Men's Running Baselayers

Men's running baselayers are built for the runs where a normal t-shirt is not enough. Cold starts, winter miles, wet pavements and stop-start training all need a first layer that holds warmth, moves sweat and sits comfortably under the rest of your kit.

Shop men's running baselayers at Pro:Direct Running, including men's thermal running baselayers, long sleeve baselayers, lightweight running baselayers, compression running baselayers and cold-weather running layers for daily training, long runs, warm-ups and winter sessions. Find men's running baselayers from leading brands including Nike, adidas, ASICS, New Balance, PUMA and more.

For colder conditions, thermal running baselayers help keep warmth close without adding the bulk of a heavy top. For higher-output sessions, lightweight baselayers work better when you need coverage but still want sweat to move away from the skin. A good baselayer should feel close, smooth and easy to forget once the run settles.

Fit matters because this is the layer closest to your body. A closer baselayer helps reduce fabric movement and makes it easier to wear under a zip top, hoodie or running jacket. Long sleeve baselayers give extra coverage for early starts and winter evenings, while short sleeve or lighter options can work under training tops when the weather is cool rather than properly cold.

Browse men's running baselayers by brand, sleeve length, fabric weight and training use, from lightweight running layers for steady miles to thermal baselayers built for cold-weather running and winter training.
