TOURIT Ice Packs for Coolers Reusable Long Lasting Freezer Packs for Lunch Bags/Boxes, Cooler Backpack

Very compact and stays cold even when it becomes fluid

I must first mention it’s built pretty solid and can see having this for long term use, the only downside is that it melts rather quickly, lasting probably less than four hours. By two hours more than half was already liquid, and the drinks were already cold when I put them in. It did keep my drinks ice cold until I got my cooler to the fridge though so that was certainly a win however I’ve had ice packs last for six hours and still be 80% frozen. Those are far too large though and cost $20 each. For my needs it works perfectly. I don’t have enough room in my cooler for the 4x6 ice packs. In the picture shown I actually still fit another 19oz tallboy. These help fit an already crammed drink bag. Black bottle: 28oz, Blender bottle: 42oz, 16 oz monster,

So great! Use these to keep breast milk cool in my diaper bag. We were at the Miami zoo in August and my bottles stayed cool all day. Super easy to use. Slim fit doesn’t take up lots of diaper bag space. I’ve flown with them frozen many times and never had an issue getting through security. None have broken or busted and I use them OFTEN! Definitely recommend buying

These work well, HOWEVER if you use less than 4 in a lunch box, cooler ect they will melt quickly. If you have more than 5 they stay cold much longer.

These are super thin and fit perfectly in my lunch box. They keep my food cold for my 1.5hr train commute into the office. I don't think they'd last all day but I don't need them too.

these are pretty cool for back pack coolers and seem to have held up nicely

Not sure about some of the reviews! I bought these for the versatility, and due to the 5 star review about staying cold for 12 hours. My husband works 12 hour shifts, so I thought these would be great! Not so much. .... first he has an isolated zip bag that he keeps his water and lunch in which he stores in an air conditioned portal. He used all 6 ice packs and by the time eat ate lunch 7 hours into his shift the water was cool, but not cold and his food (if not being a sandwhich) would had been thrown out as it was below the "cool" threshold. Maybe we got a bad batch?? I don't know. I can say they seem extremely durable and do not leak!

Great
