Regulating your temperature is key to performance, and a good base layer is key to regulating temperature in cooler/cold weather. The Louis Garneau SF-2 Plastron Base Layer is lightweight, but ultra effective. The Supra Filo 2 mesh creates a barrier where moisture escapes and regulated air stays next to your skin allowing you to layer up for the cold without soaking yourself into clamminess.
