The right sports underwear can make a real difference to both comfort and performance. Whether you’re running, cycling, practising yoga or lifting weights, it’s all about finding garments that support your body – without holding you back. Today, sports underwear is not just about fit, but also about technology, materials and design working together to give you the best possible experience.

Why sports underwear matters

When you move, your body works hard – and so should your clothing. Sports underwear needs to handle sweat, friction and movement while providing support where it’s needed most. For women, a well-fitting sports bra can prevent discomfort and even injury. For men, the right level of support can make training more comfortable and effective.

Good sports underwear helps regulate body temperature, wick moisture away from the skin and reduce the risk of irritation. That means you can focus on your workout instead of worrying about chafing or tight seams.

Materials that move with you

The best sports underwear is made from technical fabrics that combine breathability, stretch and quick-drying properties. Synthetic fibres such as polyester and polyamide are popular because they efficiently draw sweat away from the skin. Many brands blend these with elastane to add flexibility and freedom of movement.

Merino wool is another excellent option, especially for outdoor activities and longer sessions. It naturally regulates temperature and resists odour, even after hours of wear.

Whatever the material, look for seamless construction or flatlock stitching – both reduce friction and create a smoother feel against the skin.

Support without restriction

One of the biggest challenges in sports underwear design is finding the balance between support and freedom of movement. For women, this often comes down to choosing the right sports bra. There are three main levels of support:

• Low support – for gentle activities such as yoga, Pilates or walking.
• Medium support – for workouts like cycling, dance or strength training.
• High support – for running, team sports and other high-impact activities.

For men, underwear should fit snugly without feeling tight. Many prefer compression-style boxers or tights that support the muscles and reduce movement, while still allowing full flexibility.

Fit and freedom of movement

Good sports underwear should feel like a natural extension of your body. It shouldn’t ride up, roll down or dig in. Always test it in motion – bend, stretch and jump – to see how it moves with you.

Elastic waistbands, wide straps and ergonomic cuts make a big difference. Many brands now offer designs tailored to different body shapes, so you can find the fit that suits you best.

Care and durability

Sports underwear goes through a lot, so proper care is essential. Wash it at a low temperature, avoid fabric softener (which can damage moisture-wicking properties), and let it air dry. This helps maintain elasticity and performance for longer.

If you train regularly, it’s worth having several sets so you always have a clean one ready – and to give each garment time to recover between uses.
