Core Products Soft Comfort CorPak, No Frost Hot and Cold Therapy Pack - 10" x 13", Made in The USA- 2 Pack

This replaced one like it that I had purchased from my Chiropractor. It is a very good pack that is flexible and works for my back as well as neck. Very versatile and not too cold. Can be used without wrapping it first. Excellent Product.

the ice pack works great and will have NO frost on it if you fold it and place inside a gallon zip lock bag then put in your freezer. it folds well over knees, shoulders, back etc.

Great quality. Better than plastic gel ones for cold. Recommended. Keeps temps.

I like the softness of the casing. The therapy pack holds its shape well and lasts for quite awhile once it's taken out of the freezer for use. I haven't used it as a hot pack yet. It's easy to use and is slim enough to fin on the freezer door without being too bulky.

Bought these for my husband after surgery so he could rotate and always have one cold. I was originally concerned about it being clay and just wasn't sure that they would work well. They are awesome!! They stay cold for a very long time and mold completely around the area. The covering which is kind of like a fabric is soft on the skin and makes it all the more pliable. Couldn't be more pleased.

Great product! Great size.

Freezes well, I'm not sure exactly how long it takes though. Love that it doesn't frost. Heats in about 30-40 seconds, I personally like a somewhat hot heating pad but the corners did slightly burn my lower back when on direct contact with my skin after 40 seconds of microwaving. Loses heat after 15-20 minutes so if I want to use it for longer, I'll pop it in for 10 more seconds. I like the texture of the pad and it's nice that it's pretty flat so it stores well.

Very good product at holding heat. Works well with therapy. Haven’t used as a cold pack yet, but definitely approve of the heating aspect.
