The Castelli Espresso Thermal Bibshort is a pair of thermal bib shorts designed for cool autumn and spring rides. It bridges the gap between a standard summer short and full-length tights.

Its recommended range is 10 to 18 °C. The Thermoflex fabric provides warmth, stretch and a soft touch, while the raw-cut leg hem sits just above the knee to minimise any interference when pedalling.

Tested by GravelPassion

We particularly appreciated these bib shorts between 12 and 16 °C. The fit is spot on, the length protects the thigh well without causing any discomfort behind the knee, and the pad proved extremely comfortable. Best avoided when the temperature rises markedly, as the thermal fabric makes you sweat quickly.
