Quick Answer
While athletic wear can provide some initial warmth, it may not be sufficient as a base layer for winter activities, especially in extremely cold conditions, as it often lacks the moisture-wicking and insulating properties of dedicated base layers.
Choosing the Right Base Layer
When it comes to winter activities, the base layer is crucial for maintaining body heat and preventing moisture buildup. Dedicated base layers are designed to wick away moisture from your skin, dry quickly, and provide thermal insulation. Look for fabrics like merino wool, synthetic blends, or silk, which offer excellent moisture-wicking properties. For example, merino wool base layers can retain their insulating properties even when wet.
Base Layer Options for Winter
For winter activities, consider a base layer with a high thermal rating, such as a weight or thickness of 200-300 g/m². This will provide sufficient warmth without being too bulky. Also, consider base layers with a high number of moisture-wicking fibers per square inch, such as those with 400-500 fibers per square inch. These will help maintain dryness and prevent cold spots.
Athletic Wear as a Last Resort
If you don’t have dedicated base layers, athletic wear can be used as a last resort in mild winter conditions. However, expect a significant decrease in performance and warmth. Also, be aware that athletic wear may not dry as quickly as dedicated base layers, which can lead to discomfort and cold spots. In extreme cold, it’s better to invest in a dedicated base layer or consider alternative options like a fleece or woolen sweater.
