Denim feels thin but soft
Size: 32W x 32L, Color: All My Days Selvedge
The denim seems thinner than from years ago. 100% cotton feels soft. Fit me same as other stretchy 505 that are made with elastine. Waist size is fine. Haven't washed them yet. Yes, the price is high, but I like the 100% cotton and will likely buy more selvedge jeans.

100 cotton
Size: 33W x 32L, Color: Midnight Selvedge
These are great, just keep in mind that 100% cotton is not the same as 99 cotton 1 elastane, so size up if you tend to be in between mesures at waist.
