Castelli claims the Meno Bib Tights are among the simplest products in its entire lineup, but that's very different than saying they're basic or unsophisticated. Rather, the reason the Meno is simple is because that's how Castelli thought it could get the most benefit with the least fuss, which should be, after all, the goal of all technical cycling gear. The Meno is made of just four separate pieces of fabric. In the front, two Thermoflex Core2 panels provide lightweight warmth and compressive support, while two light and stretchy Thermoflex back panels provide unhindered mobility and moisture wicking properties. Flatlock seams join the four panels in an anatomic shape to decrease restriction, while the mesh bib straps provide lightweight and breathable support that doesn't interfere with your torso layers. At the ankles, Giro3 grippers form a snug seal while reflective locking zippers make the Meno easy to get on and off. Lest we forget, the Meno also features a KISS3 chamois, which provides lightweight and flexible protection for rides of all lengths. It's also the same chamois featured throughout much of Castelli's summer kit, so you can worry about ticking off the base miles without breaking in a new chamois.
