21oz Non-Fade Denim Straight Cut Jeans - Superblack

Our classic straight cut jean made from super-heavy 21oz non-selvedge superblack denim. This denim is specially created not to fade - if you like black denim, this is about as good as it gets.

  • Made in Japan - our classic straight cut
  • 21oz superblack Japanese denim - both the warp and the weft are reactive dyed, so there will be virtually no fading
  • Zipper fly
  • Non selvedge
  • Sanforized and one-washed so no shrinkage to be expected (with reasonably careful washing and drying)
  • The waist will stretch out approximately one inch with wear
  • All other dimensions that are put under pressure will have a tendency to stretch proportionately to the stretch in the waist
  • Poly/cotton constructional stitching
  • Model Sam wears tag 32, Giles wears tag 34
  • Need a shorter length? You will be prompted on checkout to order hemming if required
