Inspired by the latest innovations in fabric technology the Alpha Flash radically reinvents the traditional mid-layer.
Love it! The breathability is impressive and allows for an awesome range. I have substituted it for an Ortovox wool sweater under a light Ortovox jacket in my morning straight up the ski mountain skinning setup here in Steamboat and haven't needed to unzip even up to 31 degrees this morning. Before I was unzipping in the 15 degree range.
