Why We Like The Castelli Unlimited DT Liner Bib Short

The Castelli Unlimited DT Liner Bib Short is the ideal liner for underneath our baggy shorts. The women's specific Progetto X2 Air Donna seamless seat pad ensures seated riding comfort no matter how far we go, while the perforated leg panels provide cooling and ventilation. The drop-tail bib strap design crosses in the front or the back, allowing for easy mid-ride bathroom breaks when nature calls.

I've adopted nicer Castelli bibs for the road bike, but was still using Amazon-quality mountain bike bibs. I finally pulled the trigger on these and they are amazing! The mesh venting works great under a pair of shorts. Glad I finally made the switch. The sizing is the same across all Castelli shorts as well, so if you're familiar, no question on sizing.
