For those who know the grind never stops—just shifts sideways. The More Sidehill tee in dark heather grey keeps it simple, bold, and unapologetically MTNTOUGH. Big black letters up front say it all: More Sidehill. Because sometimes the best path isn’t straight—it’s steep, uneven, and guaranteed to burn the legs. The back features our classic MTNTOUGH logo centered high between the shoulders, a subtle reminder that toughness isn’t found on flat ground. Soft, durable, and ready for the incline—this shirt was made for those who thrive where others slide.
