Wondering whether the 8K Flexwarm heated jacket is worth buying?

Keep reading and I will give you my full review of the 8K Flexwarm jacket and whether I think it’s worth buying.

I’m one of those people who seem to be cold a lot whether out hiking in the hills or sitting watching TV (currently sat wearing two jumpers at home). Are you nodding along in agreement?

When 8K Flexwarm asked me to try their women’s heated jacket I thought I would be a great person to review it and give it a thumbs up or thumbs down. I’ve tested the 8K Flexwarm jacket on my hiking and outdoor adventures, mainly during the winter months.

Please note, although I am reviewing this jacket on behalf of 8K Flexwarm, all thoughts and opinions about the jacket are my own. I will give you the good and the bad (that’s if there is any)!

Who is 8K Flexwarm?

8K-Flexwarm Heated Jacket

The company 8K Flexwarm, is, in fact, two companies combined, bringing together their skills to produce heated jackets.

The jackets are designed and created in Europe and are now on sale all around the world with FREE worldwide shipping. Although I’m sure some tropical countries probably have no need for them!!

They have created stylish jackets that use no down or fur to keep you warm, instead, there is smart technology to literally heat you up!

What Features Does the 8K Jacket Have?

Luckily it had warmed up so I could take the 8K Flexwarm Jacket off for a photo!

The jacket is a lovely fit, I felt comfortable as soon as I put the jacket on and I reckon it’s pretty stylish too. A word I don’t normally use to describe myself haha. Well, I will let you make your own mind up from my photos.

The jacket is made with an inner breathable fabric, cotton insulation in the middle, combined with the Flexwarm technology and on the outside is a water-resistant fabric.

Other all-important features of the 8K Flexwarm Jacket

Zipable pockets 

  • There are two side pockets both with zips and perfect to pop your hands in to keep extra warm against the heat panels.

Fitted inner sleeves 

  • One feature that the jacket has that I love is the inner sleeves.
  • They are snuggly fitting stretchy sleeves that stop cold wind from blowing inside your jacket.

Double zip 

  • There is a double zip, so you can zip the jacket up or down depending on how warm or cold you are.
  • It’s not a feature I thought I would use but it is handy if you want to keep your neck warm but unzip from the bottom of the jacket. 

Heated panels 

  • Ok, so this is really the most exciting feature. I’ve never tried a heated jacket before so I was intrigued about this feature.
  • There are heated panels in the front and back of the jacket, keeping you toasty and warm.

What Size Does the 8K Flexwarm Jacket Come In?

I am a size 10 women’s for my hiking jackets and clothes and generally wear a size S (Small).

However, the jacket size I received was an M – (Medium). Before I tried it on I thought the jacket would be too big but actually, the M size is a perfect fit for me.

Based on the size I received I would recommend choosing a size up from what you normally are, for example, I normally would select an S but the M was the best size for me.

The only thing I would mention is that I found the length of sleeves a little short for me personally, I’m 5″7, but nothing that I good pair of gloves wouldn’t solve!

The other sizes available are:

  • 14-16 Girls
  • XS
  • S
  • M (My Jacket)
  • L
  • XL

The jacket fits perfectly under a waterproof jacket, which is handy in heavy rain!

How Much Does the Heated Jacket Cost?

The 8k flexwarm jacket price for the women’s jacket is £219, however, at the moment the orange jacket is on sale, woohoo!

Check here for the latest prices.

There are also two other women’s heated clothes available – a Gilet (Body Warmer) and a Hooded Jacket

Also included in the jacket is a FREE power bank (spare power banks can be ordered). I’d recommend buying an Anker one from Amazon as the 8K Flexwarm ones seem more expensive than like for like products

The jacket is FREE shipping worldwide, who doesn’t love free postage!!

*All prices are correct at time of writing 🙂

What Colours Are Available For The Jacket?

As you know I know I love my bright colours but unfortunately, the colour I initially wanted wasn’t in stock which is why I opted for the navy blue.

The colours available are:

  • Navy Blue
  • Black
  • Orange

How Easy is it to Use the Heated Jacket?

When the jacket arrived I expected a leaflet with the instructions on how to use. I couldn’t find it anywhere, then realised all the useful information is written on the cardboard label haha.

First, put the Power Bank on to fully charge. Once it’s charged up, you pop in the inside pocket and plug in the USB. Don’t worry if it’s dark because the handy power bank also has a bright torch.

Read my tips about using a smartphone in the mountains here.

The jacket also comes with a 2-year warranty, simply register online when you receive the jacket. You literally fill in name, email, product code and it’s done (I’d recommend doing before you lose the code haha!)

Oh, and did I mention this jacket can also be activated via the Flexwarm App, available on Android and iPhone.

I’ve not used the App much yet as I prefer manually turning on but I can imagine it will be handy when wearing another jacket on top.

My First Time Wearing the 8K FLexwarm Jacket?

An autumnal walk in the Lake District

The first time I wore my 8K Flexwarm was on a sunrise hike in the Lake District. I was in the Lake District for the Kendal Mountain Festival in November but opted to do the Kentmere Horseshoe hike whilst I was there.

Instead of getting up early, we opted to get up super early and watch the sunrise. As you can imagine, getting up in the dark at 5.30 am it was still dark and cold outside, brrr.

So straight away I could try out the jacket, how exciting!

You can control the jacket by either the buttons on the side of the jacket, on the left-hand side so slightly easier for right-handed users.

Although I’d downloaded the 8kFlexwarm App, for my first time I used the buttons to control the heating and hit the hottest setting for both the front and back panels.

The jacket heated up relatively quickly and was great as I was stopping to take photos on the way, stopping every few seconds because there was an awesome cloud inversion. But as soon as I started hiking uphill my body warmed up so I turned the jacket off.

Throughout the hike, I turned the jacket on and off, mainly when I stopped for snack breaks but I loved the instant burst of heat to warm me up.

One of my favourite things was popping my hands in the pockets since my hands tend to be like ice-blocks most of the time!

Where Could You Use the Jacket?

The first weekend I wore my heated jacket I was at the Kendal Mountain Festival. I initially thought I would use the jacket for hiking but it was fantastic to wear after coming out of a warm Town Hall to the cold evening after watching the ‘Best of Kendal Mountain Festival Film’.

I would say the 8K Flexwarm is perfect for most outdoor conditions, in particular:

  • Cold autumn or winter mornings (maybe walking the dog!)
  • Chilly evenings when the sun goes down
  • Stopping for snack breaks or lunch stops on your hike
  • Photographers setting up creative or night shots
  • Keeping you extra warm if you suffer an injury whilst hiking
  • A heat boost at the top of chilly summits or ridge walks

Would I Recommend 8K Flexwarm Jacket?

The 8K Flexwarm jacket is great for hikers but generally anyone who loves the outdoors too. As the weather starts changing in the UK it’s the perfect item to wear on your adventures.

In the autumn months, it tends to be colder in the morning and evenings as the sun disappears so the heated jacket is the perfect option to warm you up, instead of carrying extra layers.

Of course, winter is a no-brainer, it’s cold and if you want to be cosy and warm then this jacket is great.

I personally really like the jacket, it’s stylish so I can wear not only when I’m out hiking but also on evenings out as well.

One feature for those techy lovers is the Power Bank has two USB points so you can also charge your phone and jacket whilst on the go!

Buy your jacket now ready for winter brrr!

    This jacket sounds really awesome especially as I fall into both the “always cold” category and the photographer always stopping to take a pic. Considering it for the future! Thanks for a great review!

  2. Kelly says:

    What an amazing jacket! I had no idea heated jackets were a thing and live the in depth review. I wish I had this when I was in the Lapland region of Sweden!

  3. Anisa says:

    I didn’t know there was such thing as a heated jacket! What a great idea. It’s nice to have something to keep you warm that is not so thick. How long does the charge usually last?

    • Becky the Traveller says:

      Yeah me neither, well until I tried it! I switched it on and off during the day and didn’t use the full charge. I think it would be about 3-4 hours if it was on continually but need to test it out a bit more!

  4. Monique says:

    Hi There,

    Wondering if you can help me decide on the right size silly I know. I am from California and I am always freezing in high 70’s crazy I know but blood tests are all normal. I just ordered a Large but the arms are so tight I feel like I may rip the jacket and like to wear things loose due to my layers. Question- I am not familiar with European sizes (the brand is from UK) if I am 5’3 Large other than the arms fits perfectly but again I prefer a little looser for layers and my width of my arm is 17”, bust is 37.5 would you recommend Men’s Medium, or the Woman’s XL. I tried to email and chat Flex 8 but no reply yet and I need the jacket ASAP. Please help….I do appreciate any help I can get ….

    • Becky the Traveller says:

      Hi Monique, I’ve just checked my jacket, I’m normally a Small in ladies clothing but actually, have a Medium in the Flexwarm jacket. I would opt for the size up, so as you’ve mentioned the XL option. I hope that helps 🙂

  5. Monique says:

    Hi There,

    I just sent a chat asking for help about Flex 8 jacket I ordered (wrong size). Wondering if you can recommend a great base layers/sweaters to keep me warm. Generally I am always freezing and wear layers even in 80 degree weather. Any help would be greatly appreciate your help thank you in advance.

    • Becky the Traveller says:

      Hi Monique, yes, I have the same problem. I’ve recently tried Icebreakers which are merino wool and certainly kept me warm, I also have a Salomon down jackets which I love and packs super small and light as well so it’s great to take with me on trips 🙂

  6. Ken Roden says:

    I didn’t have much luck with this jacket. It worked on my first cool golf day. After that it wouldn’t hold a charge for more than an hour. Contacted the company and they told me “Sorry” You can buy a battery off Amazon. No warranty after one wear !

    • Becky the Traveller says:

      Ah I’m sorry to hear that Ken, it doesn’t sound great service. Mine is still working fine after 2 years so it doesn’t seem right, I would persevere with them regarding a refund or repair under the warranty.
