Cooler Shock comes in Large, Medium, and  Small (lunch size). The large is 10″ by 14″ by 1.5″ thick. The medium size 10″ by 10″ by 1″ thick and is half the cooling capacity of the large size. The small lunch pack is 7.5″ by 6.5″ by 1″ thick and is just shy of 1/4 the cooling capacity of the large.

DIY packs come in the original zipper closure which requires that you add water then seal with a clothes iron. Available in large and medium only.

Our most popular version is the screw cap seal.  You simply add water, put in the silicone plug provided, then screw the tamper evident cap on. Available in large, medium and small. By far the easiest pack to fill.

Many customers love the original packs but did not like the ironing part. As a result, we created an alternative solution called the Slide Lock. You simply fill  it, zip it closed and then slide on a stiff white plastic zipper lock across the top. It then doubles as a handle.
