The next layer to think about is your jersey. In the spring to summer transition, it is important to get this is layer right as it can be the difference between being comfortable and uncomfortable.
On a cooler spring day, look for a jersey like the Castelli Gabba 2 Short Sleeve Jersey. Featuring the revered WINDSTOPPER® technology and branded with the Rosso Corsa label, Castelli’s most premium label, the Gabba 2 is exceptionally breathable and boasts the ultimate weather protection for when the rain draws in. Paired with a set of arm warmers, the Gabba 2 from Castelli proves to be an extremely versatile torso outfit for when the conditions are changeable.
If conditions are looking warm and bright, then a standard cycling jersey is a good option.
