It's still good but I thought your entire arm was goi g to slip through instead off the sleeve being held on your arm by Velcro straps. The strap that goes around your chest is a little irritating under your armpit if you are wearing a sleeveless top.
That being said, it does make my arm feel so much better than any other ice pack I've tried. The sleeve keeps the ice in place and really helps with the pain. I have frozen shoulder and it is one of the most painful things I've ever experienced. I would still recommend this product.
