With already close to $2 million raised from its Kickstarter campaign, POLAR SEAL has created a revolutionary smart shirt that heats up with a press of a button. Designed for outdoor enthusiasts and athletes alike, the super lightweight PolarSeal top gives both women and men up to eight hours of continuous heat throughout the day.
Intelligent Design Features

Whether it’s a passerby storm hitting you while hitting the slopes or a sudden change in temps while hiking your favorite trail, the PolarSeal top keeps you warm when you’re feeling chilly. Without needing to carry extra layers to the ballpark during fall baseball, the PolarSeal top is super lightweight, made of flexible materials, and is designed for breathability. Available in both men’s and women’s sizes, POLAR SEAL designed its second-generation athletic top to be both fashionable and highly functional.
PolarSeal Technology
With three different heating levels (low: 104-degrees Fahrenheit, medium: 113-degrees, and high: 122-degrees), wearers can control their comfort level by simply selecting from three color-coded LED buttons. You’ll always know your chosen heating level whether you’re battling a blizzard or sitting through a rainstorm. The LED buttons illuminate nicely allowing for seamless adjustment between varying temps.
Powering the day-long heated shirt is a highly-versatile 10,000 mAh battery pack providing eight hours of continuous warmth (with both heating zones activated and on the highest heating level). POLAR SEAL engineered its heated top to work with a host of USB power banks – making its shirt one of the most compatible smart shirts on the market today. Wearers have complete control over their power source and don’t need to rely on one particular energy bank.
User-Friendly
Taking only 10 seconds to activate, the heat-on-demand top by POLAR SEAL is intelligently designed with state-of-the-art heating technology. According to the company’s Kickstarter campaign, the PolarSeal heating elements are strategically embedded between two ultra-thin dissipation layers – integrating seamlessly into the fabric of the shirt. The end result: a super lightweight, flexible, breathable, and water-resistant wearable that keeps even the cold-blooded toasty during the winter months.
Whether it’s mountain biking down your favorite trail on a crisp fall morning or finishing your company’s corporate 5K run on a rainy afternoon, the PolarSeal top is a water-resistant top designed for durability. The detergent-safe heated shirt has been tested in extreme alpine conditions in and around Mammoth Valley in California.
Highly Durable

Following the athleisure trend, the PolarSeal heated smart shirt is poised to disrupt the wearable industry. The outdoor apparel industry now has a top that keeps the athlete outdoors no matter how cold it gets or how rainy it becomes. Both men and women have the full spectrum of sizes designed to be both flexible and form fitting.

I would like to know why it is taking a month to get what I paid for? This is bull–it!
5 weeks to wait for 1 shirt is a load of crap.they sure take your money right away. Will never Ever order here again. And I will be posting this on Facebook as well. I will also post where ever I can about this piss poor customer service.
Ok ok, it took a while to come in. Idk if those complaining above realize that it was a Kickstarter. Production takes time!
Now for a review from someone that has actually used it…
Got mine in last week. I was a little upset it did not come with a power bank. I don’t remember this being stated on their Kickstarter site, but then again, I could have missed it. $16 and I now have a power bank. I’m happy with the size. I’m 6’3″ 200lbs and a large fits me well. Not skin tight like underarmor, but not baggy either.
When I turned the setting to high on the first use, you could definitely feel the heat through a t-shirt in under 10sec. Not too hot though. I’m impressed with how quick it heats up! I can’t speak to how long it’ll go for. I typically only turn it on for the chairlift rides up the mountain, and the power lasts all day for that. Really happy with the purchase. We’ll see how long it holds up!

The best investment I ever spent, ordered it in every color. Great for sore backs is as bonus!
To everyone slating the product due to shipping issues, let me advise you to re-evaluate what you are doing. You are reviewing a product, not the shipping company or the distribution network.
As such you reviews are off-topic. Mine took a while to arrive, however once it got here, the product is outstanding. The heating is great, battery life is fantastic and the material has a premium feel.
I have been wearing it under by winter jacket, and been out and about today for about 4 hours straight in freezing conditions, the top making it enjoyable and kept me going without having to carry coffee.
Great product.

I order my top and patiently waited, finally it is shipped. BUT they ship to the wrong address and with incomplete address(no street address) label, making the package undeliverable. At first they admit the problem and agree to replace, then they insist they shipped to correct address which was in a different. They refused to check they own tracking information and say there is nothing they can do. I am disputing charges with credit card company. so disappointing.

Two months to get it and no mention of needing a power bank. I get that it’s a kickstarter but when ordered the sight said it would be end of December possibly beginning of January. It just arrived on the last day of January more than w months later.

I was advised on January 12th my order would ship in a week and a tracking number would be sent. So far no shipment has been received, and a request for updates and a tracking number has been ignored. A review should include all facets of the buying experience. My experience has not been a good one.

Ordered from them over 8 months ago. Shirt was shipped finally without address only zip code so was returned. Polar Seal guaranteed to reship if I would let them and never received shirt or refund. VERY EXPENSIVE MISTAKE!!!!!!!
Can’t say anything about the product but the service is awful. Sure, you can say it’s a Kickstart but don’t advertise a delivery timeline and not be able to follow through as well falling down on communication. My order was intended as a Christmas gift. I placed my order the first week of December and expected delivery early January as they indicated. It wasn’t until January 11,2018 I received an email that my purchase is being dispatched and will be delivered the next week and the shipment tracking details to follow. Two weeks and more went by and no further follow up. I sent an email February 1 requesting, more like demanding a refund and to cancel my order which prompted a response with an apology and that they have dispatched my order completely ignoring my refund/cancellation request. I received another email indicating a refund will be processed within 10 days. Another email a day later that they apologize that they did not see my refund/cancellation request before dispatching my purchase. It’s an attempt to save the sale and now I am forced to wait for the receipt of the shipment and then having to ship it back before I can get a refund. They’re more than happy to take your money and not bother with follow through of completing the transaction as promised and really fall down on the ability to deal with customer issues. Or maybe that’s on purpose since they already have your money.

My husband got me and my mom this for Christmas. I wasn’t too concerned about the delay in receiving (just arrived 2/15) bc I assumed this was a Kickstarter.
No Powerbank included?!?!????
The shirt seems as though it will work great…that is if I remember to order a POWERBANK!
This is why the 2 stars. $169 and you have to buy an additional battery to get it to actually function!
The instructions do not even state that the powerbank is not included. I spent 10 min looking through the box and instructions to see if they forgot to include it…
Unfortunately, I had a bad taste in my mouth about this shirt right away because of this.
When I finally do get around to “completing” the set up of the shirt- I’ll write a review in the actual functionality. But since Spring is almost here it may be another 9 months before I actually use it

1st any good review about this product or company is a lie, I canceled the order prior to them mailing it, they sent it anyway and didn’t refund my money. Upon receiving it we tried it out, the quality of the shirt does not feel good, it feels like you are putting on 2 shirts at the same time, and the heating element only lasted for 38 minutes, they blamed the batter pack I purchased. their customer service is poor and dismissive. I have been trying to return for my refund with 5 days of receiving it, they lied and said their company does not take returns but I can mail it back for exchange, mind you to mail a shirt I paid $170 will cost 100$ to mail!! stay away from this company, they are located in Hong Kong, I am filing fraud with my bank because what they provide is sub-average quality and dosent meet expectations or what they advertise.

Heats up very quickly. Took 4 months to arrive here in Canada and there’s no battery included but still a good product.
Top took 3 months to arrive which was a little annoying but customer support was quick to respond and eager to address any concerns. Once received very happy with the quality of the product. Great color, great fit, and heating works instantly. Agree with other comments regarding reviewing the product itself not the shipping. Did some extensive research into the power bank and settled in a Jackery 12000MhA. The heating lasts an entire day out and about with this.

I would give it no stars if I could because I never received my order after over 3 months. Don’t trust this company. My credit card was charged in December and I still haven’t received it in mid March
I’m extremely happy with my POLAR SEAL top. Its been keeping me warm throughout the whole winter season. The fabric and finish quality of the product superb. What a pleasure to feel nice and cozy even out in a snowstorm. I’m now ordering some for all my family members.

Just received my Polar Seal heated base layer today. Walked through the snowy streets of London feeling nice and warm. Love this product!
Very disappointed at my POLAR SEAL experience. Firstly because it’s taken four – almost 5 – months to get my shirt delivered: I placed my order at the beginning of November, and I only got my shirt today, which doesn’t make sense as I purchased it as a Xmas gift for somebody.
Then, when I went to my local post office this morning I found out I had to pay around 70 euros for import duties!!!!, thing I would have really appreciated to be informed on beforehand, import duties being half the price of the shirt, as this has made the purchase a lot more expensive than I expected. But what matters the most, it was made deceptive and misleading by their clearly advertising ‘Free Shipping Worldwide’ in their website page, and later during the check-out and payment process!!!
Haven’t tried it on, however no positive feedback whatsover can be expected of me.

I am very happy with my top, it heats very fast and well. The shirt is very well designed and the buttons so easy to use.
Just got my Polar Seal today. Really impressed with the packaging and attention to detail. The heat is really comfortable and the fabric is great quality. Can’t wait to try it out on my ski trip to New Zealand!
I give this no stars. Got my shirt as a gift. As others stated no battery pack. After trying two different types finally got the shirt to work and loved it. After using 4 times stopped working. Sent it back and was told there was no problem with the shirt. I wanted a new one but they sent me the same one back. I am beyond annoyed. I know my daughter paid a lot of money for it. They certainly do not stand by their product

After waiting months for the jacket I was totally disappointed when it arrived. The jacket does not do an adequate job of heating. Using $1 handwarmers tucked in my shirt does a much better job of keeping me warm.
People talking smack are talking about the shipping and not the product itself. Not sure why you’d expect a product you buy on Kickstarter to arrive immediately. The zip tops are actually extremely high quality and I got mine within a week of ordering from their website…

These garments are shipped incomplete with no 10 amp USB charger. Others sold by Amazon at a lower price include the charger and will arrive in 2 days. These people have not yet learned minimal business standards.
My wife and I own a couple of these heated zip tops. We got them for cross country skiing and when we are up in altitude exploring the mountain trails. We’ve also started to use them casually on the colder days. I like how easy they are to use. The lights on the buttons are a real conversation starter. I’ve converted a few friends and climbing buddies and they all seem to enjoy the product. Thumbs up to Polar Seal.

Ordered 3 items (that the website said were IN STOCK), but only 1 item a arrived before Christmas and have just been informed the other 2 items will not arrive until February. I complained and was told the items had shipped, and then complained again and was told the remaining 2 items will not be shipped until February. VERY POOR SERVICE to take money for items you clearly do not have and can not deliver.
