FRIO Insulin Cooling Wallet, Red, Large by FRIO

I haven’t used the product left as we are traveling internationally in 3 weeks but I can tell this will be perfect to take 4 Mounjaro pre-filled syringes with me on the trip. I was looking for something that would keep the pens cold during our travel and this is perfect. No ice packs needed, simple to use and easily fits 4 pens in the pouch. I will come back and give an update after our trip. But I think it will be perfect! Arrived quickly and seems to be a quality product. The color is pretty and will be easy to spot in my personal item.

Good product, it kept the cartridge cool

Frio Cooling Wallet Item(s) Qty Price Total 1 $ [...] $ [...] FRIO LARGE Insulin Cooling Carrying Case / Wallet - Evaporative Cooler - keeps insulin cool up to 45 hours without ever needing ice packs or refrigeration! I received item, attempted to get it to work. I followed instructions about soaking time, spreading out crystals, etc. Before I potentially ruined a bottle of insulin I wanted to verify bag works. I did not at any time place a bottle of insulin into 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:mm Room temp = 80F Bag temp = 78F Time = 00:15 Room temp = 80F Bag temp = 78F Time = 00:45 Room temp = 80F Bag temp = 78F Time = 01:30 Room temp = 78F Bag temp = 76F I did this for over 48 hours. The data showed that Bag temperature was around 2 to 3 degrees cooler than Room temperature. So if Room Temperature never dropped below 85F, then Bag Temperature would never drop below 82F. If you are trying to "cool down" a bottle of insulin, this bag will 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 this info from : [...] Even in Hot Climates! Insulin must be at the manufacturer's recommended 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 at the time of purchase was that this bag "cooled down" a bottle of insulin. "Cooled down" is my phrase, not Frio's phrase. Does Frio keep an already "cooled down" bottle of insulin cool 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 64F when the Room temperature is 80F? Definitely not! I can state this without reservation that the bag I bought does not "cool down" a thermometer to anything approaching 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 was not going to be near refrigeration. I was not going to be near anything that would act like refrigeration (ice, snow, etc).

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.

Didn't work for me because of the pouch size. I needed more fabric stretch flexibility.
