Put Your USB Battery Packs to Use This Winter With a Heated Base Layer

Warmth on demand isn’t just science fiction anymore. Polar Seal clothes give you the ability to add even more warmth to your winter layers with built-in warming elements, powered by any standard USB battery pack. The two heating zones and three heating levels are controlled by the waterproof buttons on your wrist. Preorder it now through Kickstarter and automatically save $30, or grab a two-pack and save $69 (nice).

Our office is freezing and I tried this guy out for the day and it was really great. Even with the battery pack at my hip, it didn’t feel like any extra weight, which was something I was worried about. With a 5,000 mAh battery, it’ll get you around four hours of heat, and a 10,000 mAh battery will bump it up to eight.
