Iron Heart

21oz IH-555-03 Super Slim Jean Superblack Fades To Grey


NOTE: Sizing has been slightly adjusted, please reference size rec. and chart for updated measurements.

The IH-555 Superblack Fades to Grey denim is arguably the greatest fading black denim in the world.  Think beautifully worn-in faded blue jeans but in grey tone.  Iron Heart's 21oz denim is no joke--heavy but unexpectedly soft and breathable, feeling deceptively like a mid-weight jean when worn.  Model is 5’10,” 175 lbs wearing size 30. 


-Made of 21oz "Superblack Fades to Grey" (SBG) sanforized Japanese selvedge denim

-Black sulphur rope dyed warp & black reactive dyed weft 

-Super slim 555 cut with medium/ high rise and slim/ tapered leg 

-Lined back pockets, button fly, hidden rivets, belt loops sewn into waistband

-Selvedge side seams and fly construction


Black sulphur rope dyed warp/ black reactive dyed weft.  With time, the warp will fade but weft will not.
