The Mammut Waymarker IN Jacket packs 700 fill power down, insulation that's fully recycled along with the wind- and water-repellent Pertex Quantum shell. A chinguard and a storm flap behind the front zipper hold up against wind and moisture on cold days without adding bulk. We reach for this jacket on hikes, travel days, and everyday errands alike, since the recycled build keeps the same warmth and weather protection as a standard down piece. What Our Gearhead(R) Experts Are Saying:"I wore this through a wind-whipped trailhead parking lot and never felt a draft sneak past the chinguard. It packed down small enough to stuff in my carry-on the same week, so it never left the rotation."
