Extreme Salopettes

Share Review this product
The Extreme Salopettes are a serious piece of mountain clothing. First choice amongst leading high Arctic expeditions, these salopettes are regularly used in super cold, hostile conditions. Utilising the same combination of fabrics as the Extreme Smock, they can be worn as a single layer or in truly harsh conditions as part of a layering system. Featuring additional details such as mitt grab tabs and extra reinforcement, the Extreme Salopettes have become a classic cold weather garment. Used by the Catlin Arctic Survey and the British Antarctic Survey Lake Ellsworth Expedition during the winter of 2011/2012.

  • The Extreme Salopettes use 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 40°C/104°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 salopettes 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.
