Evelyn ★★★★★ Aug 13, 2026

Took this out on a frosty morning hike and stayed warm with just a base layer underneath—the 850 fill down is no joke. It's ridiculously light in the pack, which I barely noticed until I needed it.

Ruby ★★★★★ Aug 12, 2026

Packed it down to about the size of a loaf of bread and it bounced back to full loft in under a minute. The 850 fill down is seriously warm for how little it weighs, and the golden yellow makes it easy to spot in a messy tent.

Took this on a week of mountain trips and was shocked how small it packs down for a 400-fill jacket. The 850 cuin down is noticeably warmer than my old synthetic, and at this weight I barely feel it in my pack. The golden yellow shade is a nice bonus for visibility on the trail.
