Why We Like The Sigma FL Pant

The Arc'teryx Sigma FL Pant is a lightweight option that we love to bring along for summer mountaineering and alpine climbing. Its Fortius 1.5 fabric is the lightest softshell from Arc'teryx, and it boasts four-way stretch, exceptional breathability, and reliable water-resistance for ideal protection in the alpine during warmer seasons.


  • Lightweight, breathable softshell pant for alpine adventures

  • Double reinforcements ensure long-lasting durability
  • Trim fit includes articulated design for freedom of movement
  • Low-profile webbing belt stays secure under harnesses
