When words like endurance or long distance are used to describe a cycling short, it generally means they are going to be built with less compression for a less restrictive feel. In most cases, it will also mean the short's cut will be slightly larger and more voluminous to accommodate a bigger body type. All of the latter is true with the Endurance X2 Short. Castelli was wise enough to add enough elasticity so they fit just about everyone, not just larger riders. Add the best seat pad that Castelli produces and bring the price in at under $130 and you can see why it is one our best-selling shorts.
The Endurance X2 is constructed from 8 panels, each of which are anatomically cut and made from Endurance Evolution fabric. This compressive, but less restrictive fabric offers a good blend of muscle compression and comfort. It also provides excellent moisture control through push-pull perspiration wicking. The leg grippers are Castelli's proven Giro++ design and give a natural feeling extension and termination of the garment on your thighs. The Giro++ gripper manages to stay attached to your thigh without binding or applying too much pressure.
These shorts are finished off with the amazing Progetto X2 insert. This elastic insert features a two piece construction. The first piece is the base. This is the working part of the chamois which has three gel areas that are located at your sit bones and soft tissue areas and is sculpted for an anatomic fit. The second is a skin care layer that is bacteriostatic, soft and seamless to prevent chafing. When you combine these two parts into one unified chamois, you get one of the best cycling inserts ever produced. Due to the construction of the insert, you can pin the chamois into the bibs prior to stitching for a perfect, non-wrinkled fit.
