ThermoBooster bib Tights S11 – no insert

The ThermoBooster S11 pushes versatility to the extreme, allowing a number of use cases to adapt throughout winter. For cycling, it layers over your preferred summer shorts without adding the bulk of a second insert. In the most extreme conditions, it adds an additional thermoregulating layer to any Spring Fall or Winter bib tights from the R and TACTICA series. For cross-training, the ThermoBooster adapts to skiing and running, adding an additional element of reflectivity to your workout. However you employ it, the raw-cut finishing and low-volume insulation reduces bulk for layering, unlocking an entire system of winter layering for any outdoor training.
