Versatility that unleashes freedom of movement. 

June 01, 2018


Versatility is paramount during a climb. Having the confidence to move freely and adjust to your environment are factors that are impossible to overlook. New from Arc’teryx for spring 2019, the Sigma SL Anorak delivers freedom of movement in a lightweight, versatile and compact package. From bouldering and multi-pitch to alpine days, the new Sigma SL Anorak is designed for climbers who are always reaching higher.

• Superlight, highly air-permeable and abrasion resistant softshell

• Deep front zipper for easy on / off and rapid ventilation

“This is my new go to when I’m headed to Squamish to climb with friends after work. It’s incredibly comfortable and the stretch fabric really allows me to move and climb confidently.” Brylee Geddes – Ascent Designer.


An ideal climb is one where the weather is no issue. However, anyone who has experience climbing knows this is not always a reality. A climbing softshell that grants weather protection is paramount. With this in mind, the Sigma SL Anorak is constructed with Aequora Airperm™, a lightweight, durable and air permeable fabric with water resistance, to keep climbers protected during uncertain weather. This edition of Aequora Airperm™ also incorporates elastane, for enhanced mobility. With trusted protection and increased mobility, its an anorak that covers all the bases.


The Sigma SL Anorak features a deep front zipper that allows for rapid ventilation during an intense climb and extends just low enough so that it doesn’t intrude into harness territory. Dual hem adjustments and HemLock™ technology keep the jacket tucked under the harness while climbing. All small essentials are conveniently within reach in the external zippered chest pocket, and the adjustable, helmet compatible hood can be rolled up and stored away when not in use.
