The Bilt Brea Women's Jackets main functions are to keep you comfortable in most weather and protected when riding. Four direct to body vents on the sleeves and back ensure enough ventilation gets to the rider on warm summer days while the option of a full sleeve zip in liner can keep out the brisk fall air. CE Level 1 elbow and shoulder armor with a pocket to add a back protector keeps riders safe if the ride gets treacherous.
