Arc’teryx Norvan SL Hoody $440
The Norvan SL is paper-thin, remarkably tough and is actually breathable, which is a revelation for a legitimately waterproof running jacket. It’s slim cut behaves nicely with a pack on, and the fitted hood stays up and doesn’t bounce around during a run. The Norvan SL can pack into a handheld size for easy carrying when the weather improves. Simply put, it’s the best option for serious outdoor running.
