Lawn season is a 90-day sprint. The Grass Mastah Lawnmower t-shirt is for the dad who’s already got the mower out by 7am every Saturday from May through September, who’s got the perfect line pattern figured out, and who’d argue that a freshly-cut yard is worth more than the property assessment says. Bold “Grass Mastah” lettering, retro lawnmower graphic, and a soft cotton blend that breathes through July humidity.
Light enough for sweaty afternoons, soft enough for the cookout after. He’ll wear it on lawn-day Saturdays, weekday evening mow-and-edge sessions, and any time the temperature climbs.
