I was wearing this while trail running and took a spill over a root, and slid a few feet down the trail. Nothing but a few mud streaks on the fleece, no abrasions, tears or marks. Very incredible. I've purchased quite a few items from the first ascent line - in general, the tall sizes and reasonable prices gives Eddie Bauer an advantage over most other active and outdoor clothing. The quality, particularly on the fleeces is on par or above any other you'll find.
