Voltaic Heated Jacket

Nylon-spandex, which is the part that makes a heated jacket wearable.

Most heated outerwear is stiff — the wiring and the shell fight every movement. The Voltaic uses a shell with stretch in it, so the jacket still bends at the elbow and shoulder with the heating elements in place. That's the difference between something you wear on a job site and something you wear once.

Four colors — black, blue, red, and army green — and a size run to 5XL. The heat runs off a USB battery pack, which slips out before the jacket gets cleaned.
