Assos has simplified down four base layer models: summer, spring/fall, early winter, and winter. Additionally sizing comes in four options from 0 on the smallest side to III as the largest baselayer. The fibers use the humidity as an insulator or coolant to keep you comfortable on the bike. The general rule of thumb is that the more you sweat, the lighter you should dress, with this spring/fall layer being Assos’s second lightest layer.
This base layer uses an open mesh construction technique to efficiently transfer moisture to your outer layers. It uses a textured yarn with reduced volume to give a near perfect insulating effect, keeping your body temperature steady during the highly weather variable Spring and Fall seasons. You get full freedom of movement, with the garment seamlessly following your position on the bike for added comfort.
