FRIOLarge Cooling Wallet - Insulin Cooler for 45+ Hours of Stress Free On The Go Cooler Bag - No Ice, No Stress

My son has some serious food allergies and I searched high and low for the ideal solution to keep his epipens at a safe temperature for a recent trip to Disney. These were the perfect solution, even when the temps outside were over 90 degrees!I did a few tests using terrarium thermometers with probes, and compared these against refrigerated cool packs in an insulated case. The cool packs turned hot after 3 hours in our best insulated case. These, however, kept the epi pens under 77 F even when it was 92 degrees with 70° humidity and we were out for 10 hours (though some of those 10 hours were indoors and on rides in air conditioned spaces).Each morning, I soaked the insert in the hotel ice bucket with a handful of ice and cold water from the sink and then towel dried off and let it sit for 5 min. After inserting the epi pens and putting it in the outer cover, we kept it in the outer mesh pocket of a backpack.It seems counterintuitive, but in order to work, it needs air flow. Do not put it inside a backpack and DEFINITELY not inside an insulated case (I tested this and it got hot quickly). You could put it inside a breathable bag, like a canvas tote, but I found the mesh outer pocket ideal (the pocket usually used for a water bottle). Bonus is that it is also easily accessible in an emergency.TSA did pull me aside in Boston's Logan airport but had no issue after looking inside. Another TSA agent called me aside after I got through and I thought it was going to be a thing but instead she just wanted to know where I got it because it was so clever.These will work best when it's less humid, but it did seem to handle 70% humidity ok. I would pay close attention if the humidity was much higher.

Product description is accurate. As long as instructions are followed and timing placed into ice cool water and timing taking out to dry. As well as the timing getting it into the sleeve. It does in fact keep the insulin cool enough to survive in the heat. Great for travel. Just make sure not to put it into an enclosed compartment. It needs to be able to breathe.

I used Frío cooling product while traveling overseas the bag was filled with water the first time and it lasted for 4 days, it would lasted longer, but I added water for the second time this Frio cooling product lasted for almost 10 days with only one refresh. It was in the sun and out in the element on my backpack. I make sure it was breathing all the time. Thank you very much for keeping my life saving medicines in great conditions. I am very grateful. Thank you

Past reviews complain about the temp. FRIO says it keeps cool to 68 degrees. It is not a refrigerator. We used in HOT Florida (July)at Disney and it kept our insulin from “cooking.” Insulin is working as it should. Now it’s on its way to HOT Cairo!

I got one a few years ago after I lost a pair of epipens when they got moved out of the shade on a hot day accidentally. While it does make the bag heavier, it's a huge piece of mind to know that my expensive rescue meds will be safe and not destroyed by heat should I need them!Someone in one of my Latex Allergy groups recommended the Frio Large Wallet for this sort of purpose and we double checked that it kept the right temperature for an EpiPen (where you don't want it as cold as insulin can be stored in) and, when there was an Epipen shortage and I had to get another brand, Impax, that was taller and thinner it still fit the case!I don't use mine often, so it's usually stored dry inside my house, but whenever I need it it charges up so simply and then I set it in the air to dry out after and pack it away :) Last summer it impressed everyone with how I filled it on a Friday and after the outdoor college graduation on Sunday in a heatwave so bad that at least 3 people collapsed and needed medical care, my epis were perfectly cool to the touch... And again during an outdoor funeral reception in another heat wave, when someone's bag with their epis got left in the sun and another relative made the rounds to see whose it was, neither of the other epi users had a cooling case and both spend a lot of time outdoors in the summer or in Puerto Rico at any time of the year with family, so they both know the pain of losing epis to the heat! Both rushed to order one!
