Care Instructions
- Wash sweaty workout gear as soon as possible after use to prevent sweat buildup.
- Machine wash at 30–40°C (86–104°F) with similar colours.
- Use a liquid detergent, preferably one designed for sportswear.
- Avoid fabric softener, as it can reduce breathability and stretch. For a natural alternative, use laundry vinegar to refresh your gear.
- Air dry your sportswear. Avoid tumble drying, as high heat can damage elastane fibers.
- If ironing is necessary, use a low temperature setting and avoid ironing over prints.
