Pretty good for the $200 I spent, really good at the sale price. I’d say around 80% more fill than the kuiu ultra, quieter material. Mine have a somewhat sloppy stitching but hasn’t come apart. A large weighs a pound.
Traceable down, mine actually tested at 840fp grey goose down and 93% down 7% feathers. Maybe not the tip top quality but pretty close.
While it’s quiet I wish the face fabric was more water resistant like what Sitka uses on their kelvin lite pants. Zipper is short and so is the rise.
Honestly I think they are overkill if going to just ride in your pack. Better suited for winter or long sits.
