– Ice Packs for Coolers Reusable Long Lasting Freezer Packs for Lunch Bags/Boxes, Cooler Backpack, Camping, Beach, Picnics, Fishing and More

Freeze well, stay cold over a day. Handy to poke in the gaps where gel blocks won't fit. And good for standing upright so the cold is distributed top down. Best frozen flat so gel freezes evenly.

Very good. Maintains cold temperatures for hours.

Look the part but liquid in less than 24 hours

I exclusively pump breastmilk, which also needs to be done when I’m out the house. I bought these to put into an insulated bag, and then I could keep my milk at the right temperature when I’m out. These are big & last a long time which is perfect for what I need them for!

I freeze these, drop them in the water tank of my air cooler, it blows cold air, voila. Multipack is nice so I can cycle the ice packs once they've defrosted.

I'm used to having bulky heavy ice packs, I was looking for something to fit into my Tourit lunch bag without taking up too much space, Something that surprised me was how light and high quality these feel! I think they'll be perfect for the job!

Defrost way to fast useless in coolers,

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,

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.
