I have a pair of Tellason jeans made with Blue Pine selvedge denim from their now defunct North Carolina loom. Found them at a consignment shop for $20. Sold for $250 originally.You want jeans with cotton done on an old fashioned shuttle loom.
The high dollar "1947", retro.. special edition jeans are often such jeans.
The cheapest with such construction are $88. This company sells varying weights.

I quit wearing jeans for the most part because I lost weight and what I have is too large. Was a 32X34 with a belt.
After getting some track pants, it will be very hard for me to go back to stiff old jeans.
