It lives up to its reputation - Arc'teryx Alpha FL Jacket - Men's

Major gear reviewers all give this thing the top spot for alpine hardshells, it lives up to that. Its just a slightly heavier weather proofing than my OR interstellar that it layers perfectly with an R1 in less than ideal conditions. Its sized to wear an a puffy underneath or over depending on conditions. The cuffs are better than my interstellar as well as having a wholly velcro closure instead of velcro and elastic. the downsides are cost. If you can afford it, this thing isnt hype its really almost perfect.Works great as ski jacket for bluebird days as well.
