Men's long-sleeve running shirts
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.
