The Zenith series down-filled sleeping bags are designed and built for high-performance. The Zenith is constructed using a durable, polyester ripstop shell with soft polyester liner and RDS certified 600-fill hydrophobic down.

Warm & dry in a bad snow storm

I used this bag for a high elevation Colorado elk hunt in late October 2019. On our second night we got hit by 18 inches of snow and temps in the teens with bad condensation raining down on us from the tent ceiling. I just burrowed into my bag and stayed warm and dry, even though the outside of the bag got soaked. Paired with Alps Outback Mat- super comfortable and warm.

Warm and Cozy

Used the long for past 2 winter camping outings. 7,12,multiple 20 degree nights stayed dry and toasty. Not the lightest 0 degree down bag, but extremely comfortable and packs down well.

Side sleeper, Use R 4.5 pad with this bag. No issues with zippers so far. Great value. No pad straps
