By far the best cold pack on the market.strong, flexible, durable, and feels really great! I had been using refreezable ice packs that were hard and very uncomfortable. my physical therapist put this on me after treatment and I was amazed. it's really cold! I get such relief.this size is perfect for my shoulder and neck.

Just like the heavy weighted ice packs at physical therapy..

Was in a car accident in the beginning of the year this covers all of the effected area and works wonders on my stretched muscles.

Great big ice packs! Works great for my mom's neuropathy on her legs.

Love it!!! Very soft and flexible. It's a lot like the one they use at my physical therapy office.

Great product, very pleased.

Love them. I purchased because it's what my physical therapist uses in me after therapy. They cradle your leg.

I use this quite often! It is very durable - so much more than the same item in blue. The material on this black Colpac does holdup whereas the blue one does rip within 6 months to a year. Would like it to be longer in length but the quality is why I keep this one. Very important to lay it flat in the freezer! Thank you very much! Mary Anne

This ice pack far exceeded all of my expectations. my husband has severe muscle and joint pain resulting from multiple chronic health conditions. He cannot use heat to soothe the pain due to a blood disorder. So, he has to rely on ice packs for relief. We've spent a fortune trying to find an ice pack that will hold up, stay cold and not sweat too much. I even resorted to making homemade ice packs, using dish detergent and alcohol. They worked well for a while but would inevitably end up leaking. I finally stumbled upon these ColPaC brand ice packs after my husband had hip replacement surgery. I bought the large size, which has been perfect for covering his hip and upper thigh. I have also found it's nice to lay on to help with sciatica and back pain; because it cover such a large area. One of the best parts is that it does not sweat at all; so you can slide it in a pillowcase, place it on a sore body part and go to sleep without worrying about waking up in a puddle. I plan on going back and buying a smaller one; since I'm sure it will be more convenient sometimes. I just wished we had found this years ago because it has been a true blessing.

Much better than an ice bag!

This cold pac is exactly the same one used at my physical therapy clinic. It stays very flexible. It has a nice, strong plastic so it holds up well in a freezers w/ other items. The company states it stays cold for 30 minutes but I would say it was plenty cold for an hour. I wouldn't mind another one.

Best cold pack ever.

This ice pack stays cold longer then any I've used before. It's amazing.

Works great, just like the one at physical therapy.

I found out how much I needed this after I had it. Nice size and shape

works fine.. this is the second one I have bought for my wife... (still have the first one) the black polyurethane seems to hold up much better than the blue (is it vinyl? not sure) ones. I just wish someone made a nice cover for this... till then we just use a pillow case, keeps it from getting your skin too cold. shop around for best price

These are commercial level cold packs and have little in common with the cold packs you buy at your local pharmacy store.Great quality.

This cold pack has been getting a lot of use due to extensive knee surgery. By having 2 of them I can rotate them and have been able to keep swelling under control so much better than with just a machine.

Got this for my mom. Although it might be a bit heavy for her to carry around since it's big, she liked it so much I ordered another one.

Cold where you need it. Seems more durable than the model available at the pharmacy. Great item
