Koolpak Original Instant Ice Packs - 12x29cm Cold Therapy Packs for Injuries & Pain Relief - Quick Squeeze Activation, Single Use - Stays Cold for Up to 40 Minutes - First Aid Essential (20 Pack)

These are great to keep in the car. You never know when a dog walk can result in an injury, to human or dog. Or even to help cool down.

I’ve taken up running, but have to look after my ageing knees. I like to ice my knees after a long run and, for a run that ends back at home, a small bag of frozen peas kept in the freezer can’t be beaten - and can be reused many many times. These cool packs are not quite as effective (not as cold) as a bag of frozen peas, and can’t be reused (or even eaten), but for a run that terminates anywhere other than home, they are pretty darned good.

Instant cold ice packs relieves pain quickly all over the body. Don't apply directly to skin wrap in a thin T towel

They get cold instantly and the temperature is really impressive. Unfortunately, the cold only last a few minutes. Not worth it at all.In vest in freezer bags and fill it with ice.

I am very pleased with this product. Easy to use, instead of ice bags/packs that go in the freezer, you simply twist to activate. The coldness lasts several hours.

Following total knee replacement I used these for when I was travelling or at work and didn't have access to a freezer for the full knee ice pack. They work well for swelling and are easy to use

arrived well, as far as kool paks go they are good. as strange as it sounds I'm hoping I never have to use them.

I did not realise that these frreeze packs were throw away after one use .Also having arthritis I find it difficult to get them hem to work .
