The Flare | World's Warmest Shirt w/3X Phone Charging



What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

A Powered Shirt!? 

We're BLANC - we’re passionate about designing problem solving products that are comfortable and useful to allow more exploring than ever before. The company is named after Mont Blanc - the highest peak in western Europe.

Mount Blanc is a symbol of exploration which is home to hiking, skiing, paragliding, mountain biking, ice climbing, travel and on and on - to us Blanc is just that.

Introducing The World’s Warmest Shirt - The Flare 

What Is The World’s Warmest Shirt?

Oh boy, we were hoping you’d ask. We’ve set out to design the warmest shirt on the planet! One major challenge is how to keep warm but also to not overheat or sweat. Most of us layer up to keep warm, but then end up getting too hot. When resting or starting an activity, you’re cold, but when active, you can overheat. We thought, what if there was smart clothing that adapted to the body’s needs?

Here is the shirt that warms you when you need the heat, and doesn't overheat you! It warms you like multiple layers, but is lightweight and can be temperature adjusted to fit your needs. After many prototypes, design changes, manufacturer evaluations, performance tests, focus groups, and late nights...we’re thrilled to share the shirt that will keep you feeling just right no matter where you are headed!

Our Story

Greg & Chris here - We're two brothers that were raised high up in the Rocky Mountains and have become quite familiar with the feeling of being cold all too well. Greg wanted to figure out a way to help people stave off the cold & as an engineer Greg started working on a technical shirt & built tons of prototypes. He started nailing down a really cool product. 

Greg brings the engineering and product design expertise to the table, while Chris brings experience in successfully launching products on the Kickstarter platform. Chris has launched two successful Kickstarter products and has a lot of experience from the top-down to get a campaign prepared and to get the Kickstarter rewards into your hands.

With your help we can meet the production minimums and bring this product to life!

Wait, why is this so warm and how does it keep me so warm?

It’s equal parts dapper and technical. The feel and look of the shirt was designed to be wearable not just under your top jacket but on it's own too! It has low profile features that sneak in technology without screaming tech geek. 

Let’s start with the technical aspects of the shirt that make it so unique.

Moisture is wicked out, heat is generated by middle layer and retained in.
Moisture is wicked out, heat is generated by middle layer and retained in.

We’ve integrated a patented & lightweight battery powered carbon fiber heating technology throughout the shirt to keep your body warm for when and where you need it most. These heating elements use a carbon fiber technology that quickly heats up and efficiently draws minimal power. The carbon fibers are also non corrosive for a long lasting build that has been time tested so the shirt is durable + can be fully washed.

Carbon fibers are the most durable & flexible heating fibers that can be packed tightly into tight travel bags.

The shirt's power button is on the lower side, out of the way to avoid getting bumped and where it can be easily seen or felt to turn on.

How does it feel?

How does it work?

Three Warmth Settings

From lounging, traveling, or playing outside in nippy temperatures there’s a warmth setting that will fit just right. Keep your body warm in vital locations on your body at the right temperature with the touch of a button.

There are three different warmth modes that can be used as a thermostat to cycle through the temperature that fits your needs. 

Switch between settings at the switch of a button.
Switch between settings at the switch of a button.

Low Warmth Setting

Set the colored LED button to white and get hours of long lasting/steady warmth. Perfect for when you need a little extra warmth in a drafty movie theater, on an airplane, or at work.

Medium Warmth Setting

Click the colored LED button to advance to orange for the next warmth setting for an extra warmth boost. This setting is great for getting out the door on those early mornings with that crisp autumn air, at those chilly sporting events that go into double overtime, when you warm up for a run.

High Warmth Setting

Oh Baby, it’s cold outside. The third heat setting is for when you really need furnace-like heat to curb the cold. This is what our ancestors dreamed about. Stay merry while on that family trip chopping down that perfect Christmas tree in the middle of the forest. Wear it under your jacket to keep toasty while on the ski slopes.

The Included Power Bank

The shirt comes with a strong 6000mAh power bank that packs a punch with a run time powering the shirt of up to 5 hours.

The battery pack is lightweight and is about the size of an iPhone 6. The battery stores in the side pocket with room to spare. You won't feel the battery tugging the shirt down.

Using the standard USB connection you can also use larger power bank to power the shirt by placing it in the shirt pocket, in your pocket, or in a pack using the extra long USB cable.   

Larger battery packs can be used and held in a backpack.

The power bank can also be used to charge your devices when not heating the shirt - perfect for when a device like your phone needs a boost.

Easy To Wash

The entire shirt is washable! (yes...the circuits can handle it!) We have extensively tested the shirt in harsh conditions and through many cycles to verify long term use. Just remove the battery pack and throw your shirt in the wash for your next event or trip. It is best to air dry to keep the shirt lasting as long as possible.

When will it all ship?

March, 2019

This timeline has been created by factoring the absolute longest time estimations for each stage. We are going to work to try and stay on the earlier side of the estimations to get these shirts into your hands but we are trying to be as realistic as possible :D


All of the features were optimized and tested to ensure use and high quality for a shirt that will keep surprising you with it's versatility. If for any reason there is a manufacturer defect, we will replace the shirt within 1 year of your receiving of it. The warranty applies to both the shirt and the battery pack. 

Return Policy

We only used premium products and offer a 1 year warranty. We will repair or replace any shirts and battery packs that would have manufacturer defects or don’t hold up under normal use. We do not offer refunds on shirts that were received as a Kickstarter reward.

We’re passionate about creating amazing products and Kickstarter is a way for us to launch our brand. As you've read, Kickstarter isn't a store and rewards are a thanks for supporting the project which is why we cannot offer refunds or returns. Your pledge means so much and we take it very seriously. We will do anything we can to make sure that this exchange leaves with good vibes for everyone involved.

Risks and challenges

As you backers know, there are always risks with new products. The production line could have a slower throughput than expected or materials could he held up. Our manufacturer has been carefully selected and the due diligence has been performed to make sure they have excess capacity to bring the product to the masses. Each aspect of the project has been considered when setting up the manufacturing line such as the following;

-Quality: 5 in-line quality inspections, product tested to ensure meets standards of durability and use, only premium materials and components used in product, certificates of compliance ensures that each shirt and battery meets our high standards.

-Manufacturing: manufacturer capacity is orders of magnitude higher than out need, dozens of manufacturing sites mitigates labor problems or even natural disasters, We have agreements in place with the manufacturer to ensure that product is delivered on time and that no intellectual property is lost. US distribution allows control with our experienced order fulfillment group.

-Legal: The patented heating technology is protected from duplication and the proper international standards are being followed with the handling of the battery and shirt.

As with any new project, there are always unknowns. We have done due diligence in all aspects of the project to mitigate risks. If there are any issues with the delivering of the product to backers, you will be the first to know and we will take corrective action immediately.
