Giles wrote this in November to explain the relationship between IH and TW:
Works Inc, which is effectively Haraki, owns 3 brand names. Iron Heart, Triple Works and FreeBee. Iron Heart is reserved for the super heavy/ultra tough stuff. Triple Works to date has been the brand that he sells lighter weight (normal to most jeans companies) garments. When I did my 13.5 oz collab (TWHR01), we branded it TW as it was a lighter weight and did not fit in with the rest of the IH portfolio. Having said that, Haraki designed the jeans with my input, and they are made with exactly the same attention to detail and signature touches that all Iron Heart jeans are made with.
Recently, Haraki licensed the name triple Works to a mate of his, this guy who owns TSS, the company that supplies Works with all their denim. Haraki does all of the design work, TSS supply the denim and are marketing the new Triple Works to a wider more mainstream audience than IH. The detailing is still second to none, the denim is still awesome, but in the main is a little more fashion orientated. And I have to say the Natural indigo, 100% organic cotton mens jeans in the new range are fantastic and extremely well priced for a natural indigo denim. What makes them special is that the denim is actaully rope dyed which is extremely rare for a natural denim.
