Windshield

Looking for advice for windshield I can pull off and on easily enough. Only want one to make the little lady comfortable. She’s very petite and gets cold easy. I personally don’t want one. But I want to make her happy when she’s out with me cuz I don’t want her cranky. Mostly ride the high desert here in Southern California. Is a full windshield that where to go or will a half windshield work to help deflect the cold air. Thanks
