The name says it all. This shell protected our testers from hail, rain, and eyelid-fluttering winds year-round in the Colorado high country. And at a whispery 11 oz., it’s stealth and compact enough to disappear into a pack and not be a weight liability. Details are climber-approved: The hem is long and harness-friendly; double sliders on the front zip allow for opening in either direction (key for belaying); and broad elastic wrist closures work well with gloves while a generous chest pocket houses a bar or walkie. Bonus: A slick magnetic closure keeps the storm flap sealed up tight.
