Care & Longevity

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.
