The Nike ACG Lava Loops Trail Running Tights are hands down my favorite running tights. The combination of comfort, breathability, storage, and durability is tough to beat. The pockets are incredibly functional and hold everything I need without bouncing or feeling bulky, which is a huge win during long training runs and races. Most importantly, they don't chafe. When you're spending hours—or days—on the trail, that matters more than almost anything. The fabric breathes well, moves with you, and stays comfortable even when conditions get tough. In fact, I trusted these enough to wear them for the entire Cocodona 250, and that's about as strong of an endorsement as I can give. If a piece of gear can survive 250 miles of running and still earn a spot in my race kit, it's doing something right.

Amazing pair of tights. Lots of pockets for gels. The back packet was large enough to fit an iphone 17. And no chaffing at all. My go to tights for race day.
