Midweight insulation for long-distance riding in the cool dry conditions of late spring and early fall – soft breathable thermoregulating and engineered with 50% reclaimed materials. The GT SF Bib Tights S11 debut an all-new eco-conscious textile POLAR which provides midweight thermoregulation with a brushed soft inner face. 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. Composition Main Fabric: 86% Polyamide 14% Elastane Padding Insert: 85% Polyester 15% Elastane Technology overview The finer details FEATURED FABRICSPOLAR is a midweight 250g/m² warp-knit textile with a soft brushed inner face that creates low-volume loft to trap warmth without bulk. The material content is 50% pre-consumer recycled polyamide reducing ecological impact without compromising performance. CONSTRUCTION/FITOur streamlined regularFit and body-contoured shaping reduce seams eliminating friction for total comfort and easy layering. Raw cut waist and ankles finish with a gently compressive bulk-reducing hold. ENGINEERINGrollBar: A patented bracing design adapted from the Racing Series. Stabilizes the insert and locks it in place as your weight transfers while sprinting climbing and cornering. ENGINEERINGzeroPressure Waist: A waist construction developed with a soft highly elastic material to improve the comfort and hold at the waist minus any pressure or pinching. Raw Cut: Race-inspired construction at the ankles and waist that creates a lie-flat finish for unrestrictive comfort and low-volume layering. MILLE GT S11 INSERT:Shock-Absorb Damping Mono 12: Compressive foam layers in a 12mm endurance platform. Thermoformed shaping reduces ridges and irritation. 3D Waffle: A patented three-layer perforated foam that increases breathability and eliminates excess weight. goldenGate 2.0: A free-floating construction that moves with your body rather than against it. New cut-outs on the wings reduce friction throughout the pedal stroke.
