The Trilogy System Jacket is designed for riders who extend limitations and who seek out high-intensity challenges, offering protection in rough environments and versatility for functional riding at any level. The Trilogy System is composed of an outer shell that is treated with Obermeyer's HydroBlock Pro coating that is highly waterproof and refreshingly breathable and a component that is pumped full of High-Loft insulation that you can zip right into the shell. If it's getting a little toasty in the jacket, easily remove the component for a little breather, and then zip it back in when the sun goes down and the temperatures drop. Designed with modern alpine styling, razor-sharp seam lines, and an unsurpassed masculine fit, the Trilogy System is a polished performance ski jacket.
