Top Lightweight Running Jackets for Summer: Breathable, Bright & Built to Move

When the temperatures rise, every runner needs a jacket that feels barely there but still delivers on performance. The right lightweight running jacket helps you stay cool, dry, and visible, so you can focus on the miles ahead.

Below, discover our top picks for summer running gear that balance comfort, style, and protection.

Why a Lightweight Jacket Matters

Even in warm weather, a running jacket has plenty to offer. Breathable materials wick away sweat and allow heat to escape, while a water-resistant finish keeps light rain from spoiling your run. Reflective details and bright colours mean you’ll stay visible on early morning or dusk routes. And when the sun comes out in full force, a packable design lets you stash it easily in your pocket or belt.
