While fashion brands often design their garments based on fleeting trends, twin brothers and athletes Nick and Steve Tidball create items for their menswear line, Vollebak, with a more certain future in mind: one that involves environmental threats and the continued exploration of space, and that may very well demand more from our clothing. Their participation in extreme sports—the pair has sprinted for hours across Africa’s Namib desert in 130-degree heat, completed a weeklong ultramarathon through the Amazon jungle, and run a 120-mile race over the Alps—regularly informs Vollebak’s designs, which take a markedly long view on clothes. Made using some of the most durable and cutting-edge materials on earth, its groundbreaking pieces are virtually indestructible, yet appear as pared-down essentials. All are created to protect and aid wearers as they make their way through the world’s ever-changing terrain.
