Care Guide
Special Notes
• Reshape while damp
• Use cedar blocks for moth prevention
Additional Care Tips
- • Hand wash cold (30°C/85°F) or machine wash on wool/delicate cycle with wool-specific detergent
- • Never tumble dry — lay flat on a towel and reshape while damp
- • Iron on low-medium heat with steam using a press cloth to avoid shine
- • Store folded with cedar balls or moth repellent sachets — wool is a moth target
- • Avoid bleach and fabric softener — both damage wool fibers
- • Air out between wears; wool is naturally odor-resistant and needs less frequent washing
