack arrived quickly and I was a bit shocked at it when I saw such a small envelope it arrived in. It's a diy ice pack, it's paper thin when I took it out of the envelope, you will need to dunk it in water for about 5-10 minutes first, it soaks up the water and plumps it up, it's like a gell type material inside each spot, After I soaked it I put it into my freezer for 3 hours, it does freeze well. It does feel nice on my back for my aches and pain, the freeze lasted about 30 minutes before it needs to go back into the freezer. It's a very large size and completely covered my entire back, the enclosed 2 straps have very good Velcro attached to them. The straps were a bit hard to work. Overall I felt it's a good large size and did stay frozen for 30 minutes use.

It is a little thin, so it doesn't maintain cold temperature for a long time. On the other hand, the thinness makes it easy to wrap around arms or legs. The size of the pad is bigger than most others, which is good for covering large areas.
