Assos Equipe RS Winter Bib Tights S9

Low-volume winter bib tights that merge targeted protection, maximum breathability, and an aerodynamic fit for riders going full gas in the coldest conditions.

For cyclists who prefer winter training outdoors, these are less a pair of tights and more a well-engineered toolkit of solutions for the problems associated with cold-weather cycling. They keep you off the trainer and connected to the road with a suite of technologies combining our S9 racing platform with the next evolution of our Winter 3/3 seasonal innovations. The result is the best fitting and most supportively compressive weatherproof bib tights we've ever pulled on. Light precipitation, knifing wind so frigid you can see it, and chamois-stinging road spray—any of them can prematurely end a winter ride, but these tights are engineered to stop them all.

Though OSMOS Heavy, a stretchy insulator, constitutes the tights' body, the key textiles are our membrane-equipped SPHERE Ultra and SPHERE Medium. The weatherproof SPHERE panels are situated on the knees, thighs, hips, crotch, and lower back. Taped seams and DWR treatment are further proof against watery ingress.

Our aeroFit is the most aggressive, most aerodynamic, most compressive, and—simply—the fastest option in our racing line.
