BY FIT

The ultimate classic

Boxers Briefs

A true classic, the boxer brief is designed to fit all body types, featuring a medium waist and medium-length legs. This style offers the perfect balance between traditional boxer shorts and trunks—snug at the waist with a slightly longer leg length for optimal support.

Boxer briefs are the ideal everyday choice, offering more coverage than briefs while providing high support around the thighs. The extra fabric between the legs helps prevent chafing, making them a great option for active lifestyles.

Choosing the right size is key—too loose, and excess fabric may bunch up; too tight, and you risk discomfort and chafing.

The perfect middle ground

Trunks

Trunks offer the best of both worlds—a shorter version of boxer briefs that has become increasingly popular. If briefs feel too short and revealing, but boxers feel too long, trunks provide the ideal balance of comfort, style, and support.

With a slightly lower waist and shorter legs that extend just past the crotch, trunks provide a sleek and modern silhouette. Their close fit makes them an excellent choice for wearing under tailored or slim-fit pants, offering support without excess fabric.

Trunks tend to fit best on those with narrower thighs, as the shorter leg design stays in place without riding up. For those with more muscular legs, boxer briefs may offer a more secure fit.

Maximum Support, Minimal Coverage

Briefs

Briefs, also known as Y-fronts, are the shortest underwear style, offering full coverage at the back while keeping the upper thigh and sides exposed. This design provides unparalleled freedom of movement without excess fabric.

With their secure fit, briefs are an excellent choice for men with larger thighs as they eliminate the risk of fabric bunching or riding up. Their sleek design also makes them perfect for wearing under tight-fitting pants, ensuring a smooth and comfortable feel all day long.

Effortless Comfort, Everyday Freedom

Loose Boxers

Designed for those who value comfort and breathability, loose boxers offer a relaxed fit that provides maximum freedom of movement. Crafted from soft, airy materials, they are the go-to choice for those who prefer an easygoing feel without compromising on style.

With a non-constricting waistband and a generous cut, loose boxers allow for natural airflow and flexibility, making them perfect for everyday wear. Whether you're lounging at home or going about your day, they ensure effortless comfort from morning to night.

Underwear Materials

Underwear materials have the biggest impact on longevity, quality and comfort of your underwear. As such, it is important to take a closer look.

MATERIALS

Cotton

Cotton is the most common material when it comes to underwear. It is a natural fiber that is both soft and durable, which means that it lasts a long time and can withstand a lot of washing. Cotton underwear is both comfortable and has good breathability

MATERIALS

Lyocell

Lyocell is a type of cellulose fibre produced from sustainably sourced wood pulp, typically from eucalyptus or beech trees. It is known for its softness, breathability, and moisture-wicking properties, making it an ideal choice for clothing and textiles. Lyocell is produced through an environmentally friendly manufacturing process that uses a closed-loop system, minimizing waste and reducing environmental impact. Additionally, Lyocell is biodegradable, making it a more eco-friendly alternative to synthetic fibres. With its luxurious feel and sustainable production methods,

Elastane

Elastane is a stretchable fiber made from plastic. It is a material that is often added in small amounts to underwear, to add stretch and elasticity that lasts a long time.

Polyester

Polyester is a synthetic fibre that dries quickly and is very durable. Therefore, it is a common material in functional garments such as sports bras and training underwear, as it is both moisture-repellent and highly breathable. Our Sports Underwear is also made from recycled polyester.

Washing instructions for your Björn Borg underwear.

Below you can find some quick tips on how to wash your underpants and underwear in the best way so that they remain fresh and retain their perfect fit for a very long time.

• Björn Borg underpants are washed at 30-40 degrees depending on material and model. You can wash our Sports underwear at 30 degrees.

• It’s a good idea to use a laundry bag when washing underwear, to protect them a little extra.

• If your washing machine has a special program for underwear, feel free to use it for a gentle and customized wash.

• Tumble underwear on low heat or air dry them to maintain the fit.

• Avoid fabric softener as it can wear out the underwear's shape and reduce its breathability. Many underwears are made with microfiber fabrics, fibres adversely affected by fabric softeners.
