Is the conventional wisdom on dressing for winter bike rides - namely, layering breathable base layers with waterproof outer shells - actually the most effective way to stay warm and dry, or is this approach more of a product of clever marketing by cycling apparel companies?
Specifically, do the benefits of a breathable base layer - namely, moisture wicking and temperature regulation - outweigh the drawbacks of potentially losing heat and getting chilled by the wind, or would a more insulating, less breathable base layer be a better choice for cold, wet conditions?
Furthermore, is the emphasis on waterproof outer shells - often made from materials like Gore-Tex or similar ePTFE-based fabrics - actually justified, or are these materials more prone to condensation and reduced breathability than manufacturers would have us believe?
And what about the role of accessories like hats, gloves, and booties - are these truly essential for staying warm and dry, or are they more of a nicety for riders who prioritize comfort over performance?
Lastly, are there any alternative approaches to dressing for winter bike rides that dont involve the traditional layering system - such as using a single, highly insulating layer, or incorporating non-traditional materials like wool or synthetic fabrics - that could potentially offer better performance and comfort in cold, wet conditions?
