Running underwear

Do any of you use running underwear at all?

I wear compression shorts and tights when I run. I usually go commando under them because they have built-in liners or panels.

Some people prefer underwear and there are many running underwear brands out there.

Are you one of these and if so, what brand do you go with and why?

Yes,I used my underwear it's always my compression shorts as they help me prevent chafing in the inner thighs. It is a lot great with cooler conditions as it reduced muscle fatigue for me as well.

I wear half tights/compression shorts or tights as my main layer for running. Some have inner liners.

I wore Janji half tights with an inner liner for my 50K and stayed very comfortable the whole time.
