When the now-classic Arc'teryx Alpha SV Jacket debuted in 1998, it blew people's minds. Originally designed as a foul weather fortress for year-round alpinism, the jacket proved so durable and functional that people reasoned it would make a great ski coat as well. They were right. Over the years Arc'teryx has made improvements to the Alpha SV, including the welcome adoption of its highly breathable GORE-TEX® Pro membrane, but it still sits atop the pile in the bomber hardshell jacket category. If you spend a lot of time in the mountains and are used to taking a bit of weather in stride to meet your objectives, consider the Alpha SV an investment you won't regret.
