FRIO COOLING PRODUCTS The FRIO wallet is an innovative product that solves, in an effective and economical way, the problem of keeping insulin at a safe temperative without refrigeration. They are light and compact, activated by water only, keep insulin cool for up to 48 hours, are reusable, and NEVER needs refrigeration. The principle is simple. To activate the wallet, it is immersed in cold water for 10-15 minutes. Crystals contained in the panels of the wallet expand into a gel, which remains cool for several days -- relying on the process of evaporation for cooling. When in continuous use, succeeding immersion times will be shorter as the crystals are already in gel form. Although activated by water, a feature of the product is that, after towel-drying, the FRIO wallet is DRY TO THE TOUCH. The FRIO wallet is formed by two compartments. The INTERIOR part (65-35 Poly-cotton) has panels containing super absorbent crystals, which are non-toxic and non-flammable. The OUTER pouch (Nylon Polyamide) is manufactured from a DuPont "Cambrelle". This pouch is permeable and facilitates the evaporation process, as well as the stability of the temperature inside the wallet. I, personally, am a diabetic Registered Nurse with an insulin pump and I travel extensively. This past two years I went to Alaska, Canada, Mexico, Caribbean, Tahiti, and Africa, as well as on a medical mission to the Guatemala highlands -- with no ice in sight for two weeks. The FRIO products have given me a freedom that I never had before. No more need to worry about ice chests, ice packs, cold freezer packs, hotel refrigeration or ice buckets (indeed, on one trip my insulin was thrown away by cleaning staff who did not see it sitting in the hotel ice bucket). The wallets fit easily into my purse, briefcase, lunch sack, backpack, airline carry-on, and some pockets. Diabetics have enough difficulty being away from the comforts of home, but keeping your insulin at a safe temperature now doesn't have to be part of that stress. The other non-diabetic products also enhance life's enjoyments. The NEW drink coolers are amazing -- they keep soda or beer cans, water bottles, ice tea bottles, etc cold for HOURS, instead of minutes like the other holders. The head, wrist, and anklebands are cool and refreshing in hot weather (whether relaxing or exercising) and make great gift ideas.

KEEP IT COOL, SO YOU DON'T HAVE TO BE.
