Can I wear thermal cycling pants in the rain?

Thermal pants with DWR coating handle light rain and road spray well, keeping you warm in damp conditions. However, they are not waterproof and will eventually wet through in sustained rain. When thermal fabric gets saturated, it loses most of its insulating properties and can actually make you colder. For heavy rain, wear lightweight rain pants over your thermal pants—this combination provides both warmth and waterproofing. For commuting in wet winter conditions, this layering approach is the most effective solution.
