The Castelli Tutto Nano 3/4 cycling pants are the ideal pants for riding in many different conditions. These cycling shorts are the result of 10 years of intensive development at Castelli. The new Nano Flex 3G fabric is not only extremely warm and soft, but now protects even better against rain. Protecting you against the cold, while also being a good friend on rainy days or when the road surface is still wet after a downpour. Keep in mind that these pants are not completely waterproof, but only protect you against splashing water or a short light shower. The pants have minimal seams ensuring optimal comfort and a perfect fit that fits snugly around the legs. As the suspenders are made of mesh, they breathe well and do not retain moisture when you get wet from a downpour or perspiration. In addition, the fine Kiss Air2 pad ensures that you can sit comfortably in the saddle, even over long distances, without pressure or irritation points. The reflective ends and logos ensure good visibility in traffic. All this makes the Castelli Tutto Nano an ideal pair of cycling shorts to use in many conditions.
