    Comments about Arc'teryx Alpha SL Jacket:

    This is a 'one size fits all' hard shell. Layer with an Arc'Terex softshell and you have a complete package. I'm 6'1", 180LBS and a large fit me perfectly. Just returned from a 3 day, 25 mile backpacking trip in Colorado and it rained every single day. This thing is ULTRA LIGHT WEIGHT and great for backpacking. Sheds water like a beavers pelt.
