Just as fast as racing naked.

While they already fit like a second skin, the Free Aero Shorts go a step further and incorporate dimpled fabric at the outer panels to move air much like the surface texture of a golf ball. The seat and front panels are constructed from a breathable fabric so you won’t overheat. Both fabrics are 30% Lycra, which lends a compressive quality to the fit to keep your legs rejuvenated. All the seams are flatlock stitched to minimize chafing.

The bib shorts are held in place by Castelli Carré straps. This design features breathable mesh that culminates in Carré fabric in a yolk over your shoulders. This keeps the straps tight, yet comfortable, against your torso to avoid unnecessary wind stifling bulges.

In subtle Italian style, the shorts feature Castelli red accents on the leg grippers, reflective squares on the rear of the legs and iconic scorpion logos.

  • 30% Lycra, dimpled side panels to reduce wind drag
  • Race fit with light compression
  • Progetto X2 Chamois
  • Carré yolk bib straps provide hem-less comfort on your shoulders
  • Giro Air leg grippers
  • Reflective accents

Quadzilla Beware - Runs Small

  • Familiarity: I returned this product before using it

I usually wear a Large in Castelli bibs. I read the reviews and decided to size up and went with the XLs. These things are still too small and I'm 6'/190(33waist/32inseam) with muscular thighs/butt. I like my clothing snug/race fit, but these bibs are very constricting on the legs and crotch. If I went with the XXL, the length would be longer than I like. Really bummed...these things are quality material and well made.

awesome bibs

  • Familiarity: I've used it several times

This bibs are great but run smaller then other Casttelli ordered med but had to exchange for lg. The chamois is great and your butt will thank you. I have used them on three 30 mile rides and they performed very well.
