We love an Indian summer as much as you do, but sometimes the fringe seasons aren't as ideal as you want. That's why the Micron 0's water-resistant down, rated for temperatures as low as -18°C, ensures warmth long past the vagaries of shoulder-season weather. The Micron 0 is an ideal choice for trips, climbs and treks when sub-freezing weather is imminent.
