For those of you who love a heavy selvedge denim, you must check out Iron Heart. For their 5th year Anniversary celebration, they are coming with a special IH-634SR jean. Say sources at Self Edge, it will actually feature unsanforized 22oz denim and once washed, it bulks up to 24oz, making it the world’s heaviest denim right now. This extremely rigid denim will be released in late May with only 500 pairs available at Iron Heart UK and Self Edge.
