There's a small, slightly battered case that has sat under more aeroplane seats than I can count. It has been wedged into overhead bins from Toronto to Tokyo, tucked into the basket of a motorbike taxi in Hanoi, and balanced on the edge of a boat somewhere on the Mekong at five in the morning while the river turned gold around us.
It is not glamorous. It has a scuff on one corner from a luggage carousel in Lisbon that I've never quite forgiven. But it has been to roughly forty countries with me, and in all that time — through delays and downpours and the particular chaos of international travel — it has never once failed to do the one thing I need it to do.
Keep my insulin safe.
I'm a Type 1 diabetic. I've been managing this condition long enough that it's simply part of how I move through the world. And the insulin cooler — unremarkable as it looks sitting on a hotel nightstand or poking out of a daypack — is as essential to that as my passport.
This is a love letter to my insulin cooler. Bear with me.
What It Means to Travel Knowing Your Insulin Is Safe
Before I had a cooler I actually trusted, travelling with insulin was a low-grade source of anxiety that never fully went away. I'd find myself thinking about it at strange moments — in the middle of a museum, on a hiking trail, sitting at a restaurant trying to actually enjoy a meal. Is it too warm? Is the hotel fridge keeping it cold enough? Did I pack enough backup pens?
That background hum of worry is something a lot of Type 1 diabetic travellers will recognise. And it takes up more mental space than you realise, until one day it's gone.
The first time I travelled with a proper, medical-grade insulin cooler — one I genuinely trusted, not just hoped would do the job — something shifted. Not dramatically. Just quietly. The background hum faded. I stopped doing the mental calculations mid-museum. I looked at things properly, for maybe the first time.
That sounds like a small thing. It isn't.
The cooler I've relied on most over the years is the 4AllFamily Explorer 3-in-1 Insulin Cooler.
The Places We've Been Together
My cooler has sat on the windowsill of a riad in Marrakech while the evening call to prayer echoed off the walls. It came with me on a three-week trip through Vietnam during the rainy season — surviving humidity that turned my hair into something genuinely alarming. It spent a week in Iceland in the back of a campervan, somehow managing to stay at exactly the right temperature while outside it alternated between sun and horizontal sleet, which is apparently just Icelandic summer.
It has been to places that don't have reliable electricity, places where the nearest pharmacy was hours away, places where explaining "I have Type 1 diabetes and this is my medication" required a combination of broken French, hand gestures, and a translation app running on 2% battery.
In all of those places, it did its job. My insulin was cool. I was fine. We carried on.
There's something quietly remarkable about that kind of reliability — a piece of equipment that simply works, in every climate, every context, without fuss or fanfare. As a Canadian, I've been through enough weather to appreciate anything that just keeps going regardless of conditions. My insulin cooler and a good winter parka have more in common than you'd think.
The Moments I'm Glad I Had It
Not every travel story is a sunset. Some of them are midnight realisations and scrambled contingency plans and the particular cold feeling in your stomach when something goes wrong far from home.
The time a checked bag — not the one with my insulin, thankfully, but the one with everything else — went missing between Montreal and Frankfurt and took four days to reappear. In those four days I was very glad my insulin had been on my person the entire time. That lesson was free. I've met people who learned it the expensive way.
The night in a small guesthouse in rural Portugal where the power cut out at 10 p.m. and didn't come back until morning. No fridge. No outlets. Just my cooler, the cooling packs I'd refreshed that afternoon, and the knowledge that I had enough buffer to get through the night comfortably. I slept fine. My insulin was fine. The power came back at 6 a.m. and I made myself a coffee and watched the village wake up.
The morning in Southeast Asia when I pulled out a pen and noticed the insulin looked slightly off — not quite cloudy, but not quite right either. Changed insulin colour or clarity is a sign it can no longer be used safely. I switched to a backup pen. Because I always travel with backup pens. Because forty countries teaches you to always travel with backup pens.
None of these stories end badly. That's the point. They don't end badly because the cooler held, the backups were there, and the preparation held up under the pressure of real travel.

What Forty Countries Actually Teaches You
Here is what I know now that I didn't know when I first started travelling with type 1 diabetes:
The logistics, which feel enormous at the beginning, become ordinary. Not quickly, but steadily. Packing your insulin supplies stops being a stressful checklist and becomes just part of packing. The security routine at the airport — the letter from your GP in your carry-on, the cooler going through the X-ray, the occasional pulled-aside moment that passes without incident — becomes unremarkable. You stop dreading it.
What takes its place is something that's harder to describe. A kind of settled confidence, maybe. The knowledge that you have done this before, in harder conditions, and it worked out fine. That your cooler has been to thirty-nine of these places already and has not once let the insulin down, and there is no particular reason to believe today will be the exception.
That confidence is worth something. It makes the trips better. It keeps you present — actually present, in the place you've travelled to — rather than half-distracted by logistics you've already handled.
My cooler doesn't know any of this, obviously. It is a cooler. But I notice, when I'm packing for a trip, that I reach for it first. Before the clothes, before the guidebook, before anything else. It goes in first. Everything else gets arranged around it.
That's probably the clearest way I can tell you how much I rely on it.

For Anyone Who's Just Starting Out
If you've recently been diagnosed with Type 1 diabetes and the idea of international travel feels like something that's been taken away from you — or at minimum made vastly more complicated — I want to be straightforward with you.
It is more complicated. There's no version of this where I tell you it isn't. There are things to sort out, and things to carry, and things to know before you go. There are conversations to have with your endocrinologist and forms to get from your GP and a security routine to learn and a cooler to invest in.
But complicated is not the same as impossible. And it is not the same as not worth it.
I have stood on a boat on the Mekong at dawn with my insulin cooler at my feet and watched the light change on the water. I have hiked in Iceland and eaten my way through Portugal and sat in a medina in Morocco as the day wound down around me. I have done all of this with Type 1 diabetes, with insulin that needed to stay cold, with a cooler that made sure it did.
The complications fade into routine. The places stay with you.
Get a cooler you trust. Learn the routine. And then go.
