Some rides start cold, finish warm and spend several hours somewhere in between. For those conditions, ASSOS of Switzerland introduces the EQUIPE ThermoBooster P1, a lighter and more packable evolution of its versatile midlayer.
Designed to sit between a jersey and a traditional jacket, the ThermoBooster P1 adds lightweight thermal protection without sacrificing the close, aerodynamic fit of the EQUIPE range. It is made for cool starts, exposed descents and the changing temperatures of spring and autumn, when a jersey is no longer quite enough, but a jacket is too much.
The updated generation uses Hyperlight insulation and the SENS AIR PLUS textile for 360-degree coverage, combining thermal protection with high breathability and low weight. At the arms, 575CX sleeves provide a close, aerodynamic fit that integrates cleanly over the jersey underneath.
A double-slider zipper allows riders to fine-tune ventilation and access on the move, while the new ASSOS A logo and reflective details add a subtle visual signature and increased visibility.
Light enough to pack away when conditions improve and aero enough for racing, the ThermoBooster P1 is designed to be a practical part of the layering system, adding just the right amount of protection when temperatures begin to shift.
