Men's Long-Sleeve Running Shirts

Home Apparel Men Long Sleeves

The long-sleeve running shirt is the most versatile piece in a runner's wardrobe: warm enough for cool fall and spring mornings, breathable enough not to overheat once the pace picks up. Our technical men's models — 2XU, Brooks, Mizuno, Smartwool and more — wick sweat and keep you at temperature, worn alone or as a mid layer.

The ideal shoulder-season top

Between roughly 0 and 12°C, a long sleeve often stands on its own. Look for a technical moisture-wicking fabric, flat anti-chafe seams and, depending on your runs, thumbholes at the wrists or a high collar for wind protection.

Technical shirt or base layer?

The long-sleeve shirt

Worn alone as a first layer in cool weather, or over a t-shirt when the temperature drops. It's the most versatile everyday choice.

The base layer

More fitted and close to the body, worn under other layers in deep cold. For winter, explore our base and mid layers.

Merino wool for temperature regulation

Merino wool shirts, like those from Smartwool, regulate temperature, limit odour and stay comfortable on long runs — an excellent four-season option.

Frequently asked questions

At what temperature should I wear a long-sleeve shirt?

Between roughly 0 and 12°C, a long sleeve often stands on its own. Colder, wear it over a t-shirt or base layer; warmer, a t-shirt is usually enough.

What's the difference between a long-sleeve shirt and a base layer?

The long-sleeve shirt is versatile and often worn alone. The base layer, more fitted and close to the body, is designed to be worn under other layers in deep cold.

Are merino shirts too warm?

No. Merino wool regulates temperature: it keeps you warm in cool weather and stays breathable as effort heats you up. It also limits odour on long runs.

What are thumbholes for?

Thumbholes at the wrists keep the sleeve in place, cover the back of the hand and block drafts — handy in cool or windy weather, especially without gloves.

Can I wear a long sleeve in summer?

Yes, in very light versions: they offer sun protection on long runs and suit cool mornings. Go for a thin, highly breathable fabric.

How do I care for a technical running shirt?

Wash cold, skip fabric softener (it clogs breathable fibres), and air dry to preserve moisture-wicking performance and the garment's life.
