Winter’s chill needn’t put your fitness commitments on pause. We’ve scoured the market for the best women’s winter base layer tops to keep you snug while engaging in various outdoor activities such as running, hiking, or skiing.

Understanding Winter Base Layer Tops

These close-fitting tops, worn directly against the skin, serve as the primary layer in your activewear ensemble. Rather than causing you to overheat, they stabilize your body temperature, keeping your muscles warm during your workout.

Key Features of base layer tops include sweat-wicking technology, meaning they absorb sweat from your body for it to evaporate, ensuring you stay dry and comfortable during your outdoor activities.

Finding the Perfect Base Layer Top

Choosing a winter base layer top depends primarily on your sport, the climate, and whether you plan to wear additional gear over it. The right base layer keeps you snug without suffocation. Aim for a good stretch in the fabric for a comfortable fit.

Material wise, aim to strike a balance between heat retention and dryness, as explained by popular pentathlete Suzie Cave. She suggests opting for nylon, polyester, and merino wool over cotton.
