We use US Navy Seal technology in our Climate 2 jacket through the inclusion of Polartec® Alpha®. It's an active insulation layer that is ultra-thin, lightweight, quick-drying, highly breathable, stretchy, water-repellent, packable and extremely warm, all at the same time. The close-fitting mid layer is the perfect complement to your cold weather riding gear. That said, it can also be worn as a separate jacket on its own. Though we've created it with purpose in mind – to keep you warm when temperatures start to dip! – we developed it with style too, so it looks great as a standalone piece.
