Women's sports underwear (trail running)

The right underwear makes a big difference on the trail. Whether you're doing a short training run or an ultra: good technical sports underwear prevents irritation, wicks away moisture and lets you focus fully on the trail.

What is sports underwear for trail running?

Women's sports briefs are specially designed for intense effort. They offer a close fit, stay in place and minimise friction. Thanks to technical materials, they stay comfortable even on long runs.

When do you wear sports underwear?

• On every trail run, short or long
• In warm weather, to wick sweat away effectively
• Under shorts or tights without a built-in liner
• During races and long distances

Good underwear is an essential part of your kit, even if no one sees it.
