MicroTherm™ Down

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.

StormRepel®

Our durable water-repellent (DWR) finish causes moisture to bead up on the surface so it rolls off or evaporates rather than soaking into the fabric.

"The MicroTherm™ vest is perfect for year-round insulation. It is light enough to take anywhere, durable enough to wear all year, and stylish enough to wear everywhere."
