MicroTherm™ is First Ascent's lightest, warmest down construction, which pairs high quality 800 fill with some of the narrowest channel baffling in the outdoor industry. The narrow-channel construction prevents down migration and keeps the fill more evenly distributed throughout the garment—minimizing the cold spots and filling voids that could allow body heat to escape. This elevates the overall thermal value of MicroTherm™ to an extremely high degree, meaning more warmth for the same weight, reducing overall bulk and allowing for easier layering as well as greater packability. We like to emphasize it's the warmest, lightest down we've ever made.

BC MicroTherm™ Down JacketDue to overwhelming popularity and customer response, we have refined our alpine guide team's favorite piece for Fall 2012! We’ve built a warm, insulated jacket that is lighter than most non-insulated shells on the market. This jacket is built to be the minimalist, lightweight piece that our First Ascent guide team requires in the most challenging environments where every ounce counts.Eddie Bauer - EST. 19204.033299922943115
