How to wash your boxers
so they last.
Temperature, drying, detergent: what keeps the shape and the waistband intact, material by material.
Most boxers can be washed at 30 or 40 degrees, inside out, with a mild detergent and without fabric softener. Pure cotton can often take higher temperatures, styles with elastane, modal or microfibre cannot. What wears boxers out most is heat: a tumble dryer on high heat slackens the waistband and distorts the fabric. The care label is always the reference.
At a glance
Which temperature for which material?
General guidelines. The care label on the garment always takes priority.
| Material | Washing | Tumble dryer | Good to know |
|---|---|---|---|
| Cotton | 40 degrees, sometimes 60 depending on the label | Low temperature | Heat makes cotton shrink |
| Cotton with elastane | 30 to 40 degrees | Preferably air-dry | Heat slackens the waistband and the fabric |
| Modal or viscose | 30 degrees, delicate programme | No | Very soft, loses its shape in heat |
| Microfibre | 30 to 40 degrees | No | Without fabric softener, otherwise it wicks moisture less well |
Step by step
Washing your boxers properly
Seven steps that considerably extend the life of a pair of boxers.
- Read the label before the first wash, especially for styles with elastane or microfibre
- Sort by colour and wash new dark items separately the first few times
- Turn your boxers inside out to protect the colour and the seams
- Use a laundry bag for stretchy styles, especially with jeans or zips
- Dose the detergent as stated on the packaging and skip the fabric softener
- Spin at a moderate speed rather than at maximum
- Air-dry, not on the radiator, and do not iron the waistband
What to avoid
The most common mistakes
Almost all of them have the same result: the boxers lose their shape long before they are worn out.
When to replace
Signs that a pair of boxers has had its day
Even well cared for, boxers wear out. These signs show that it is time to replace them.
- The waistband no longer holds and rolls or slips
- The fabric has become thin or see-through in places
- The shape no longer returns after washing
- Holes or open seams appear
