I don't normally wear assos gear, but this is an exception. It is far and away the warmest base layer I've ever used, and it breaths well too. I was skeptical about using a synthetic material over merino wool but this too changed my mind. Perfect to pair with a jacket or midlayer and shell for a cold winter ride. This is what I grab for temps below 40 degrees on the bike or for a run.
Quite simply one of the most durable articles of cold weather gear for any activity. Very large temperature range of comfort, excellent wicking and never ever feels cold or damp.
