The Extreme Jacket uses PERTEX® fabric which contains a Durable Water Repellency (DWR) as the first barrier in keeping you dry. Clean your garment in order to maintain this.
Machine wash in warm water at 30°C/86°F with a mild detergent. MONTANE® recommends Nikwax Tech Wash.
Do not use fabric softeners or bleach.
Do not tumble dry or dry clean. Drip dry only.
Your jacket may need occasional re-proofing to restore the DWR. To reproof the outer fabric always use a spray- never use wash in reproofer. MONTANE® recommends Nikwax TX Direct spray.
