Best Breathable Running Shorts Men in 2026: Our Expert Pick After Deep Research

My brother-in-law, who did a stint in the military, has been talking about ‘Ranger panties’ for running since basically the day I met him, and I finally understood why after one humid summer training run in my regular shorts left me feeling like I'd run through a swamp. He walked me through why the old-school PT short design actually works — barely any fabric, zero drag, nothing to trap heat — and I was skeptical it would look normal on a regular guy at the local track. I compared a couple options based on his description before landing on the actual Soffe pair he swears by, since apparently the knockoffs don't hold up the same way in the wash. Wearing them on my next few humid runs, I finally got what he meant about the heat — there's just nothing there to overheat in. They're not going to win any fashion awards, but for pure breathability in brutal summer humidity, nothing else I've tried comes close. He still brings it up like he invented them.
