Cold weather is mostly a physics problem: your body makes heat, and winter tries to steal it via wind, convection, and damp fabric. A decent base layer helps by trapping warm air close to your skin and keeping you more comfortable whether you’re shoveling, walking the dog, working in an unheated garage, or hiking. Right now, Amazon has solid deals on Cuddl Duds base-layer sets and lounge-ready pajamas. These are more versatile than outdoor-specific base layers, so you can wear them on the hill or on the couch.
