Lots of caffeine today, so long reply
I live in a hot climate and travel to hot climates. My cooling device recs are below, but one thing I will add is also don’t forget to pack something for if you get nauseous or dehydrated in the heat. Being severely dehydrated and having to deal medical staff in foreign country is an experience I never, ever wish to duplicate again - so now I never travel without some sort of powdered electrolytes/rehydration packs now.
For cooling recs:
Like others above, I’ve used Frio for years, and they have seen me through many, many trips on multiple international destinations with no fridge at all. Tip: take a few shapes and sizes and bring several “non-activated” (read: dry) spares with you. More on that below.
Lately in an annoying trend, in some airports I’ve noticed on the past several flights I’ve taken that I’ve been getting flack from uninformed TSA agents who try to tell me I cannot have gel packs that aren’t completely frozen.
So I’ve started doing a few things differently in particularly irritating airports, I will pack my “dry/non-activated” Frio packs in my backpack, but will bring all the insulin in a plastic zip lock gallon freezer bag until I’m through security. Then after security I will immediately activate Frio packs with cold in large plastic cup (yes, bring extra paper towels just in case) - eg all after I’m through security but before boarding. I did this for a long, surprisingly hot plane ride too/from/through southern Spain and it worked great.
For US flights: If the Frio gel packs are already activated before I go through security - and if get any s*** from the TSA agent, I’ve started carrying a print out from TSA web site page highlighted in bright yellow the section that says "Note that medically necessary gel ice packs in reasonable quantities are allowed regardless of their physical state of matter (e.g., melted or slushy) with or without the presence of breast milk. Please notify the TSA officer at the checkpoint for inspection"
Gel Ice Packs | Transportation Security Administration (tsa.gov)
They either look baffled and apologetic and let me through, or they just give a hard stare and warn me for next time.
Caveat - this may/may not work in some US airports, depending on level of “stern” [read: a****le!) of said TSA agent. On one unpleasant occasion the TSA agent threw away my Frio gel pack, but handed me the insulin. Hence the reason for carrying a few non-activated/dry spares in the backpack.
Don’t Do This: Also, I do NOT recommend arguing with or getting cheeky with ANY agent in ANY international airport, particularly those where guards are armed with machine guns.* Just sayin from personal experience - that was looooong afternoon
More Cooling Recs:
When going to very hot climates, in addition to Frio, my all-time favorite combo is my Artic Zone combined with the [AllFamily Nomad] which is small and stays frozen for several hours (Portable Cooler for Insulin & Medications – 4Allfamily)
My other go to is the [Tourit Cooler Backpak] many times
I use the backpack with either my Nomad above or with the [Fridge to Go)] which is smaller and lightweight, good for shorter flights
Also have the AllFamily Voyager, but its way heavier, good for longer trip/ and cooling fan has been helpful for situation with no fridge/ no AC - which I pack in my larger suitcase . This can be a pain to carry but worked great for several hours on the beach in the hot sun.
I’ve found most of the foreign hotel have been very kind when I ask them to refreeze the AllFamily - just remember to get it before you leave the hotel
Hotel Fridges are unpredictable! note on Frio - if the gel is activated, I do NOT recommend storing them with your insulin inside in ANY hotel fridge. I’ve had the Frio crystalize and freeze in two hotel fridges in the US - and the insulin was ruined. Thank god for the amazing pharmacist at Walmart down the street who sold me some Regular and NPH with no prescription and no questions asked.
Have a great trip!
