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

I borrowed a pair of running shorts from a friend at the gym once because mine were somewhere in the laundry pile, and I remember being weirdly obsessed with how cool the fabric felt against my skin during a brutal summer cardio session. He called it ‘ice silk’ like that explained everything, and I spent way too long afterward trying to figure out what that actually meant and where to get a pair. I compared a few loose-fitting options online before landing on this one, mostly because the reviews kept mentioning the same cooling sensation my friend described. Wearing them on my next few outdoor runs, the temperature difference was noticeable almost immediately — less clinging, less overheating around the waistband. I've since bought a second pair for hot yoga days since the loose cut doesn't restrict movement. My friend still hasn't gotten his pair back, honestly.
