Campingaz Freez Pack M20 - Size Medium

With a good quality cooler box these will maintain a cool temperature for a couple of days if you are careful. They are easy to freeze and store and handy when you need to whip them out of the freezer for your trip. I find the various sizes are easy to spread the coolness around the box, easy to adjust. Only quibble is that one of mine developed a split on the corner. Does the job!

Got these for a two night camping trip as we couldn’t get electrical hook up and couldn’t use our electric coolbox. The weather was roasting but these packs kept our food & drinks chilled for the whole trip! My old freezer packs were defrosted by the time we reached our destination and these were still frozen solid! I was sensible & kept the coolbox in the boot of my car to ensure it lasted longer. Definitely worth the money - I’ve bought more of them now as they are so good.

They're OK they do the job, but both of them bulged rather spectacularly, the first time they went in the freezer. Surprising really, as there's plenty of room for the liquid to expand into.

Has handle built in making it easier to carry. Used for cooling water in carnivorous plant tray.

These work, we use them in our large cool box and they really work remember to freeze them in advance and pop into your cool box night before you fill!
