Calling your product the “warmest jacket on the planet” is a pretty ballsy claim. But, the LifeLabs MegaWarm jacket has been bestowed such a title thanks to the highest CLO rating of any jacket in existence. Made with 100% recycled polyester in both the body and lining of the jacket and filled with an insulation of ethically-sourced goose down, this jacket promises excellent performance in brutal conditions. By using the brand’s proprietary WarmLife technology, you wind up with an extremely impressive jacket that’s warm and breathable. Plus, it’s sustainably made, extremely light to wear, and comfortable. As you gear up for cold temperatures, the MegaWarm winter jacket will provide next-level warmth.
