Isolator Fitness 12 oz (4 Pack) ISOBRICK - Reusable, Long Lasting, Lunch Bag/Cooler Ice Packs

These are the best ice packs I've ever used. This my second set because my first set is a few years old and I lost one and another one was squished. I use these with a Isolator bag and together they keep my food cold all day. Even when I've used the ice packs in a small ice chest, they worked much better than the hard plastic blue ice packs. The only caveat is that these packs are soft and can be squished when not frozen if they are handled without care.

These are a great size ice pack. They worked great for me after surgery for 2 hip and 1 knee replacement. They stay cold practically through the night and can be used over and over.

They have been working great and staying cold for 10-12 hours

These are great for the Isolator lunch bag system and keep cold for extended periods of time. The only downside is they get lumpy and wear down quickly so I'm already on my second set in about a year. My husband uses the lunch bag a few times a week so this is not something that is overused by any means, they just wear out after little use.

These things are the best to pack in with your foods. They are smallish (depending on the size you bought) and flat. I’ve had mine for over 3 years and they are still going strong. They last a few hours (in my case how I use them 2-4 hours). They are not super long lasting but for lunches and short travels they work well.

These ice packs last all day And even in this heat wave for 90 degree days they are still cold at the end of the day. They fit great in any lunch box container. I meal prep an am on the road a lot - knowing I can leave my bag in the car with the ice pack leaves my mind at easy that my food is ok to eat!

I have used ISO products for the past 3 years and these are by far the best "ice packs" to use for lunch bags whether its a bag by ISO or not! I have recommended their products to many of my friends and they can say the same. My partner, brother-in-law and I use these packs for our meal prep duffle bags and our meals stay cold for up to 8 hours, INCREDIBLE!

I use these for my work trip when I am traveling usually for three days at a time. The packs will stay cold for usually around 1.5-2 days. If you end up having a small fridge in your hotels, they will refreeze in those small freezers or if you place them inside of the fridge touching the thing that makes the fridge cold, they will refreeze as well. I never have to worry about my food spoiling when I use these.

dachte erst die Kühlaccus passen nicht in die IsoBag, aber falsch gedacht hat alles gepasst!!Kann man also super gebrauchen

Ice bricks are much better than the original ice packs so very happy and they fit perfectly in the bag and don't get miss shaped in the freezer.

Item was described as "like new" condition but two out of the four bricks arrived with the inner "brick" broken. Item states not eligible for returns. Dissatisfied I was misled to purchase bad product.
