"Men's Brooks® Dash 1/4-Zip 3.0: The Brooks Dash 1/4-Zip 3.0 is a men's long sleeve running top built for those in-between days when the weather can't make up its mind. Whether you're heading out for an early morning run or layering up before a tempo workout, this semi-fitted quarter-zip gives you the flexibility to adjust on the fly - literally. The 1/4 zip lets you vent when you warm up, and thumbholes keep your sleeves in place when the chill returns.The GO2™ fabric is 88% recycled polyester and 12% spandex, which means it stretches with your movement, wicks sweat efficiently, and carries a UPF 50+ rating for sun protection on longer efforts. The recycled polyester construction reduces environmental impact without compromising on feel - the fabric stays soft against skin through the whole run. Reflective branding adds low-light visibility, and the watch window on the left sleeve means you can check your pace without fumbling with your cuff. It's a practical detail that makes a real difference mid-run.Why Our Fit Experts Love It""I grabbed the Dash 1/4-Zip 3.0 for a morning run when I wasn't sure if I'd need a layer or not - ended up being glad I had it. The watch window is something I didn't know I needed until I used it. No more pushing up the sleeve to check my splits. The stretch is great too, nothing bunches or pulls when you're moving."" - Dave, Road Runner Sports Fit Expert, San Diego, CAWho It's Best ForThis top is a strong pick for men who run in variable conditions and want a lightweight long sleeve layer that handles both cool starts and warmer miles.
