Choose the Right Fabrics. Wool, fleece, and thermals keep you warm. Down jackets are super warm but can feel heavier.
Most heat escapes through hands, feet, and head.Wear gloves, warm socks, and a cap/beanie. A scarf helps a lot on windy days.
People usually focus on jackets but ignore legs. Thermal leggings, warm joggers, or jeans with inner lining help a lot.
Boots, sneakers with good grip, or insulated shoes are ideal
Air out woolen clothes instead of washing them too often
