TOURIT Ice Packs for Coolers Reusable Long Lasting Freezer Packs for Lunch Bags/Boxes, Cooler Backpack, Camping, Beach, Picnics, Fishing and More (Set of 4, Blue)

Got a new cooler bag. I purchased these so I didn't have to use ice anymore. These are great. Stay cold. Always cold after an event. I let them defrost and leave them in my bag cooler to save on space in the freezer, because mine is packed, however they are small and easily fit in a packed freezer when you need them. I like that about them! Good buy!

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!

These are convenient for small coolers and lunch bags. They stay cold, but they don't appear to remain cold like the gel-filled packs do. These are filled with a liquid.

Defrost way to fast useless in coolers,

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!
