The Arc’teryx alpha jacket Is a full protection shell jacket that provides shelter from storms, rain, snow and can withstand the challenges of everyday use. Revised technical construction of the Alpha Jacket has produced a lighter jacket that uses less tape and stitching, which in turn increases overall breathability. MN70p-X GORE-TEX® fabric is the hardest wearing windproof, waterproof/breathable protection available. The length of the jacket covers all mid layers; dropped back hem protects the lower back.
And this is on my buy list.
