Slightly smaller than castelli normally are. The pad doesn’t come forward as much as I would like but def the most comfortable bib shorts I’ve worn to date for long miles.
Product Details
Castelli Premio Bib Short
With a focus on long-distance comfort, the Castelli Premio Bib Short is set to be your new favourite for extended sessions in the saddle. Built on a less-is-more ethos, the minimal branding and sleek design match this garment's premium feel. A reduced number of seams ensures blissful comfort and an irritation-free ride, with the gradient stretch woven fabric being both lightweight and supportive.
As their top of the line insert, the Progetto X2 seamless seat pad is made up of two key components - the soft, skincare layer, and the dual-density foam. This unique construction ensures total comfort from ride start to finish, and reduces pressure in all the necessary areas. The perforated back bib panel is ultra-breathable, and the bib straps design ensures they lie flat.

If you're unfamiliar with your Castelli size, we recommend you go up one size to obtain the best fit possible. Note that you do not need to size up for jackets or vests; please select your normal jersey size.
Castelli clothing is designed for its intended use and should be comfortable when on your bike in a riding position. Your garment should be snug to provide you with moisture-wicking capabilities, as an aerodynamic aid and prevent any fabric from flapping in the wind.
If you require any advice on Castelli sizing, please do not hesitate to contact us.

Reviews
Beautiful bib shorts- My favorite style wise by some distance- treated myself to a co ordinated Navy kit- Feel that I look the part and when I catch a glimpse of my self in a shop window I don't look as muck like a Pro Dart player as I usually do- Definably FASTER - style is worth 50-60 Watts

About Castelli
At the front since 1876.
Castelli has been at the front of cycling apparel since 1876, founded in Milan as the original maker of pro race kit. From the first cycling jerseys to today's WorldTour-proven aero garments, the brand has spent nearly 150 years putting innovation onto the backs of the fastest riders in the world.
Castelli outfitted the first organised cycling teams in Italy and has been a constant presence in the pro peloton ever since. The Scorpion logo appears on more WorldTour podiums than almost any other apparel mark.
