" One of the main issues faced by a diabetic at extreme elevations is the temperature ranges encountered, and the potential for insulin to denature if it gets too hot or too cold. In the past, we have tried combinations of creative packing, placement, and a little luck to let the insulin survive. In summary, my experience with Frio Cooling products has been exceptional. The product itself delivers on its promises, and will become a standard piece of equipment in my gear bag. In fact, I have begun using it in less extreme environments (I plan to use it this summer). I would personally recommend the Frio cooling wallets to any diabetic who needs to take their insulin with them." Extract from IDEA 2000 Review of Frio Cooling Wallet Performance during the Expedition to Cerro Aconcagua Todd Clare, President, IDEA 2000 "I had to write to tell you just how delighted I was with my Frio cool packs". I have just returned from a fly-drive holiday in California and Arizona and had no trouble with my insulin. Thanks to your fantastic product I was able to visit places such as Death Valley (120°F) and the Joshua Tree National Park (90°+). Thanks!!" Mrs J Birch, Sussex, UK "The bags were essential for me to keep my insulin cool during the lowland trek when temperatures were very high. I also found that they provided sufficient insulation to prevent insulin from freezing at high altitude [during the Everest Marathon]." Dawn Kenwright, First Lady, Everest Marathon '99 "I wish to inform you that I used two extra large FRIO packs during a five month trip to Australia, Indonesia, Hong Kong, Thailand and India. I did have doubts that...insulin would survive this time span in the heat. I need not have worried." Ms. A. Thorne, Lancs., UK "...in Tunisia our room had neither 'fridge' nor air conditioning, so we were relying on the FRIO wallet...but it was to endure an even stronger test, a 2 day safari in the Sahara! With temperatures up to 150°F the wallet more than proved itself." Mr. G. Rees, Birmingham, UK "We went to an outside show for 3 days. The temperature was 90°F plus all weekend. The insulin was still cool when we arrived home after a 4 hour drive. If anyone has any questions, I'll be happy to lend a hand." Carolyn Dennis, North Carolina, USA "I used a FRIO pack in Pakistan for a month at temperatures of 45°C and quickly realised that I no longer needed to worry that my insulin would be ruined by hot weather." David Thomasson, Film Director, Tyne Tees Television "I was so delighted with the results of your products. I would just like to thank you and congratulate you on the effectiveness of your packs. We travelled around 3,000 miles including parts of the Arizona Desert, Grand Canyon, etc. and I had no problems at all." Ms. M., N. Ireland "After I heard my 'sentence' - diabetes mellitus - I was determined about one thing: I would not stay at home pining. So I had to travel with a heavy thermos flask containing some ice and my insulin. It did work, but it was not easy and certainly not discrete. Neither was ice to be found in all places, nor did the flask prove indestructible. But I was not complaining! Then I discovered FRIO. What a miracle! Now my insulin is only a small package in my hand luggage. Together we have travelled many miles in Asia - as tourists through the Sunda Islands and Sulawesi, for a TV documentary to the Philippines, for my book "Atjeh,Atjeh!" to Sumatra and last summer to a hot China. Conditions were often primitive, but there was always a washbasin or a bucket from which my FRIO wallet could absorb some water to keep my insulin at a safe temperature for days. What a travel companion! In order to preserve our friendship for posterity we had a picture taken at one of the world's wonders: the Great Wall of China. Although the temperature was 32° C, as always this did not effect my insulin." Jelte Rep, producer & author, Holland
