Castelli Endurance 2 Bib Shorts

A Castelli favorite, Endurance Bib Short now has a new bib design, improving on the original design. If you look for certain descriptive buzz words in cycling apparel products, it helps you better understand the design and purpose of the particular garment. In this case, when words like endurance or long distance are used in a bib short, it generally means the bibs are going to be built with less compression for a less restrictive feel. In some cases, it will also mean the bib cut will be slightly larger to accommodate a bigger body type. All of the latter is true with the Endurance 2 Bib 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 $150 and you can see why it is one our best-selling bibs.

The Endurance 2 is a multi-panels construction, anatomically cut and sewn to complement body movement and muscle function; 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 Giro3 design and give a natural feeling extension and termination of the garment on your thighs. The Giro3 gripper manages to stay attached to your thigh without binding or applying too much pressure. The upper features an updated bib strap construction with mesh back and Y-tapered straps. Wide suspender bands do a nice job at spreading out the load and stress.

These bibs are finished off with the updated Progetto X2 Seamless insert. This elastic insert features a two-piece construction that has no seams. The first piece is the base. This is the working part of the chamois which has three air cooled padded zones that are located at your sit bones and soft tissue area 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.
