2 in 1 running shorts pair an outer short with a built-in compression liner in one garment, combining freedom of movement with underlying support.
Most running shorts have a built-in liner or brief, so you don't need extra underwear underneath. Unlined shorts can be worn with moisture-wicking underwear if you prefer more support.
The best running shorts fit your distance and training style: lightweight shorts for speed sessions, 2 in 1 shorts for long runs, and longer styles for everyday mileage in cooler weather.
Compression shorts can improve muscle support and reduce fatigue on long runs, and many runners find they help recovery between sessions. The liner in 2 in 1 running shorts gives some of this benefit without full compression tights.
Liners in running shorts reduce chafing between the thighs and add light support, working like built-in underwear so you don't need a separate layer.
5-inch shorts suit faster running and hot weather thanks to less fabric and more airflow. 7-inch shorts give more coverage and comfort for longer, steadier training runs.
