Kathmandu has partnered with Archroma, the global color and specialty chemicals company, on a capsule collection of signature hoodies. The collaboration sees Kathmandu use Archroma's patented EarthColors range of plant-based dyes, which are said to be sourced from up to 100 percent renewable resources. Colors are synthesized from plants as opposed to the oil-based raw materials conventionally used in dyes production. Before Kathmandu, Patagonia announced in May it would use EarthColors in its Clean Color Collection. In June of this year, Archroma's EarthColors dyestuff range won the Gold Winner award at the OutDoor Industry Award 2017 in the “sustainable innovations” category. EarthColors dyes are sourced from renewable resources including the natural waste products of herbal extraction and agriculture. The colors are available in a range of six dyes that change and fade over time. Kathmandu's so-called “vintage casual” collection features Archroma's dyes including burlwood rose, burnt olive and slate blue, which are derived from non-edible parts of almond shells, other nut shells, bitter orange and beetroot, rosemary and saw palmetto.
