Castelli

Unlimited Limited Edition Bib Tight - Men's

What Our Gearhead® Experts Are Saying:

“I’ve put in serious miles with these tights on cold, wet gravel routes and they haven’t let me down. Between the storage, comfort, and water resistance, it’s one of the most versatile bottoms I own.”

Crafted for adventure beyond the pavement, the Unlimited Trail Bib Tight from Castelli is designed to balance protection, comfort, and function. At the core is Nano Flex 3G, a thermal, water-repellent fabric that shields against road spray and light rain while retaining exceptional breathability and stretch. It's built to perform in variable conditions, ideal for rides ranging from early-morning chill to damp winter gravel grinds.

Its practical storage, two large thigh-mounted cargo pockets, provides accessible space for snacks, tools, or your phone. Underneath, Castelli’s Progetto X² Air Seamless chamois delivers pressure-relieving support and all-day comfort, even on the most rugged bikepacking missions. Finished with minimalist seaming, wide ankle openings, and a secure regular fit, the Unlimited Trail Bib Tight is a key piece in the gravel rider’s cold-season kit.
