Anthracite 20°

I've used this bag on three trips now, and the mummy cut keeps me tucked in tight without feeling claustrophobic. The recycled synthetic insulation dried out fast after a surprise drizzle, and I stayed warm right down to the low 20s.

Woke up at 4 a.m. in the high desert with frost on the tent fly, but the synthetic fill kept me warm enough that I actually unzipped the mummy hood before sunrise. The recycled insulation packs down smaller than I expected for a 20-degree bag, which made the hike to camp a lot easier.

Drafted a lot of rainy nights in the Sierra and the mummy hood still cinches down tight enough to block out the cold draft entirely. The recycled synthetic fill has kept its loft through three trips so far, which is more than I can say for my old down bag. Slept like a rock at a frosty 25°F.
