On chilly days that we’re looking to break up the monotony of riding indoors on the trainer, the Castelli Velocissima TH Tight gives us that extra little push to head outside and put in those winter miles. The fleecy interior of the Thermoflex fabric is super breathable and traps a warm layer of air against our skin to help fight winter temperatures and keep us out on the road longer. The KISS Air² Donna dual-density chamois is designed for peak comfort and allows for unrestricted movement without bulk. Reflective details keep us seen as the days grow shorter too.
