A windproof & water-resistant shell vest that provides core coverage for variable conditions in spring & fall or on long chilly summer descents. Blending increased protection on the front & increased breathability on the back the reengineered UMA GTV Spring Fall Vest is more versatile than any UMA Vest we’ve ever produced. It features two new technologies: a windproof waterproof & thermal membrane from our new Airblock line across the chest shoulders & sides & a rear panel of our new ultrabreathable VENTAMESH textile. The abdomen panel & collar maintain thermoregulation with the lightweight insulation of RX EVO Light. The combination of protection on the front panel & aggressive breathability & heat-dissipation on the rear panel maintain the ideal personal microclimate in cool variable conditions. The revised fit layers well over summer-weight jerseys or the GT Spring Fall Jersey C2 adding versatile protection to any layering system. 60% Polyamide 21% Polyester 19% Elastane
