Our best-selling boxer shorts redesigned for increased breathability during high-output activities, the all-new Anatomica Zone Boxers feature the same incredible fit and comfort with added ventilation. These lightweight, stretchy and incredibly breathable boxers feature our jersey Cool-Lite(TM) fabric, which features corespun fibers-nylon threads wrapped in merino wool for the ultimate combination of next-to-skin softness and durability. In addition to this naturally breathable fabric, we added panels of corespun eyelet mesh in key areas to provide maximum airflow during active pursuits. The gusseted design aids in range of motion, while flatlock seams throughout provides chafe-free comfort no matter what the day has in store.
