2 Granite Gear Air Cells Protection Insulation Cases

I had bought these many years ago. The purple case measures 9” length and height without anything in it is 3 1/2”, width approx. 5 1/2”. The orange case is 8”, 3” height and approx. 3 3/4” wide. On the website they are categorized as XS and S Cell Blocks. I bought them for padded protection, and insulation for electronics. Copied from the tags “Made with a new material called Temptrol laminated to 3/8" open cell foam. Temptrol is a polypropylene based non-woven perforated fabric that is metalized on one side. This new material reflects 95% of the radiant heat, the major source of heat transfer, to help anything stay warm or cold for much longer. It also offers protection from electromagnetic fields for sensitive electronics. Plus they have YKK water resistant zippers and an internal stretch mesh pocket. But, enough about the technology already! These things are just what the doctor ordered. They can be strapped on nearly any pack, they are built as light as possible.”
