Here's the best insulin travel cases in 2019, that can help keep your insulin cool. Their benefits, disadvantages and where to find them for purchase.
Insulin Travel Cases

When it comes to travelling with insulin, the one thing we need to sort before we start planning anything else is how to make sure our insulin is cool whilst travelling. Insulin is the drug that keeps us alive and helps us regulate our blood sugar to ensure we enjoy traveling, so without ensuring it stays at the required temperature, our insulin will die.

Insulin, like other medications to treat chronic illnesses, are sensitive to heat and need to be stored at a temperature of between 2 to 8-degree °C

So, a good quality insulin travel case is the way to achieve this.

I’ve spoken lots of times about ways to keep our insulin cold when travelling, but I’ve mainly put my focus on Frio bags.

I still believe Frio bags are fantastic, but I thought I’d venture out on the internet and search for other varieties of diabetic coolers for insulin that may be on the market.

Low and behold, I found a few other products, so here is a complete comparison of all the insulin travel cases I found on the web and the benefits of each!

PSSST, do don't go travelling without medical ID!

1. BreezyPacks

What are BreezyPacks?

Looking for an easy breezy insulin travel case that keeps your insulin cool? Then look no further.

The BreezyPacks are cute, small cases that can hold temperature-sensitive medicine, i.e. your insulin!

They work by using a unique chemical that absorbs energy when the temperature is hot outside and actively cooling the content of the case (PCM). When the temperature drops, the PCM regenerates by itself.

What this means is you can simply pop your medicine inside and it will continuously be protected without a time limit. This is because the case recharges itself every night (pretty cool!)

They need to be at a cooler temperature to recharge (24°C/75°F or less) or, you can also pop them in a fridge for 1-2 hours to quicken the process)

The fact that you can keep reusing this product means that it's a worthwhile investment and means you'll get great value for money. Your insulin will be protected on all your future adventures.

I also love that its made with recycled and eco-friendly materials, a VERY important feature in todays world! 

There are currently 2 models on offer (with more in the pipeline).

The BreezyBasic and BreezyPlus.

The basic can protect your insulin in a hot day for 6 hours , and the plus for 9 hours.

**note this was tested at 38°C/100°F, away from direct sunlight**

Both of them fit about 2 insulin pens, and I'm not sure on insulin vials yet, but I'll let you know when I know!

The "plus" model can withstand even extreme climates, surviving entire days in the heat and temperatures of up to 46°C/115°F for shorter durations which is perfect if you're off on an adventure hike, or even taking a trip in the Amazon rainforest (this would have served me useful back on my Brazil backpacking trips!)

I'll have a full review of the product soon which I'll link to when it's ready, but what I REALLY love from first impressions, is the fact that there is no issues or complications or annoyance with "setting" it up, basically because it doesn't need any. You don't need to dip it in water (like a Frio bag), or charge it, or even refrigerate it, and that's really cool, especially for someone like myself who likes things to be easy, breezy....;) 

Another great thing is they deliver worldwide which is useful!

I think this looks like a great placed product for day trips with diabetes, trips to the beach, camping trips, hiking adventures, or city breaks.


  • Easy to pack size
  • Continuous use (recharges itself at night)
  • There is no faff, you don't need to dip in water, freeze, or do anything for it to work!
  • Recyclable materials and good for the environment
  • 3 year guarantee (that shows confidence!)


  • Holds a smaller amount of insulin (this is coming from someone who goes on VERY long trips, so I think for the average diabetic taking an average trip it would suffice!)-- I know they have a BreezyMega coming soon which will be perfect for longer trips.
  • If I find any cons when I test the product I'll pop them here

2. VIVI Cap - Insulin Cooler Travel Case - Keeps Diabetes Medicine Pen Safe

What is the VIVI Cap: Thermal Insulin Pen Carrying Case?

If you use insulin pens, rather than insulin vials for an insulin pump, then this is the PERFECT product for you.

This innovative product allows you to keep your insulin pen safe whilst on your travels, so it won't overheat or freeze.

Some highlights of the product include: 

  • Works every day for years with no maintenance: This product is an investment into your insulin cooling future. You won't need to replace it, it won't go "moldy", so you can feel confident it will continue to work for you when you need it most.
  • Built-in temperature sensor with easy to read temperature indicator: This is a very cool feature that will actually let you see the temperature that your insulin is at. This takes away the guessing game, so you can always be sure your insulin is cool when traveling.
  • Small & lightweight: This product is not going to take up valuable space in a backpack, suitcase or even handbag. It's small enough to fit in your purse, so perfect when you're sightseeing in the city, or heading out for dinner.
  • No need for water, ice packs, refrigeration or battery charging: a fuss-free product for those with insulin pens! 

I am actually in the process of reviewing this product, so I will add even more thoughts soon, but on first impressions, this seems like an excellent product, especially if you're a frequent traveler like myself.

It's perfect for taking your insulin out for the day, say if you're heading to the beach, or even going on a day-hike, day excursion, whatever it may be.

You can pop your insulin in the VIVI Cap and be sure it's going to stay safe!

A great product to add to your diabetes packing list.

Go ahead and buy it here! 

3. The 4ALLFAMILY 72 hour Insulin cooler travel


This insulin cooling case is actually pretty cool! The guys at 4AllFamily have sent me one to try out. This is basically an insulin cooling device that is in the form of a stainless steel cup.

What I actually love is that it looks like a coffee cup, so doesn't look "medical" which is something I always try to avoid when choosing insulin cooling cases.

It actually works in two ways: Firstly there is the Biogel bottle, which you can refrigerate for 6-8 hours in advance then pop it in your cooling case along with your insulin and cover it up! OR, when you have access to electricity, you can put the insulin into your vacuum

bottle and cover it with the black cooling cap. You then connect it power with the USB (have it on 30 minutes before you put your insulin in).

This combination of two ways to keep your insulin cool from one device means it's a perfect travel companion. You're able to keep your insulin cool when you don't have access to a fridge, THEN when you reach electricity, you can switch to the USB.

I think that's really cool! 


  • Can keep your insulin cool up to 72 hours
  • It's versatile and offers a variety of cooling methods in one product
  • It can be used with in-car 12V when adapted to a USB so a brilliant option for road trips! 
  • Comes with a 1 year warranty


  • They only seem to have it in blue (which is nice, but maybe not for everyone)

4. Medicool

The next insulin travel case I want to look at is Medicool.

Medicool actually is a website that houses a whole host of different insulin travel coolers and cases, so I’ll go through the ones I discovered on my searches and weigh up the pros and cons for traveling with type 1 diabetes.

Dia-pack: This is an insulin cooling case with a unique twist.

Not only is this insulin travel case fully insulated, but it comes with an electronic temperature display that reads the outside temperature! How cool is that? Pretty cool I thought. This product can keep your insulin cool for up to thirty hours, and it has the ability to carry needles, syringes and other medications you may require. It includes a re-freezable gel pack, meaning it can be reused, and a shoulder strap, which I guess is convenient if you want to hold it in your shoulder.


  • Keeps your insulin cool for up to thirty hours. This is good for flights, long car journeys, or even an overnight stay camping, at a hostel with no fridge etc. It’s also good for 24-hour bus journeys, but honestly, I ain’t going to recommend you even take one because they are so uncomfortable!
  • Comes in a range of different cases to suit different occasions, the elite, classic, deluxe and the day mate which is perfect for those day outs.  You can buy replacement gel packs to reuse the cooler


  • They don’t seem very “fashionable” and not a lot of different colours on offer. You have to pay for replacement gel packs which means extra expenses to reuse

5. Poucho

They are activated via water and are great for keeping insulin safe when it’s not being refrigerated.


  • It’s activated by water so pretty convenient when your travelling with diabetes
  • It can be re-used hundreds of times, which again is perfect for when you are on the road a lot
  • The cooler stays cool up to four days, which is good for city-breaks, camping trips etc
  • There are 6 different sizes to suit your insulin requirements.


  • There isn’t a lot of colour choice of product
  • 4 days isn’t as long as other products

But honestly, I think this is a pretty decent product, and perhaps I’ll get the chance to try them someday, but they are essentially the same as Frio bags, but Frio bags stay cooler for longer, which suits me better when I am travelling long-term, but these are a great choice if you are heading off on holiday!

6. The MediCool Insulin Protector

This is probably the least favourite of the insulin travel cases I’ve come across, not because I don’t think it’s useful, but I don’t think it’s a good choice for travelling with type 1 diabetes.

But, let's consider and look at the details.

The Medicool Insulin Protector Case can keep your insulin cool for up to 12 hours, so it’s definitely a good choice for a long road trip or flights or even a long day out at the beach. The problem is, it only holds up to two bottles of insulin, which really means, it’s not suitable for long-haul trips.

Two bottles of insulin would typically last me, around 20 days, give or take, which of course is fine for a 2 week holiday, the only problem is, that leaves me no room for spares, and it’s imperative that you take spares with you whilst travelling with insulin.

However, if you are on a short-term trip, then maybe this is the choice for you. It also comes with two cooler packs so you can refrigerate one whilst using the other. You can get it here.


  • Good for a short-term trip or day trip


  • You can’t carry more than 2 bottles of insulin
  • Doesn’t fit pre-filled insulin pens
  • Not a wide range of styles
  • Looks bulky and ‘medical’
  • Overpriced for what it is

It's a little small!

7. iCool Prestige

This product keeps your insulin cool for 12, 24 or 36 hours, (depending on which version you buy), but it can be reactivated for another 24 hours, and so on so forth. 

The thing I really like about this product is that it has the space to organize around three weeks supply of your medication….which is a really great amount. Therefore, for example, if I am heading off on a trip to live in Austria for a month, (which I did), then it will keep my insulin cool until I arrive there and transfer it to a fridge, and it will have the amount of insulin I need!

However, it is an expensive choice coming in at 65 euro. But as far as insulin travel cases go, I’d say this doesn’t seem like a bad one.

They also offer a range of small cool bags for medication too, which means you can find something to suit you. But, it doesn’t have a wide range of colours and looks a little clinical. (I’m not sure if you have realised but I don’t like things looking clinical!)

8. Frio bags

Last, but by no means least, I’ll give a review of Frio. As you might well know, this is my product of choice and I have used it for 4 years now, (the same bags), and I have never had any insulin die. I think this reflects just how well they work. For me, they work even better than they actually recommend!

So, what are Frio Bags?

If you haven’t already checked out my other babblings about Frio, then you might not know that Frio bags are a device that keeps your insulin at the required temperature when you don’t have access to a fridge, so either flying, camping, hiking, etc.

The Pros

  • Frio bags keep your insulin cool and safe, the required temperature for in-use insulin is 18 to 26 degrees, and this is exactly the temperature that Frio bags aim for.
  • They look good. I don’t think Frio bags cool “clinical”, which is one of the main reasons that I like them. I don’t like to look clinical, I like to look fun, and their awesome range of colours mean my diabetes can stay cool in purple and pink tones.
  • They come in a range of sizes.
  • Small Double which will fit two pens
  • Large Wallet which will fit 10 insulin vials or around 6 pens. I fit in around 12 vials in my case.
  • Extra Large Wallet which will fit around 15-17 vials for me
  • Sometimes I need one Frio bag, sometimes I need two...and on a three-month trip, I need three! I like that you can get a full range of different sizes to suit your trip. (I also like that I can fit in more than they recommend! :P)
  • Frio wallets can be reused OVER AND OVER again! The Wallet can be reactivated and used for subsequent periods of 45 hours minimum for up to 28 days- however, I have used mine for over three months at one time and I have never encountered any issues.
  • They are so simple to use: you simply activate them with cold water- nothing fussy! They say they last up to 12 months or longer, depending on your usage, but I have had my oldest Frio bag for three years and it’s going strong.

Frio can hold pens, vials and emergency medication! 

I personally think Frio is the most reasonably priced for the style, quality and use you get from them! 

Plus, you can shop around on Amazon, and other outlets to compare prices to find a cost that suits you- either way, you're still getting a Frio bag!

I’ve purchased one of mine direct of Frio, one off Amazon, and another I was given to review by Frio themselves (Thank you!) I used them before I got given one to review (it was their newest design), so that doesn’t make me biased BTW! :P

I really can’t give any major cons to the Frio bags, because it’s the thing I use every time I am travelling, so if I thought there were any major concerns I wouldn’t use it! They also have their newer Insulin Travel Case which has multiple compartments to hold all your Frio wallets, diabetic supplies and a sharps bin.

They are have a beautiful range of wallets that are fashionable and stunning! Check out mine here.


You can get an exclusive 20% off when you purchase the eBook or course.

BONUS: The MedAngel One

This isn't a insulin travel case, rather it's a sensor that helps you track whether your insulin is at the required level to stay alive. It's a really cool sensor you pop into your fridge, or beside your insulin, or inside your chosen insulin cooling wallet and it can test if you insulin is too cold, too warm, or just right!

This is a perfect device for travelling to destinations that are known for their heat or cold and great for if you are backpacking and using dodgy hostel fridges. It tracks your insulin via an app on your phone and right now you can get a generous 20% off a sensor when you purchase our eBook or course. The sensor battery lasts for nine months, and it can be replaced so can be used for as long as you need it!
