Castelli has had a long history of ruling the roost in $150 bib short category and their Endurance bib shorts are positioned to firmly keep them on top. Castelli made the Endurance to handle your longest rides with the winning combination of top end materials, comfortable pad, and a fit second to none. Value-conscious shoppers should note this is Castelli's least expensive bib with the Progetto X2 pad.
Action Micro fabric with ProSecco treatment is form fitting with the perfect compression as well as abrasion resistant. ProSecco treatment pulls moisture away from the skin to the surface over a larger surface area for quick evaporation. Giro3 leg grippers and the extraordinary Progetto X2 seat pad make sure this one's made to go the distance.
The Progetto X2 Air chamois delivers excellent breathability and features a soft, stretchy, seamless, bacteriostatic layer next to the skin that prevents chafing. A cushioning layer put the padding in just the right places being thin at the edges gradually increasing to maximum thickness underneath the sit bones. Additional perforated viscous padding is located underneath the ischial bones and the sensitive perineum area.

This is the least-expensive Castelli short that still has the outstanding Progetto X2 chamois. The Progetto X2 is top-quality, comparable in quality to the Assos S5 Uno. It was great of Castelli to make these relatively rough-hewn shorts with their top chamois, so you can feel great and not spend $250 . I have several pairs of these to stand in for Assos while the Swiss Franc is completely out of control. If you're used to buying shorts that cost more then your saddle, give the Endurance bib a try.
Pros: Progetto X2 chamois; low price
Cons: relatively less technical fabric, stitching
