how long will ice pack stay frozen?

Several hours - I don't know exactly, but I know we've had food and drinks in there for at least 5 hours and everything was still cold.

I did not use ice packs. I froze bottles of water. I would leave around seven in the morning and the water was still mostly frozen at three and four in the afternoon. I do not know how long an ice pack would last but it would be at least as long as in any other bag of this type. I would recommend this bag to anyone. It is a good quality cooler.

Personal opinion: no. You need frozen ice packs to retain cold for any length of time. You could bring ziplock bags and put in fresh hotel ice each day and night. Just double bag the ice to prevent too much condensation. I always ziplock bag my meds too to prevent water damage. Have a good trip.

I agree with Hana - if the bus is regulated temperature, the items will no longer be frozen after 7-8 hours. At about 3 hours, frozen items begin to get soft (I transport frozen or cold food in this bag every weekend on a 3 hour drive.) You might look into using dry ice for packing.

Yes! I am amazed at how long this will keep ice frozen. I have left it in the car when out running errands and it stays cold several hours. In the house it will keep ice greater than 12 hours, but it does melt a little faster when in hot environments.

It will not. Ice will last for hours not days in here as the unit itself is not a "freezer".

Only one person on here is right, these packs stay cold forever without refreezing them. Anyone who keeps them in the freezer is just wasting energy. They use nano-size perpetual motion devices as minature a/c units and vent through osmosis.

I would leave medicine in this after the pack being frozen for at least 5 to 7 hours traveling on a plane, the medicine would still be cold.

It stays longer than 15 minutes. If you keep it in the freezer over night, it will stay frozen all day.

Don't know about an ice pack but will hold ice about 5 hours. Pretty good cooler

It stays pretty cold. If you are worried at all, I would put in one or two small ice packs just for extra chilling.

Hi. I have never tried to keep the ice pack in the cooler bag for more than 7 hrs. So im really not sure how to answer your question. I really doubt though, that the ice can last that long

As long as the ice pack is in there, the milk stays freezing cold. I used to take it to work for 15+ hour days and my milk would be freezing when I got home.

I suppose if you have something frozen that you put in the pack, it might keep everything else you have in there cold. We used this to travel in Eastern Washington, temps were in the 90's and we used a small amount of ice from the hotel and it didn't melt. Hope this helps.

It depends on the medication you are travelling with. We use it for growth hormones which needs to be kept cool. I would recommend taking ziplock bags and fill them with ice regularly. The case has a compartment for the ice pack and I do not think it would stay cool very long unless it is frozen. If I were travelling, I would use ice, then refill whenever I stop for gas. With an ice pack it will stay cool for up to 6 hours. I love this thing. Happy travels.

These are re-freezable ice packs, not the one-time use chemical ice packs. Just pop it in the freezer for a few hours and it will be hard as a rock and ice cold for a few hours use.

Only a few days. I know some people that had good luck freezing it in Ice cube trays so it would last longer.
