I really like this set of ice packs. It comes with a comfortable sleeve to put the get pack in after you cool or heat it. There is also a velcro strap to hold it in place which is nice so you don't have to hold it there yourself. The gel packs stay flexible after you put them in the freezer so they will form to where ever you place them. I like also that you can use them for either hot or cold therapy . This is a great set. I received this item at a discount for my honest review.
