Rev. Lang is Legendary For Making Your Regular Ice Last For Hours
In 2007 Rev. Lang was formed to bring the science of cool to outdoor enthusiasts nationwide. We set out to build a superior ice replacement system that would replace cooling bags and physical ice, making it easier for customers to keep their items cold. Although our products were originally aimed at outdoor enthusiasts such as hunters, campers, and anglers, we realized our products had far-reaching appeal, including anyone who wanted their coolers to run at peak efficiency. From avid outdoor enthusiasts to fans who want to make sure their drinks stay cold and frozen, Rev. Lang will get the job done.
Rev.Lang uses high-performance "phase change material", commonly known as PCM, and each model has a solid HDPE plastic shell design that provides excellent cold insulation.
Rev. Lang Ice Pack vs. Other Ice packs
Rev. Lang's proprietary cooling gel mixture is denser than ice and uses a scientific phase change formulation, providing a higher energy concentration for sustained cooling at 18 degrees F to keep your food and drink cold longer.
Key Features

These were small enough to fit in all of my lunch boxes, but large enough to keep things cold. I work in EMS and work 48 hour shifts. Sometimes I forget my lunch box in my vehicle which in the summer can get well over 100 degrees. This last 48 hour shift I left it in my vehicle for more than 8 hours and when I ran out to get it, it was still cold! all of the drinks and frozen meals were perfectly cold. Impressive. I would recommend these to anyone looking for something to add to their daily lunch box to keep things cold.

These keep cold, and fit in the lunchboxes for the kids. A good value and solve a problem. Have purchased more than once.

I have used "ice blocks" like this for years, but this is a first time having these small units. The compact size fits easily in the freezer as well as into smaller lunch boxes and packs. I put 3 in my lunch box: one on each size and another on top, which keeps things chilled for many hours inside a reasonably insulated bag. They seem plenty durable and easy to wash in the sink if food spills require it. Although it may seem like a lot to pay, it's a durable convenience item that will last for years.

This is an essential picnic item. So easy to use and convenient to place in an esky or lunchbox. The flat design is much better than the larger bricks that are available, since it does not take up valuable food storage space.

I was looking for slim icepacks for my boys lunchbox. These are great as they are very slim and I can fit two side by side in the boys lunch box and they don't take up much room. Would happily buy again.
