Core Products ACC-551 Soft Comfort Corpak Hot & Cold Therapy Pack, Large

This is an extremely high-quality ice pack. They are very generous with the amount of gel filling, so there is a lot of thermal mass allowing you to ice joints for extended periods without it getting warm. One of the things I like most is the pliability of the ice pack even when it is straight out of the freezer. It remains very soft at all temperatures, so it is easy to bend and shift the filling material around when needed. Finally, it is absolutely perfect for knees, as the tri-fold design allows it to wrap around and make contact with the entire lateral, medial, and anterior parts of the knee even while you are sitting with the knee bent at a 90-degree angle. I highly recommend this product.

These are the best cold packs. Stay cold for a long time and mold to your limb while cold. I have had this two pack for three years and they are still like new.

I ordered these for icing after my knee replacement and they worked well. Easily moldable and hold the cold for a good while. They r thick and have some weight but it was ok.

These work exactly as advertised. I purchased my first one of these in 2011, and it still has nor tears, leaks or other problems. They say it doesn't 'sweat' or frost up, and that is true. They are very flexible right out of the freezer, and stay cold a long time. Made in USA is a plus for me, also.

This is my 3rd purchase of this product. I keep several on hand as I need them for my knees and arm. The product is so flexible and when I use it as a cold pack it revives mobility which I much need!!!! Wonderful product!!!
