The ice packs will help to keep your food fresh and drinks icy cold. Deep freeze them in the freezer before using and put them in your plastic cooler or insulated bag. With its unique shape, the PINNACLE ice pack freezes fast, allowing less time in the freezer. The ice packs are reusable, durable, and reliable, so once you buy them, you will use them for a very long time, thus saving money on food and cold beverages when going on outdoor recreation. The ice packs are much better than the ice because they will not leave a pool of water; all you need is just to wash them after use. It is a necessary and useful thing for outdoor lovers!
