Attention to functional protection creates a design focused on climbing. Utilizing a superlight, durable yet highly breathable material, the Sigma SL Anorak gives unrestrained movement and elevated performance in a softshell pullover for comfortable, confident climbing. Superlight and breathable Aequora Airperm fabric gives wind protection and durability against rock. The deep front zip makes access easy and increases air flow during streneuous climbs. The fully adjustable, helmet compatible hood sits comfortably when climbing and doesn't restrict vision. The Sigma SL Anorak is the sum total of Arc'teryx designers responding to the needs of our climbing community.
