What people tell us after their first trip with it.
My daughter found this for me, I wasn't even looking. We flew to Phoenix in June and I spent that whole first flight checking my medication every hour like a crazy person... old habits I guess. By the second day I'd forgot about it, which for me is a big deal. Wish I'd had it years ago honestly.
Bought this for the drive down to Florida to see the grandkids. Used to be my ice packs turned to soup about halfway there and I'd be sweating it the rest of the way. Not this time. Easy enough that I figured it out myself and I'm no gadget guy, ask my wife ha. Only thing, kind of wish it came in another color, but that's just me being picky.
Honestly wasn't sure I needed one. Turns out I did. Only wish I'd found it before our cruise last year.
My daughter kept after me about leaving my medication in the car in summer, so she ordered me this. Been using it a couple months. I check that little screen more than I need to, but that's my own doing. Does what they said it would.
I was worried it'd be too small once the cold packs were in but there's room for four pens and I still had space. Took it to my sister's for a week, never gave it a second thought.
Went through security twice with no fuss, nobody even asked about it. Works exactly like they say. My only gripe is the wrist strap is too short to get over your shoulder, so it lives in my bag. Four stars for that alone.
The mini fridge in our room barely got cold, it was basically a cupboard. Would have been a real problem before. Now I just don't have to think about it.
First trip I put the cold packs in the wrong way round and it didn't hold as long as I expected. Read the little booklet properly the second time and it was fine. My fault not theirs, but worth knowing.
Two flights and a four hour layover, close to eleven hours door to door. Checked the screen when we landed and it was still where it needed to be. That's all I wanted from it.
Got one, then got another so there's one in the car and one in the travel bag. Sounds excessive, but I'd rather that than pack and repack every time we go anywhere.
Made for the in-between
Zardy was built for the stretches where there's no fridge, no ice, and no easy way to know — the ones that used to mean packing a bag of melting gel packs and hoping.
Fits pens, vials and cartridges. For anything temperature-sensitive, check the storage range printed on the packaging.
Two planes and a layover. Nothing on board is cold, and the galley was never an option.
Sun on the dashboard, a warm boot, and a car park with no shade in sight.
Cabins, guest rooms, spare beds — places where the fridge belongs to someone else.
Sometimes full, sometimes warm, sometimes a cupboard with a light in it.
Festivals, ballparks, back-to-back meetings. Out from morning until late.
Shift work and early starts, when the day doesn't line up with a kitchen.
Made for real trips
Pack it in the morning and forget about it. No melting ice packs, no hunting for a hotel fridge, no opening your bag every hour just to check. Just your medication, looked after, while you get on with the trip.
Up to 9 hours at 86°F in our own testing.
See the internal temperature instantly, without opening the case.
A hard shell that takes the everyday bumps so your medication doesn't.
Compact enough for backpacks, handbags and carry-ons.
What's inside
There's no compressor and nothing to plug in. Zardy holds its temperature the way a good flask does — by slowing down every route heat can take to get in.
A tough exterior that takes the bumps, drops and daily wear.
High-density foam acts as a barrier, slowing heat transfer from outside.
An aluminium lining reflects heat away and holds the inside steadier.
Tested to hold up to 9 hours at an ambient 86°F. Hotter surroundings and frequent opening shorten it — which is exactly why there's a display.
Protect your temperature-sensitive medication in two simple steps.
Open Zardy, place your medication inside, and close the case securely. It takes less than a minute.
Take Zardy wherever life takes you. Check the temperature anytime using the built-in display—without opening the case.
Most people make do with ice packs. Here's what changes when your medication has a case of its own.

The usual way
A note from the founder
I started Zardy after a trip where I spent more time worrying about a bag of melting ice packs than I did actually enjoying myself.
I'd packed my medication in a cooler bag, the way you're supposed to. By the second airport the ice was water. I spent the rest of that day guessing whether what I was carrying was still any good — and guessing is a horrible feeling when it's your medication.
So I went looking for something better. A case that just holds its temperature, and shows you it's doing it, without you having to open it every hour. I couldn't find one I trusted, so we built one.
Zardy does one job. It's small, it's not complicated, and there's nothing clever to learn. If it doesn't do that job for you, send it back — I'd much rather refund you than have you travel worried.

Up to 9 hours in our testing, at an ambient 86°F — enough for a long flight, a day of travel, or a hot afternoon in the car. Cooler surroundings stretch that further; opening the case often shortens it. You never have to estimate, because the display shows what's happening inside.
Chill the two gel packs, then slide them into their pockets either side of your medication. That's the whole routine — once they're in, the case looks after itself.
The display is there precisely so you can see. Most medication has a range it needs to stay within rather than a single temperature, and freezing is as much of a problem as heat. Check the range on your packaging, glance at the display, and you'll know where you stand.
It's sized for a carry-on and security staff see cool packs and medication every day. Keep it in your hand luggage rather than a checked bag — cargo holds get cold and your bag can go missing — and keep any pharmacy label with it.
Four pens sit in elastic loops, with the two gel packs in the compartment alongside. Vials and cartridges fit in the same space.
Yes — it reads the temperature within the case, so you can check without opening it and letting the cold out.
Wipe the inside with a damp cloth and let it dry fully with the lid open. Don't put it in a dishwasher or submerge it.
The case, two reusable gel packs, and a short getting-started guide.
