    Great read. Would like to know how long the frio stays cool enough for insulin

    Hi Vicki,
    These units work by the evaporation of the water from the gel. When we place an alcohol wipe on our hand(s) it will feel cool as the alcohol evaporates. The website is very helpful. The speed that the gel returns to the solid crystals is dependent upon the temperature and the humidity. I have had the mid-sized units remain in a gel like state for over six days. Again, it is the temperature environment which you are located. As always have a great day.

    I’ve been using a Frio wallet for over ten years and I love love love it! If you soak it too long (overnight) the gel will swell to the point that you can’t get anything in the wallet. I usually soak foe a couple hours and that’ll last me a couple days. One important note is the wallet must be allowed to evaporate. I accidentally put it in a ziplock bag on a kayaking trip with my cell phone and since it couldn’t evaporate it got very hot in my pack that was exposed to sun all day. When we landed on the beach I had to skip lunch because my insulin was hot. The next day I let it free in my bag and it was fine again. Lesson learned!
