Icing use: works great w modifications
This is for use of it for ICING lower back pain: first of all the review who said the model wearing it wrong bse it's not to be used on the skin is wrong. The thick mesh is plenty protection for it not to burn your skin - use on skin if you want a "ice pack" it's still not cold enough for me UNLESS you put both ice badders that it comes w into the mesh pocket - doing that that =  more pressure on your back = colder. It has plenty of elastic stretch  to fit my 46" waist & then some. I like my ice packs very cold hence the word "Ice" Pack- it seems lots of reviewers are satisfied with a "cold" pack:  - wearing it walking around? -yes but it slips down so I used my generic back brace to hold it in place. Perfect! Do these modifications & you'll get the icepack you are looking for. This "put in freezer for 30 min then stays cold for 2 hrs" is ridiculous- they must be getting comped. I've several icepacks & all need to be in freezer for 2.5 hrs to  maintain a 30 min ice-like cold. I hope I answered some questions.
