With half of its material coming from pre-consumer recycled sources, POLAR marks a step on our journey of sustainability – though we tested the textile extensively to ensure sustainability doesn't come at the cost of insulation, breathability, or body-wrapping elasticity.The external rollBar bib strap construction is adapted from the Racing Series, adding locked-in security to the GT S11's endurance-tuned fit – streamlined, stable, and dialed for all-day comfort. The GT S11 Insert also benefits from trickledown RS technology, combining the rider-favorite MILLE insert with a soft, pressure-relieving Sundeck panel.Specifications:- Compositions: Main Fabric 86%Polyamide 14%Elastane, Padding Insert 85%Polyester 15%ElastaneTechnology:Featured Fabrics:- POLAR is a midweight (250g/m²) warp-knit textile with a soft, brushed inner face that creates low-volume loft to trap warmth without bulk.
