I've never owned the Day One wool but I have a good bit of their regular camo. I also have an N.A.O. (North American Outfitters) coat that was the original name of the company I believe. I think it ran NAO, Hidden Wolf, something else and now I guess Gray Wolf??? Maybe I'm not thinking of the same company. I think the wolf skins company is NOT the same company line I'm thinking of but I'm not certain. Too many companies with "wolf something or other" in the name for me to keep them straight.... I do remember NAO was owned by a guy named Marc Barger back when I got mine. I'm pretty sure it's changed hands multiple times so I'm sure there have been changes made to the whole line.
Honestly, I didn't ever care for the DESIGN of the coat. Pretty much zero flap overlap over the zipper, tight in the arms, poor pocket layout, didn't like the collar style, the detatchable hood was so short that when I had it up, the entire weight of the coat rested on top of my head and oh, I'm sure there were other things. It's been laying in a plastic tub in the basement for years. Last I'd looked at it, a mouse had chewed a hole in it by the bottom edge...
Anyway, long story short, I've always been happy with anything I bought from Day One and would shop there again. The Wolf something or other place, I'd prefer to try before I'd buy. Might be great stuff nowadays????
