Best for wet, active adventures, the Guardian II AscentShell Jacket kicks your expectations about breathable waterproof jackets up a notch. Feature-packed and performance-driven, the Guardian gives you every ounce of protection you demand, with the details you need to keep hiking in inclement weather. This season, we've upgraded the Guardian's pit zips to TorsoFlo™ Hem-to-Pit venting, and added a reflective hit for visibility on a dreary commute.
Since 2016, Outdoor Research's proprietary AscentShell™ technology uses an electrospun process to create a 3L construction that breathes faster, weighs less, stretches more, and far surpasses the comfort of traditional waterproof membranes.
