GORE Wear's C3 Thermo Bib Tights vary slightly from the C5 line in that they are less water-resistant while still providing extreme weather protection. The thermo-stretch material boosts warmth without holding us back, while the Active Comfort chamois uses GORE WINDSTOPPER Cup Technology to shelter our most sensitive area from arctic blasts yet remains breathable for long-wear comfort. When pedaling on wet roads, the panel up the back protects us from spray. Up top, seam-free, mesh straps sit close to our body, disappearing beneath layers, for ventilating, low-friction comfort.
