Caldera Instant Cold Pack (Twin Pack)

one of them somehow got activated. Its possible that maybe cold activates them? As I had it in the side pocket of a cooler that I take to my son's little league games. I brought the cooler home and removed the pack and it had been activated. No body touched the packet though.

Shipped quickly and safely. When you have a soccer team to coach, these come in handy. No refrigeration needed prior or at time of use. Just activate and you're good to go. What a bruise saver! Hope they don't run out of these! Some brands don't get as cold or last as long....This is a good one.

They look like regular cold packs to me. I assume they'll work when needed.

Have not opened one up yet as I have had no need.Great to have in case of emergency or disasters.But I have had neither.

One pack worked very well unfortunately the other was a dud. I guess during shipping it got activated? Not sure if I’ll order these again.

they work great my first aid kit rocks, i just need to get a few more thing and it will be the ultimate kit

Great product to have on hand for back up. Works great! Would buy again!

did not last long...3 innings of a baseball game and it got warm

Gets cold in a flash. We bring these to baseball practice and they get used up by anyone who gets an injury. Doesn't stay cold for too long, but does the job on the spot. Good for a quick cool-down in hot summer too.

Good packaging, and these ones get much colder than other brands, like an actualice pack from a freezer (of course the packing isn't cold like a freezer pack would be). It's too bad they don't stay cold for more than 10 minutes, but I find that taping a piece of aluminum foil on the side contacting the skin helps the heat to dissipate faster. Overall good product

Good product but... be sure to read the description: these are "one time use"/ non-reusable cold packs. If you are looking for reusable gel-type cold packs, look elsewhere.

Great product to have in the first aid kit.. however one arrived already activated and was no good.

Shaked for 30 min no activation and sign of getting cold
