Lumina 100 Down Jacket Women's

Pulling this jacket out of my pack mid-climb felt like cheating—170g and it cut the wind completely. The 1,000 cuin down is noticeably warmer than any other lightweight layer I've used.

I was shocked at how warm this jacket stays given it weighs next to nothing — perfect for alpine starts when every gram matters. The 1,000 fill power down traps heat without the bulk, and it packs down smaller than my water bottle.

The 70 grams of Italian down in this thing is sorcery — it's warmer than my old jacket that weighed twice as much, and it packs down to basically nothing in my backpack. I've worn it over a fleece on chilly mornings and it's all I needed.
