Insulated Easy Zip Lock Resealable Aluminum Sandwich Bag - Reusable Thermal Lunch Snack Bento Picnic Hot & Cold Pouch (3, Small - 6 x 10 Inch)

Great price and does a great job!! I mailed frozen food across the country from west coast to east coast. The post office delayed my shipment by 2 days even though I paid over night shipping. A total of around 3 days till it go to its destination and I was worry it would go bad, but these coolers did the job!! Kept everything frozen! Recommend if mailing frozen food: freeze food soiled, put in these bags with tons of gel packs, and good to go! Haven’t tried it with warm food but I’m sure it will do great.

When traveling you dont want to lug around bulky insulation bags to keep food and drinks cold (or hot) when you're on a tour or hiking. These insulator bags were perfect. You can fold them to fit in a pocket in your suitcase or backpack, they are large enough to hold quite a bit, and the seal across the top is tight. The top handle is strong enough not to rip through.I'm going to buy another package just to keep around as needed.

These bags would be better if reinforced at the edges. I reinforced them myself with packing tape because all of them started to split before using them. Easy to put a strip of packing tape on all edges to prevent this.

These bags are useless! If been better off wrapping my burritos in a towel.Even double baggs them.Not even warm after 3 hrs.

They rio or tear when you are opening the seal and they don’t keep your food warm.

Filled it with ice and it leaked everywhere.
