FAQ

The leg length of our underwear varies depending on the style. Here are the leg lengths of some of our most popular alternatives:

  • Organic Cotton Stretch Boxer: 11.5 cm

  • Cotton Stretch Boxer: 10.5 cm

  • Cotton Stretch Trunk: 8.3 cm

  • Bamboo Boxer: 11.5 cm

In Björn Borg’s wide range of underpants, you’ll find both classic cotton underwear for everyday wear and functional sports underwear – perfect during gym workouts and for running.


Choosing the right material is not only about feel – but also about function, breathability, and intended use. Some boxers are better suited for everyday wear, while others are designed to perform during training and movement.

  • For training: Sports underwear made from recycled polyester are preferable thanks to their breathability and moisture-wicking properties – perfect for sweaty workouts.


  • For everyday: Cotton and organic cotton boxers are classic choices for everyday use, with their soft and comfortable feel – a timeless material for underwear.


  • For a luxurious feel: Men's underwear made from LENZING™ ECOVERO™ Viscose, and bamboo viscose are light, soft, and flexible materials that feel cool and comfortable against the skin.

For training, we recommend our Sports Boxers, Sports Trunks and Sports Briefs. Choose the model you prefer, made from materials with features designed for intense activity.


It’s very important that your underwear has a comfortable fit, good breathability and moisture wicking properties that enhance comfort during intense workouts.


Our Sports Boxers are available in several different colors and patterns, and in both shorter and longer leg lengths. If you cycle a lot, for example, a longer leg length helps protect the skin from repeated contact with the saddle, especially when wearing tight cycling tights.


Sports Trunks and Sports Briefs have a tight fit with soft seams, an elastic construction and a chafe free design. The material is quick drying and effectively wicks away moisture.


Different types of training require different features from your underwear. Running calls for lightweight, quick drying underwear with legs that don’t ride up. For example, choose a boxer brief in microfiber fabric with flat seams.


For strength training, you need extra stretch and a stable waistband that moves with you during deadlifts and squats. Explosive workouts like HIIT combine intense sweating with quick changes of direction, so both a secure fit and quick drying properties are essential.


Our sports underwear is made for all types of workouts. It is crafted from recycled polyester and elastane, providing maximum freedom of movement and excellent breathability. In other words, underwear specifically designed for training.

Of course. At Björn Borg, you can buy underwear both as single packs and in practical multipacks. Our multipacks are available in packs of 2, 3, 5, 7, 9 and 12 pairs.

Underwear should sit securely at the waist without digging in, not slide down during the day and provide support without feeling restrictive. If it does, you’ve chosen the right size.

To find the right size, start with your waist measurement and consider how you want the fit to feel. Stretch fabrics adapt to your body and provide added flexibility.

The fit varies depending on the style. Some styles have a tighter fit, while others offer a more relaxed fit.

Our underwear is true to size and fits normally, so you can choose the size you usually wear.

Cotton boxers can be washed at 40°C and tumble dried on low heat. Our sports underwear in recycled polyester should be washed at 30°C and not tumble dried. Here you can read more smart and practical washing tips.
