Runderwear: Run in Comfort, Perform with Confidence

From Runners, for Runners

The Runderwear story began in the UK with two passionate runners who wanted better gear for long distances. They realised traditional underwear caused chafing, discomfort, and distraction during runs. So, they designed seamless, high-performance pieces that solved those issues.

Word spread quickly, and Runderwear became a trusted name among athletes. Their mission has always been clear: create underwear and bras that allow you to run chafe-free, with maximum comfort and support.

A Range That Works Hard for You

The Runderwear collection is built around performance and comfort. Their sports bras are a standout, designed to reduce bounce, wick away moisture, and stay supportive through every stride. Whether you need a high-impact sports bra for running or a lighter option for training, there’s a Runderwear sports bra that fits your needs.

The brand also offers sports underwear including briefs, hipsters, and shorts — all seamless, breathable, and made to prevent chafing. Fabrics are lightweight and quick-drying, so you stay cool and comfortable no matter the distance.

Why Women Love Runderwear

Women love Runderwear because it delivers what it promises: comfort that lasts from the first kilometre to the last. The seamless design means no rubbing, no irritation, and no distractions. Supportive Runderwear sports bras let you focus on your performance, not your chest.

Their underwear stays in place, moves with your body, and feels soft against the skin. Many women also appreciate the thoughtful touches, like breathable mesh panels and ergonomic fits tailored for running. It’s activewear made by runners, for runners — and it shows.

With Runderwear, you don’t just wear sports underwear. You wear confidence, freedom, and peace of mind, knowing nothing will hold you back. That’s why runners love Runderwear from training through to race day.

Common questions

Are Runderwear sports bras comfortable and chafe-free during long runs?

Runderwear sports bras are designed with running comfort in mind.

Many styles feature soft, breathable fabrics and smooth construction to help reduce rubbing.

Moisture-managing materials also help keep you comfortable when sweating.

However, no sports bra can guarantee you'll never experience chafing. Getting the right fit is especially important for longer runs.

For helpful fitting advice, visit our Sports Bra Hub.

Are Runderwear sports bras good for running and high-impact exercise?

Yes! Runderwear sports bras are designed with runners in mind, offering support during high-impact activities.

Their supportive designs help reduce breast movement during running, HIIT and intense workouts.

However, support levels vary between styles. Always check the recommended activity level before choosing.

Need help finding the right support? Explore our Sports Bra Hub.

Are Runderwear sports bras suitable for women with larger breasts?

Yes! Runderwear offers supportive running bras, including designs suitable for fuller busts.

Look for firm underbands, supportive cups and adjustable straps. These features help reduce breast movement during exercise.

However, cup-size availability varies between styles, so check the product's size range.

For running, choose a bra offering appropriate high-impact support.

How do Runderwear sports bras fit, and are they true to size?

Runderwear sports bras are designed for a snug, supportive fit. However, sizing can vary between styles.

Your band should sit firmly around your body without riding up. The cups should comfortably contain your breasts without spilling or gaping.

You should also be able to breathe freely and move comfortably.

Always check the individual product's size guide before buying.

What's the difference between Runderwear sports bra styles, and which one should I choose?

Runderwear offers different sports bra designs to suit your breast size and running preferences.

Some feature padded cups for additional shaping, while others offer a lighter, non-padded feel.

Adjustable straps and different fastening options can also affect comfort and fit.

Choose a style that provides the support you need without restricting movement.
