Montane Slipstream GL Smock - Men's Medium

This thing is a crazy light windshirt at 2.9oz. and it blocks wind like a boss. Only worn 3 or 4 times, just looking to thin out some of my gear. Can't find any of these online for sale, but they used to retail for $159.

Asking $50 shipped CONUS For pics: https://imgur.com/a/bagWd For size reference, I’m 5’10” 175lbs. and the pics show I can wear it with a light fleece with room at the waist and great arm articulation.
