Pack a durable, ultra-warm midlayer wherever you go with the Oakley Men"s Beltline Primaloft Insulated Jacket. Filled with water-resistant and highly compressible PrimaLoft Sport, the Beltline fits in the zippered chest pocket for quick storage and easy transport. Pertex Quantum has an incredible strength-to-weight ratio, a feel that is as soft as gossamer silk, and the smallest packing volume of any Pertex fabric, making it the perfect choice for a lightweight and durable body material. An internal storm flap enhances the wind and weather protection without being cumbersome. The OOR hood is designed with comfort and warmth in mind with a two-way adjustable drawcord and a storm-guard brim to trap in heat. Elastic binding in the cuffs secures the sleeves in place without adding the unnecessary bulk of straps or gaiters. As part of the Pro Rider Series, the Beltline jacket has been tested and approved by some of Oakley"s best athletes.
