Learn how to wash and maintain your Grey Runner Sports Shorts and Black Overdyed Short Boxer to preserve color, fit, and fabric performance.
Quick answer
Wash both items separately in cold water with mild detergent, air dry the shorts, and tumble dry the boxers on low to preserve color and fit.
Why separate care matters
The Grey Runner Sports Shorts use Action Tech® fabric (95% polyester, 5% elastane) that wicks moisture and resists bacteria. The Black Overdyed Short Boxer has a distinctive faded finish that can bleed if washed incorrectly. Combining care methods ensures each garment performs as intended.
Step-by-step care routine
- Turn garments inside out: Turn both the shorts and boxers inside out before washing. This protects the outer surface and reduces friction on any prints or finishes. A common mistake is leaving them right-side out, which accelerates fading and fabric wear.
- Wash in cold water on a gentle cycle: Use cold water (below 86°F / 30°C) and a mild liquid detergent. Avoid bleach, fabric softeners, and stain removers that can damage elastane or alter the overdyed color. Hot water can shrink the elastane and cause the black dye to bleed unevenly.
- Air dry the shorts, tumble dry the boxers on low: For the Grey Runner Sports Shorts, hang them to air dry away from direct sunlight to preserve the Action Tech® fabric. For the Black Overdyed Boxers, tumble dry on low heat only—remove while slightly damp to avoid over-drying. High heat ruins elastane elasticity and can set wrinkles in the boxers.
- Store flat or folded, not hung by waistband: Fold both items and store them in a drawer. Avoid hanging them by the waistband, which can stretch the elastic over time. Hanging by the waistband is a common error that leads to sagging and misshapen garments.
