The Q36.5 Gregarius Hybrid vest provides essential insulation and protection against cold winds for a wide range of intensity conditions. The construction focuses on a comfortable fit that offers space for colder outings, while its weight makes it a practical addition for summer rides that may extend into the evening chill. It utilises combined materials with a tailored cut to offer wind protection and insulation from low temperatures without a bulky and constrictive fit. The chest and shoulders employ a high-density knit material that effectively prevents wind penetration without resorting to non-breathable synthetic membranes. The result is a breathable fabric that allows excess heat to escape while protecting against cold winds. To enhance breathability and thermoregulating properties, the centre of the back uses a fabric that prevents the torso from overheating and allows sweat to evaporate quickly.
