Altamont Picos: Really tight fit, not enough stretch.
I have a pair of the Picos, and unlike the other Altamont pants I've had in the past, these pants do not stretch at all in the slightest. And for how tight they are, it's quite problematic. They're EXTREMELY stiff, so forget about trying to skate in them. And overall they're just not very comfortable. They're just a very constricting pair of jeans, and this is coming from a guy who owns Corey Duffel's signature jeans.
The one positive thing I can say about them is if you're looking for a jean with an extremely tight fit they do fit the title. I could see them being a decent pair of jeans getting them a size bigger, or I almost dare to say two sizes.
