The Q36. 5 Gregarius Hybrid Light Bib Tights use a nylon-elastane blend built light enough for a shoulder-season ride, holding a form-fitting cut that doesn't add bulk once the day warms up. A women-specific moulded chamois shapes itself to the rider's own saddle contact points, keeping comfort consistent whether the ride opens cold or closes warm. What Our Gearhead(R) Experts Are Saying:"I start a fall morning cold and end the ride sweating through a warm afternoon, and these never feel like the wrong tight for either end of that swing."
