Whether you're a dedicated commuter or trainer-ill competitor trapped in the northern hemisphere, the Gore Bike Wear Countdown Thermo Bib Tights offer the warmth and comfort needed to push pedals outdoors. The secret is advanced thermal regulation throughout the tights, including the back and bib.Most tights offer coverage from the waist down, with the bib constructed out of mesh for breathability and leaving upper temperature regulation up to the baselayer/jersey/jacket combination. By using Gore's Themo-stretch fabric for the bib as well as covering the lower back and kidneys, the Countdown Thermo Bib Tights let you eliminate the need for a bulky jacket or added layers -- effectively simplifying your kit.The Countdown Thermo Bib Tights are equipped with the Contest chamois, a well designed, supportive pad for medium to long rides. Its low-profile design, elasticity, and seamless finish won't hamper saddle ergonomics while its excellent breathability will keep you dry and comfortable throughout the ride.Adding to that comfort is the Countdown's form fit and anatomically correct panel shapes. This allows the Countdowns to hug your body without feeling constrictive or binding. At the ankles, gripper elastic keeps the tights from migrating and reflective logos on both calves keep you safe during overcast, low-light rides.The Gore Bike Wear Countdown Thermo Bib Tights with Chamois comes in Small, Medium, Large, X-Large, and XX-Large sizes and one color; Black.
