Natick – the home of the researchers who created the things you love most, like woobies, OCPs, and the chili mac MRE – came up with another creation designed to make your life in the desert a little easier. It just so happens it would make your life on the beach a lot better too: the combat cooler.
The reason for the creation of the combat cooler was not just a way for troops to have rockin' sand and sun parties in the middle of the desert. There was actually a mission-necessary function for it. The Joint Program Office for Mine-Resistant, Ambush-Protected vehicles needed a way to protect soldiers when hit by IEDs or other explosives during an ambush. It seems the bottles they carried (along with the containers for other beverages) can become dangerous projectiles in such an explosion.
So the Pentagon asked the U.S. Army Natick Soldier Research, Development and Engineering Center if they could develop a way to mitigate that threat while making the water easy to reach and cold enough that soldiers would want to drink it. The result was the Insulated Container for Bottled Water, or ICB.
Natick's idea also had to include a way to keep MREs from becoming the same deadly projectiles. So along with insulation to keep the inside cold, they used a zipper system to keep the bottles in at one level. But knowing that zippers will fail, they also used a webbing system to encase the bag, which also reinforces the opening, which is done through a zipper. Now your combat cooler can carry/withstand 6,000 pounds.
And even when your zipper fails, there is still a way to close the cooler.
The largest tacticooler (my title, not theirs) can carry up to 36 bottles of water or 28 MREs, that will withstand drops, fire, vibrations, and even the harshest climates. So even operating in a 120-degree combat environment, soldiers could still count on a nice cool drink when they get back to the MRAP.
