Frio Extra Large Insulin Cooling Wallet - Keep Medication Cool for 45+ Hours Insulin Bag - Perfect for Travel and Everyday Use

These Frio Insulin Cooling Cases have been life savers for me while on vacation or other travel, especially if I am staying in accommodations where there is no refrigerator, which is usually the case.I have a variety of different size cases, depending on how many insulin epi pens I need to take with me.These cases do a great job of keeping my insulin epi pens at a 'safe' temperature to prevent them from spoiling.They work using evaporation to keep the epi pens cool.The case consists of two bags made of ‘breathable’ fabric. The inner bag contains crystals, locked in place, which when the bag is immersed in water for several minutes, will expand and absorb a lot of water. The inner bag is then placed in the breathable outer bag, both of which have Velcro flaps to keep them closed. When the water held by the crystals slowly evaporates from the inner bag, heat is removed from the epi pens, keeping them cool and at a safe temperature so the insulin will not spoil and go bad.It is important to keep the cases in a place where the water can evaporate (when the water evaporates, heat is pulled away from the epi pens) and cool off the epi pens, so don't for example keep them in a plastic zip lock bag, for example, or other non-breathable bag, as the water will not be able to evaporate.I keep my cases in the mesh water bottle holder of my back pack. However, I find it a good idea to use a safety pin through the outside case to secure it to the webbing on the water bottle holder to ensure it does not fall out.These cases have resolved a huge problem for me -- how do I keep my insulin at a safe temperature while traveling when I do not have access to a freezer so I can refreeze the ice packs that I normally carry with me to keep my insulin cold when I am not on vacation?.The cases can be reused many, many times by re-immersing the inner case in cold water, allowing the crystals to absorb more water.They will not last forever. After a couple of years, the crystals will absorb less water and the cases will need to be replaced.Note that some reviewers have criticized these cases for not keeping the insulin colder. I have found they will keep insulin at a temperature of 68 degrees or so when traveling in temperatures of about 95 degrees. These will not keep your insulin as cold as if they were in the refrigerator, but the insulin in an epi pen, once you start using it, should be stored at temperatures in the 60's / low 70’s anyway (please read your insulin makers instructions for what temperature they should be stored at).

Kept my medications cool for a very long flight. I would recommend getting this one because it did not fail me. Perfect for traveling long distances and you can also have your meds in bulk.

I used this item once. Followed the instructions and it molded after the first use. It wasn't left inside anything or anything done that would've promoted the mold.

The product is true to its promise!

Not just for travel, but at home for convenience. I use two meds that have to be kept below 85F, insulin plus a GLP-1 injector. I use a small wallet for the insulin and this larger one for the injector. The larger one also serves to hold back-up meds when traveling. simple, easy, and effective.

These are very handy! You can keepMedicine close by at home it while out and about. It’s an easy way to keep your medicineSafe & ready to use. This one is a size bigger than K thought it be but still works very well’Have used a FRIO for many years!!!

This product really did work. It stayed cool for 48 hours..

I got the biggest, since I have multiple things I need to keep cold.As far as it goes, the process isn’t too difficult, and the instructions are simple. However when I was soaking it, the water was turning red from the dye used for the fabric. And this wasn’t just one or two passes, even running it under cold water it was still leeching dye. Definitely can’t keep this next to fabric items.Functionality, yes it kept it ‘cool’ but not actually cool enough for meds. On top of that, it stays damp. In a place where the air is humid I can imagine mold growing because it really does stay damp like that.
