The ST95 Acidita Sweatpant draws inspiration from Massimo Osti's pioneering Lab philosophy, where experimentation and garment treatment became central to the creative process. Crafted from a substantial 490 GSM 100% organic cotton loopback jersey, the sweatpants are garment dyed before undergoing a bespoke acid wash, creating a distinctive balance of faded highs and rich tonal depth that evolves across the garment. A garment-dyed archival ST95 Lab patch references the brand's research-led heritage, while slanted stash pockets at the hips and a rear right-hand pocket provide everyday functionality. Finished with an adjustable drawcord waistband and a relaxed fit, the Acidita Sweatpant delivers comfort through considered design.
