Rossignol SAS S4 Squindo Skis - Sin number 4 Anger - Rossignol brings you fine tuned fury in the SAS S4 Squindo Skis. Splatter on some steez, Andreas Hatveit and the S4, eat the competition for lunch, whether skiing in rail jams, slope style and super pipes. The Rossignol SAS S4 Squindo Skis were created with a dual wood core, a hybrid of two separate woods that give you incredible feel in the park and offer all mountain flex. You will covet Rossignol SAS S4 Squindo Skis when you learn they have a weight reducing system (WRS). Candide Thovex helped develop the WRS concept for this super lightweight jib ski.
