REVIX Large Ice Pack Wrap for Hip, Knee, Shoulder, Back Pain Relief Reusable Gel Cold Pack for Injuries, Swelling, Bruises, Surgery, Inflammation 16x9''

These are the best ice packs! They stay cold for a really long time! The strap is not long enough to go around my (admittedly larger) waist, though, so it might be worth buying an extender strap with Velcro ends. They are big enough to treat your back.

Love this ice pack for my back and shoulders. Wish that the strap is a little bit longer to strap it across my back.

Justo lo que necesito, amplio y versatil. Para gente con 115cm de pecho necesitaran algo mas largo

I almost never leave reviews, but I am so impressed with the quality of this that I felt compelled to. I really wanted an ice pack that I didn't need to use a towel as a buffer between it and my skin, and this does that perfectly. One side is velvety soft and makes the ice a perfect temp for my skin. The elastic band is thick and supportive. Would highly recommend.

This product was a lifesaver while recovering from abdominal surgery. Good quality, sturdy but flexible strap with very secure Velcro. The felt side is very comfortable against bare skin, then you can flip it around to the other side to extend the cooling time. Pretty good ice retention. A solid half hour to 45 minutes of relief. Strap keeps the pack secure when lying down or while walking around.
