Amazing quality
I was not expecting this bag to be this high quality!! After freezing my buns off in my 30 degree bag, I bought this one for a recent trip where it was about 35 degrees at night and I was SO WARM!!! It’s really lightweight for how fluffy and warm it is. The quality of the material is really really nice for the money. The only thing that I would change would be to have a waterproof toe box at the bottom of the bag. Other than that, it’s perfect.

Cold temp down bag at reasonable price
First let’s start with price point. Most 0 degree down bags cost hundreds of dollars upwards into the 300-400 dollar range where the Paria 0 degree bag does not. The zipper glides well which is nice and a huge irritation when it gets constantly caught on the bag. The down fills out after unpacking fairly quickly and provides good warm. I haven’t had a chance to test it in temperatures in the 20s so I’m not sure of its performance in cooler California mountain temps. In temps in the 40s I got hot so the warmth I feel is sufficient for colder temps. The bag stuffs down in the stuff sack easily and creates a compact bag. I’ve owned it for less than a month so cannot comment on its durability.
