Bought these for a 4 day camping trip to a festival, as our usual iceblocks barely last a day. Used 4 medium packs in a 26litre Coleman coolbox, and they kept everything cold for the full 4 days. Even on the 3rd day, the orange juice was almost colder than what comes out of our fridge! The weather wasn't overly hot, but I was still very impressed with these, and recommended them to all our fellow campers

Super product keeps everything chilled for hours. These are suitable for a larger cooler or picnic bag as long as it is insulated. I have something smaller and similar in my lunch bag and it stay frozen for a good 8 hours. Nothing like a super cold can of drink on a hot Summer day! I’ve even managed to bring ice and ice cream to a picnic using these. Instructions to set up are easy to follow, definitely recommended.

Amazing product, easy to set up & keeps cold for 48 hrs, fits into the small freezer part of a fridge (great for when staying in self-catering) Great value product. Highly recommend.

Works great

Fits perfectly down the sides of the cool bag/boxes and on top encasing the food and drink keeping it cool for much longer than ice bags + without the problem of melt water.

Kept my beers cold for two days!

Very good at keeping food/drinks cold for a good length of time even in cool bag. Will be using them in cold box for travelling.

Product just has described, easy to fill good size.
