General Medi Instant Ice Cold Pack (4”x 5.5”) – 8 Packs Disposable Cold Therapy Ice Packs for Pain Relief, Swelling, Inflammation, Sprains, Toothache – for Athletes & Outdoor Activities

Needed to use a few at nights during a 7-day hiking trip where the I fell numerous times and had lower back soreness from carrying a 40lb pack all day. They not only got cold quickly, but they were STILL COLD THE NEXT MORNING. They're small, but for emergency use and when you need to pack multiple packs without weighing too much or taking up too much space, they're perfect.

It’s good for on the go and easy to use. Loses cold fast but it’s for a quick response to a fall or a bump to have in your bag. Very well made and comfortable to use. I refreeze them and use them as ice packs for my small cooler so I extend it to another use.

I have endometriosis and migraines I use I've packs daily in abdomen and head but I needed something I could use while travelling abroad etc These are now part of my tool box and for the price it's a win They stay cold for a good enough time 10 solid mins 15solid mins I'd say Shake - Fold - Shake

Instant coldness when squeezed, however doesn’t stay cold for 10-15 minutes as stated. I would say more like 5 minutes if that.

Well, these ice packs are designed for one time use but my daughter and I use them repeatedly for different issues that we have going on. They refreeze well. Good purchase for the price. Very small but work well for us.
