Quick answer
Choose sports underwear for running that is moisture-wicking, seamless, and designed to stay in place. Look for fabrics like MotionTech that dry fast and move with you.
Why your running underwear matters
The wrong underwear can cause chafing, discomfort, and distraction during a run. Moisture-wicking underwear pulls sweat away from your skin, reducing friction and keeping you dry. Seamless construction eliminates pressure points, so you can focus on your pace, not your underwear.
Seamless vs. stitched: what runners need
Seamless underwear is ideal for running because it has no seams to rub against your skin. Stitched underwear can cause irritation, especially on longer runs. If you prefer stitched styles, look for flatlock seams that lie flat.
How to choose sports underwear for running
- Pick moisture-wicking fabric: Choose underwear made from synthetic blends like nylon, polyester, or proprietary fabrics like MotionTech. These materials pull sweat away from your body and dry quickly, preventing chafing and keeping you comfortable. Avoid cotton—it absorbs moisture and stays wet, increasing friction and discomfort.
- Opt for a seamless design: Seamless underwear eliminates the seams that can rub against your skin during repetitive motion. This reduces the risk of chafing and irritation, especially on long runs or in hot weather. Check the tag for 'seamless' or 'no-dig' construction. If seams are present, ensure they are flat and smooth.
- Choose the right coverage and fit: Decide between briefs, thongs, or g-strings based on your preference and the fit of your running shorts or tights. The underwear should stay in place without riding up or bunching. A snug but not tight fit prevents shifting. Test the underwear during a short run first. If you have to adjust it, try a different style or size.
