TOURIT Reusable Ice Packs for Coolers Long Lasting Cooler Ice Packs for Cooler Bag, Lunch Bags/Box, Cooler Backpacks, Knee Injuries, Back Pain Relief

Really pleased with these ice packs. I like the fact they're relatively thin, but they keep frozen and then cold for much longer than traditional ice packs of a similar size. Easy to add the water and 'set up'. Haven't experienced any leakage with mine. Obviously there is some condensation as they melt, but probably less than a traditional ice pack. Do check the sizes. I had wondered if I'd want some the next size up, but they're actually huge and wouldn't have fitted in my cool bag! These are perfect for my needs.

Works well, they certainly last longer than standard packs and are relatively small, leaving more space for drinks and food. They still work well after having them for a year.

Best ice packs I’ve bought. They stay frozen in my yeti cooler bag for 2 days.

Highly recommend - Keeps frozen for a long time, I use these a lot while travelling. To help keep things frozen or cold on a long camping trip, I would recommend a bed of ice at the bottom of the cool box then a layer of these then another layer of ice, and these blocks will keep the ice, for days!! Once defrosted re freeze and use again!!

After 8 hours still frozen solid. Bulking out in the middle, the result outweighs that small fault.

Easy to use and work really well. More then 8 hours in cooler bag
