This is amazing
First off, the cold packs are top quality. The exterior was thick enough to resist puncture or tearing, yet pliable enough to form to your body. It never got too cold and didn't have any hard chunks inside like others I've tried. It also remained cold for a long time.<br /><br />At first glance I was suspicious of the harness. The part that holds the pack is thick cloth on one side and thin on the other. I was afraid the thin side would let too much cold get through and would be flimsy. Once I put the cold pack in it became apparent the fabric was stronger than it looked and offer my skin more protection than I anticipated.<br /><br />My only issue was the straps. While the velcro was remarkably strong, the elastic strap felt like it would loosen up over time. It was also very small. Without the 2nd strap you would need to be the same size as the model on the box to use the product as advertised. (Full Disclosure: I did not use the item immediately after unboxing. I'm not sure if the 2nd strap was missing or if I misplaced it. In either case, I can't say how it would change the experience. For that reason I only deducted one star due to the strap size. I'll look for the missing strap tonight and adjust my review accordingly if I find it.)<br /><br />TLDR: Great product. The straps may not work for bigger people, but the packs and their holder are well worth the price even if you have to hold it in place another way.<br /><br />UPDATE: Okay, found the second strap. All of my concerns are gone. It easy fit around my broad chest and held the cold pack firmly in place while I unpacked my apartment. (I just moved.) With both straps, the shorter one didn't have to work as hard and didn't feel as delicate. I've very  impressed.
