The Arc'teryx Alpha FL Jacket is the bee's knees in the world of waterproof-breathable shells due to its use of Gore's new Active Shell. Say hello to your new best friend.
That zip I mentioned earlier, it's burly enough for the Bugaboos, but light enough for those ultra-marathoner's who want an ultralight emergency shell. No embroidery here, just a laminate to save weight where weight can be saved.
The Active shell Gore-Tex makes this one of the most waterproof-breathable shells in Arc'teryx's lineup. Welcome it into your home, don't be shy.
