Look, we're not saying that you need a different pair of bib shorts for every variation of inclement weather. But, for those of you who live in more temperate climates, you're not going to need full-length bib tights more than a week out of the year -- California, we're looking at you. So, when you're riding in weather that's cold enough for the shivers, but doesn't warrant a parka on your legs, slip on the Giordana Silverline Super Roubaix Bib Shorts.The Super Roubaix Bib Shorts are made from the patented Super Roubaix fabric. Like all fabrics in the Roubaix family, Super is a winter-weight microfiber that uses an interlocking knit construction. With a fit and external feel similar to standard Lycra, Super Roubaix provides a thicker knit and cozy, fleecy feel against the skin. And not to be counted as a one-trick, warming-only pony, Roubaix efficiently moves moisture away from the skin and retains a high breathability. For extra ventilation, the bib upper has a large micromesh insert on the back. After all, it's hard to stay warm if you're sopping weight. For comfort and warmth, the inner-lining features a brushed surface that creates insulating air pockets that retain body heat. The paneling for the bib shorts is patterned from the popular Silverline summer line, and accordingly, it has a precise fit that won't wrinkle or bunch.For comfort in the saddle, Giordana included its MC-3 OmniForm chamois. MC-3 is molded with Giordana's high frequency OmniForm technology that removes irritating seams and uncomfortable density clusters. The end result is a chamois with a variable density that feels like it's been molded to your body. It allows a complete freedom of movement, free from abrasion or chafing.The Giordana Silverline Super Roubaix Bib Shorts are available in the color Black and in five sizes from Small to XX-Large.
