Castelli Espresso Thermal Bib Shorts As the seasons change, choosing the right kit becomes a fine art, but the Castelli Espresso Thermal Bib Shorts are engineered to be the ultimate transitional garment. Combining premium warmth, exceptional stretch, and luxurious comfort, these thermal bib shorts offer just the right level of insulation for those crisp autumn and spring rides. Designed specifically for a recommended temperature range of 10 to 18°C, they bridge the gap between summer kit and heavy winter tights, giving you the confidence to train hard through unpredictable weather without overheating. Engineered for Premium Comfort and Long-Distance Performance Every detail of these shorts is meticulously made to elevate your riding experience. Built from advanced Thermoflex fabric, they deliver a plush, warm interior alongside an elastic, aerodynamic fit that moves naturally with your pedal stroke. Stretch-mesh bib straps offer optimal ventilation over your torso, maintaining comfort as intensity changes with the rise and fall of terrain. Finished with sculpted raw-cut leg endings that sit flush just above the knee, these shorts eliminate bunching and pressure points.
