I have been searching the internet for how to keep my insulin safe while in an extreme cold climate. I use FRIO bags when travelling but have never travelled anywhere this cold before and FRIO say they can not guarantee their bags are safe in possible -20° weather conditions cos they’ve not been tested. We will be outdoors most of the time so will need my insulin with me but don’t know what to put it in. I thought this would be a quick search, a product widely used by T1’s would come up and I’d buy it but the best and only advice I’ve read is ‘don’t let your insulin freeze!’ How? Thats my question. (and shouting this at my phone hasn’t helped)
