13 Running Hats That Are Super Lightweight, Comfortable, and Functional

Adidas Terrex HEAT.RDY Five-Panel Graphic Cap ($30)

This Adidas running hat from the brand's outdoor-focused sub-brand, Terrex, is made from recycled materials and perfect for taking into the woods. The HEAT.RDY technology manages heat to keep you running, hiking, and exploring in hot weather, and an inner sweatband helps capture any sweat that does arise. If it gets dirty while you're tearing up the trails, just toss it into the washing machine.

Why we love it: Reviewers call this cap "superb" and say it's great for workouts of any type. "Great hat for runs, looks good, comfortable and great breathability," one customer writes.

What's worth noting: A reviewer noted, "Good cap. Great for exercise. Feels a bit flimsy. Breathable and light. Bit floppy at points."
