- Wash: Machine wash cold on a gentle cycle with similar colors.
- Detergent: Use a mild detergent—avoid bleach or fabric softeners to protect the fabric’s performance features.
- Dry: Tumble dry on low heat or hang to dry for optimal results.
- Iron: If necessary, use a cool iron. Do not dry clean.
