Shopping for a bib short these days can be daunting, because there are just so many options it is hard to decide which way to jump. If you're having trouble deciding, allow us to point you in the direction of the Castelli Velocissimo Gruppo Bib Shorts. Featuring unmistakably European style and Italian-engineered comfort, these bibs pack a lot of bang for the buck.

Part of the genius behind these bibs is a cut that makes full use of the qualities of the special Affinity Lycra 210GR fabric. The Affinity Lycra is the secret weapon behind many of Castelli's most comfortable pieces because it has a wonderful stretch-return aspect that allows it to give when you need to, but then retakeits shape once you are back in your habitual riding position. Essentially, it moves with you and doesn't fight or rub against you. That's because it has an amazingly soft and smooth texture with an attractive semi-matte finish. Using this fabric in a ten-panel construction means that the bibs will follow your contours so well that you won't even remember you have them on.

Castelli calls the pad in these bibs the Kiss3 chamois, and you'll realize the name suits it as soon as you sit on the saddle. It is nearly as comfortable and advanced as their top-of-the-line Progetto X2, but costs considerably less. They have done this by using all of the same comfort features while saving slightly on the construction. What you'll get is the seamless skin care layer that is made from a super soft brushed microfiber to maximize the luxurious comfort and perfect fit. Since it is seamless, there will be no worries about chafing, while the flexibility of the material will help the pad move with you as you jump to an out-of-the-saddle assault. It has also been given a bacteriostatic treatment to avoid saddle sores and infections. The interior of the insert provides the ultimate in intelligent cushioning so that the maximum padding is placed in the ischial zone, tapering to a moderate thickness in the perineum and then narrowing still further at the perimeter of the pad. The anatomical shape will keep it nuzzled against your undercarriage through every pedal stroke.

On the bibs, Castelli has included super-comfy and airy mesh straps. They will secure the bib in place without tugging, and the mesh keeps them from becoming oppressively hot on a humid, sunny day. The Giro3 integrated leg grippers have been fashioned so that the grip material is knit directly into the short. The generous 5 cm wide band will gently compress to secure the leg hem in place. It also lies completely flat, keeping your leg aero as if it were in a skinsuit. And for those evenings you get caught out after sunset, reflective bands at the back of the legs will help ensure that you'll make it home in one piece.

The Castelli Velocissimo Gruppo Bib Shorts are available in two color options: Black/White and White/Dark Blue. They come in sizes Small through XXX-Large.

  • Giro3 elastic gripper band keeps the shorts from riding up when you start hammering out of the saddle
  • Kiss3 insert combines exceptional moisture management with all-day comfort
  • Reflective hits on backs of legs help keep you visible after dusk
  • Matches perfectly with the rest of the Velocissimo Gruppo kit, right down to the cap and gloves

Great cool bibs for hot summers

    I got these because they were one of the few white bibs I could find. Much needed to keep you cooler during hot summer months in Southern California. Great bibs, fit, and saddle padding. The only critique is the cheesy Castelli logo patch fell off after about two washings. Beware too, that white shorts mean chain grease etc stains that won't come out, but they do mark your red badge of courage.


    Some nice features, tricky sizing

      These bibs are a good value especially with a discount coupon! Nice Castelli fabric and bold graphics. The Kiss3 chamois (same as Presto short) is very comfortable, and the low cut in front is helpful for long rides ... Sizing is tricky however. In Pearl Izumi and Giordana I'm a Medium. With Castelli, not only is the cut smaller/more European, the sizing seems to vary by the type of fabric and the style (race vs club). Order one size up, plus one more just to be sure. I fall between L and XL and it just depends on the style. The guys at RC are terrific about returns.
