Used at -18°F and stayed warm
Camped in the backcountry in late January. Slept comfortably all night. The hood and draft collar really work — no cold spots at all.

Down quality is exceptional

Compression sack works well
Compressed bag packs down smaller than expected. Compression straps are easy to use. Good size for fitting in a backpack.
