The Right Apparel for Hot Weather Runs

Hot, sticky miles are a summer staple—but suffering through them doesn’t have to be. What you wear can make or break your run, and the best apparel works with the heat, not against it. Think coverage without cling, featherlight fabrics, and smart ventilation. From ultra-breathable tanks to chafe-free shorts and sweat-wicking socks, ASICS has summer running essentials that are ready to work as hard as you do.

Air out up top

When every run feels like a sauna session, you need coverage that doesn’t add heat. The men’s METARUN® SINGLET and women’s ROAD TANK each use ACTIBREEZE™ technology to keep you cool. These sleeveless tops—seamlessly constructed from a lightweight, quick-drying knit to prevent chafing—feature strategically engineered ventilation zones at your sweatiest spots to increase airflow and help regulate body temperature on even the most brutal long runs. Prefer more coverage? The METARUN® SHORT SLEEVE TOP features the same tech with shoulder seams designed for easy freedom of movement.

Let your legs breathe

Scorching temps deserve lightweight shorts with the storage you need for must-have essentials. The high-cut design and premium stretch fabric of the women’s METARUN® SPLIT SHORT liberates your stride, while the ROAD 3.5IN SHORT (and the more compressive 2-N-1 model) offers elasticated loops to hold a spare towel or too-hot-to-wear-anymore layers. Men can opt for breezy over baggy a variety of shorts styles, from the no-fuss 7IN PR LYTE SHORT to the ACTIBREEZE™ WOVEN 7IN SHORTS with advanced cooling technology.

Support without sweat

Running is a repetitive, high-impact sport, and the right sports bra can make or break your workout—especially in the heat. The ROAD COMPRESSION BRA helps reduce bounce with chafe-free compression, keeps you cool with a quick-drying fabric, and uses a molded spacer to provide structure and breathability compared to traditional foam padding. Need more convincing? The easily accessible side mesh pocket makes it even easier to stash your essentials.

Keep your feet cool

With higher temps and increased humidity, traditional cotton socks may not cut it. The good news is that technical socks made from synthetic blends—like the WOMEN'S QUICK LYTE PLUS socks or the ASICS SPEED NO SHOW socks—can help you go the distance in comfort. The former delivers targeted cushioning while the latter is crafted from a moisture-managing knit designed to keep your feet dry.

Cap off your outfit

A hat is one of the simplest ways to keep yourself cool on a run and protect your head and face from the sun. The PERFORMANCE CAP is made with quick-drying and stretchy material for comfort, while the PERFORMANCE RUN 5-PANEL CAP features a lightweight, sleek 5-panel silhouette. Lastly, the BUCKET HAT was specifically designed for runners with mesh paneling and moisture management properties for airflow and ventilation.
