FRIO Large 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.

This surprised me, and continues to do so. I activated it the day I received it, to test it. It has been left out to dry before I actually need it. It says it stays cool up to 45 hours. It is well over that (double plus) and is still moist and cool, and the crystals have so far stayed hydrated to at least half of their full capacity. This will be further tested when I actually travel in less than a month, and the weather is hotter and more dry.

Had to keep my insulin pens cool for a transpacific 24 hour journey. They were still quite cool when I reach my destination. No problem clearing them in carry on luggage thru Us TSA.

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!

Great gift for my wife. Carries on all our trips for her medication. Keeps her medicine in a safe tempeture range.

Frio Cooling WalletItem(s) Qty Price Total1 $ [...] $ [...]FRIO LARGE Insulin Cooling Carrying Case / Wallet -Evaporative Cooler - keeps insulin cool up to 45 hours withoutever needing ice packs or refrigeration!I received item, attempted to get it to work.I followed instructions about soaking time, spreading outcrystals, etc.Before I potentially ruined a bottle of insulin I wanted toverify bag works. I did not at any time place a bottle of insulininto bag.The only thing I placed in bag was a thermometer.I placed a thermometer inside bag. (bag temperature)I placed another thermometer outside bag. (room temperature)Start time. 00:00 hh:mmRoom temp = 80FBag temp = 78FTime = 00:15Room temp = 80FBag temp = 78FTime = 00:45Room temp = 80FBag temp = 78FTime = 01:30Room temp = 78FBag temp = 76FI did this for over 48 hours.The data showed that Bag temperature was around 2 to 3 degreescooler than Room temperature. So if Room Temperature never droppedbelow 85F, then Bag Temperature would never drop below 82F.If you are trying to "cool down" a bottle of insulin, this bagwill not do that.My understanding at the time I bought the product was that it"cooled down".I could not get it to do that.Much, much later, weeks later, I was able to extract thisinfo from :[...]Even in Hot Climates! Insulin must be at the manufacturer'srecommended temperature when placed in the FRIO wallet.I did not know that, prior to purchasing bag.If I had known that, I would NOT have purchased bag.I was led to believe from all the information I could find atthe time of purchase was that this bag "cooled down" a bottle ofinsulin. "Cooled down" is my phrase, not Frio's phrase.Does Frio keep an already "cooled down" bottle of insulincool for 48 hours?I don't know, I did not test that.Does Frio "cool down" a bottle of insulin?I don't know, I never put a warm bottle of insulin in bag.Does Frio "cool down" a thermometer to something like 64Fwhen the Room temperature is 80F?Definitely not! I can state this without reservation that thebag I bought does not "cool down" a thermometer to anythingapproaching near 64F if the Room temperature is 80F.That was my need at the time.I needed something to "cool down" a bottle of insulin. I wasnot going to be near refrigeration. I was not going to be nearanything that would act like refrigeration (ice, snow, etc).
