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:

These photos and videos provide a detailed look at this project’s development.

Check your temperature right now.

Chances are, you are either in an air conditioned office or cozy up in front of a heater (or fireplace) at home. But we are not always in our comfort zones, how about the times when we are doing outdoor activities or even in crowded places? Why should you care? It affects your health, see below for what happens when you temperature is out of balance:

Still don’t care?

What if you can enjoy your personal comfort temperature and also look stylish and stay conveniently connected to your smartphone at the same time? With N2, it is a reality.

And did you know...

According to surveys, the average home-owner spends over $300 per month on cooling and heating their home. The air conditioner on the left will consume about 2,352 k Wh per year. The one on the right, with the G2T will only use 6 k Wh per year, at the same time, staying comfortably and saving money (and the environment).

Re-define personal comfort and convenience

N2, the world’s first complete temperature controlling wearable that keeps you connected:

What does it mean to be connected?

N2 is Bluetooth 4.0+ compatible which means is easily paired with any iOS or Android device.

Once connected, the user can enjoy the following:

hands free phone calls

stream live music, radio, and podcast

speaker source for watching your favorite YouTube videos

GPS access directions while riding your bike

Works perfect with some of your favorite online music services:

N2, the perfect healthy lifestyle solution.

Not only does N2 regulate your body temperature so that you stay healthy, but it also encourage safer listening habit.

According to the U.S Department of Health, approximately 26 million Americans between ages of 20-69, have suffered permanent noise-induced hearing loss from extended use of headphones and earbuds. N2 is designed to protect your eardrums and prevent further damage while personally enjoying your music.

Let's see some test results.

So how does the N2 intend to keep you warm for the upcoming cold winter? And at the same time keep you cool in the current extended hot summer. Check out some testing results (using FLIR ONE):
