Celsius XXL 0°F

First winter camping trip with this bag and I actually stayed warm through a 20°F night, which never happens for me. The oversized cut meant I could wear a thick base layer and still roll around without feeling stuffed in, and the zipper never snagged once.

I usually sleep cold even in summer, so I was nervous about a 0°F bag — but this thing is a furnace. The oversized cut means I can wear my thickest socks and still roll over without fighting the fabric, and it kept me toasty on a genuinely frosty night.

Took this out when the forecast said 15°F and I stayed toasty all night — the oversized cut actually lets you move around without letting cold air in. Roomier than any sleeping bag I've owned, and the extra warmth is exactly what I needed for shoulder-season trips.
