Professionals sport cycling trousers for their performance-enhancement, comfort and warmth. Unlike that of regular clothes, their special flat seaming does not push uncomfortably into your skin. Moreover, the stretchy fabric hugs your muscles in supportive warmth and protects them from the elements.
Models with fleece or other lining provide more insulation, thereby allowing the muscles to function optimally, while those with waterproofing prove ideal in wet weather. Wear proper cycling trousers and stop the weather from dictating your choices.
