Except for the moisture in the air as the wind blows across all the water in FL and chills you to the bone when the temperatures are lower.
I’ve never felt that jeans keep me warm. They didn’t help us during the various trips we’ve taken in late fall and through winter in FL when it was cold.
I would feel properly packed right now for FL with shorts, shirts, normal socks, wool socks, warm shoes, flip flops, longjohns, running pants with extra layers, sweatshirts, puffy coats, knit caps, warm gloves, and swimsuits.
Everything from my drawers.
