🧊 CHILLERZ Large Reusable Ice Pack (4 Pack) for Lunch Box – Long-Lasting Gel - Slim & Lightweight Cooler Packs - Keeps Food Fresh, Cold & Tasty Review

Working in an air conditioned home I found one of these backpacks kept the temperature relatively cool, but I doubt it would hold up for work and as well outdoors.

This is great! Keep my lunch and drinks cold at lunchtime and after. They're also nice and thin so they don't take up much space in my lunch bag. I love her! I plan to order more!

I'm very happy with this and will be ordering more. I've had them for over a month now and they work really well and the sleek design is one of the reasons I bought them. They keep everything in my fridge ice cold and sometimes freeze with ice, I only have to freeze them once a week.

Perfect size for personal mini fridge. So thin you can use all 4 at once to dress up cooler walls. Used with pre-chilled beverages, it usually lasts at least 8-10 hours in my little soft Yeti. Also great for use with ice. Ice lasts much longer.

They work well and I love how thin they are - I often wrap them (on 4 sides) around an item I try to keep my temperature bag cold on the way home from the grocery store. Much better than a single ice pack that only keeps a small part of the item cold while the rest stays not so cold. I have used them many, many times and so far they have held up well.
