Wore this on a windy 30-degree hike and stayed toasty the whole time. The 850 fill down packs down tiny in my bag but lofts right back up. Pertex shell shrugs off light drizzle too.

I've worn this jacket through a few freezing mornings and the 850 fill down keeps me warm without any bulk, plus the Pertex fabric sheds light rain like nothing. The sleeves are long enough to cover my wrists when I reach for things, which is rare for women's outdoor gear.

Amelia D. ★★★★☆ Sep 11, 2026

The 850 fill down is seriously warm for how thin it packs down, and the diamond quilting keeps it from looking like a plain puffy. Only gripe is the Pertex shell feels a bit crinkly when I move, but it blocks wind well enough that I don't really care.
