We’re not out of the 50s today here in Maine and that’s down south at sea level. You want thermals, top and bottom and I would sub the fleece vest for a long sleeve micro-fleece type. I use fleece socks at night to sleep in, never hike in, and alternate two pairs of socks for hiking. I also had “sleeping clothes/town clothes” consisting of a coolmax tank and nylon runner’s shorts with brief. Of your two pairs of shorts, one could be for sleeping. Every one is different. I echo the hat and gloves. I kept a hat my whole hike, it can add a lot of warmth on a cool summer night (which did occasionally happen last year in VA), mine is fleece, weighs nothing.
