A windproof and water-resistant shell vest that provides core coverage for variable conditions in spring and fall or on long, chilly summer descents. Blending increased protection on the front and increased breathability on the back, the reengineered UMA GTV Spring Fall Vest is more versatile than any UMA Vest weve ever produced. It features two new technologies: a windproof, waterproof, and thermal membrane from our new Airblock line across the chest, shoulders, and sides and a rear panel of our new, ultrabreathable VENTAMESH textile. The abdomen panel and collar maintain thermoregulation with the lightweight insulation of RX EVO Light. The combination of protection on the front panel and aggressive breathability and 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.
