On Performance T Fit and Materials

On cut the Performance T for an athletic fit that stays out of your way.

The short-sleeve T-shirt fits true to size but has a slim fit through the shoulders and chest, which mitigates any excess fabric. It also still has a bit of flowiness through the midsection to increase airflow.

Best of all, though, is the shirt’s lightweight fabric. The fabric is very thin, and its mesh-like weave makes the shirt breathable. One Fleet Feet runner wore the shirt for a run on a hot, humid afternoon, and he could feel the air moving through the fabric.

On designers chose a 100-percent polyester fabric to boost warm-weather performance. The polyester is lightweight and smooth, and it helps pull sweat away from your skin.

Some small but important details are the neckline, sleeves and hem. The edges of the shirt have smooth, flat finishes that lie flush against your skin. The neckline doesn’t bunch up or crinkle, and the sleeves don’t roll up.

The men’s Performance T has a classic crew neck, while the women’s version has a lower-cut neckline that swoops down just below the collarbone.

Light Feel, Excellent Performance

On a sticky, humid afternoon in August, the On Performance T excelled.

One Fleet Feet reviewer says the Performance T was stellar on a day when no shirt was going to stay dry for very long.

“I was dripping sweat a few miles into my run, but the Performance T felt great,” he says. “It still feels light even when it’s soaked through.”

The light weight is one of the shirt’s defining features. On lists the women’s Performance T at 2.31 oz, and the men’s version at 2.98 oz, which is among the lightest running shirts on the market.
