Special Notes

Densely woven cotton — naturally water-resistant

Re-proof with wax or DWR spray after washing

Additional Care Tips

  • Machine wash warm (40°C/105°F) on gentle cycle with mild detergent
  • Tumble dry on low heat — heat reactivates the water-resistant properties
  • Iron on medium heat to restore fabric tightness and water resistance
  • Do not use fabric softeners — they impair waterproofing
  • Re-proof with wax or DWR treatment if water resistance diminishes
  • Hang to store — avoid compressing for long periods
