There’s only 2 companies that make good 2in1 shorts, asics and zoot. Asics have lost a bit of my confidence as their compression liner is made with a material that seems a bit weaker and thinner than previous years but they still work well. The zoot ultra shorts are really good. The best are the shorts with thigh long compression liners and has a large zipper pocket on the butt. There is also a shorter version with a bikini brief liner, but I don’t like them for long runs (over 8 miles). Great for 10k races though!
If all that fails, under armor makes a runners square brief. It’s awesome!!
Saucony 2-1 is a good option too.
