The suspender fabric is also extremely soft and plush, eliminating any shoulder discomfort or irritation, yet we've still built in a HookUp magnetic bib connection making nature breaks much easier.
The pre-molded, triple-density foam Body Geometry Contour 3D Chamois is contoured to perfectly match the curvature of your body, all while being soft and supportive in all the right places.

There's quite a few boxes that your "favorite pair of bib shorts" must check. The chamois has to be perfect—soft to touch, foam in all the right places, and perfect shape.

The pre-molded, triple-density foam Body Geometry Contour 3D Chamois is contoured to perfectly match the curvature of your body, all while being soft and supportive in all the right places.

A Better Short
Shorts are an obsession at Castelli. They're the most vital piece of clothing and one of the hardest to get right.
Even though the Prima is our entry-level short, it shows that we won't compromise anything for comfort and performance. It starts with the women's-specific KISS Air2 seat pad. Just the name gives an idea of the process of constant improvement, which started with a soft KISS pad that was improved by making it more breathable (Air) and then improved again in the latest update to use the softest-ever top fabric (2). It's ready for your next big ride indoors or out.
We've updated the fabric to the new Pro Dry Soft, which has a smooth matte finish that feels cool on the skin while being very supportive and quick to dry.
We wanted this short to be just right for many years to come, so little details like the reflective patches are stitched in instead of being glued on, and the GIRO3 elastic has the grip woven right into the fabric.
This attention to detail — go ahead and call it an obsession — is why Castelli's entry-level short is just a better short.
- KISS Air2 seat pad for all-day comfort
- Pro Dry Soft matte Lycra is sleek looking and ultra-breathable
- Anatomic construction for perfect fit
- Rear reflective panels
- GIRO3 engineered flat leg band
- 15°-35°C / 59°-95°F
- Weight: 160g
Enduro could be characterized as all-around riding, with equal parts uphill and downhill. Likewise, our Enduro Comp Shorts are designed to be true all-rounders on the trail, leaving you with plenty of comfort, performance features, and strength to tackle just about any trail.
To make sure of it, we made them from a woven version of our lightweight and ultra-breathable VaporRize fabrics. As a result, the shorts are more than tough enough to take repeated spills while you're finding your line (or losing it), without sacrificing anything to comfort.
In terms of fit, you'll find that these shorts fit nicely between our Atlas and Demo lines, meaning that they're certainly baggy but don't go over the top with it. As a result, we cut them to fall just around the bottom of the knee (about three inches shorter than the Demos) with plenty of room for light armor or kneepads. There are also side waist adjustment tabs that keep the waist where you want when the pockets are loaded. And for all-year riding, the Enduro Comp shorts have the added benefit of being treated to be water-repellant.
- VaporRize woven fabrics are treated to be water-repellant, while remaining durable, stretchy, and lightweight for peace of mind on the trail.
- Two zippered pockets provide convenient, secure space to store your trail essentials, while a SWAT access side zipper interfaces seamlessly with
- SWAT bib shorts for immediate access to your gear and nutrition.
- Side waist adjustment tabs ensure that the fit of the shorts is easily customizable and dialed-in, even when your pockets are loaded.
- Deflect UV 50+ protects your skin from harmful ultraviolet rays.
- 13.5" inseam (size 34 waist) fall low around the knee for a roomy fit that leaves plenty of room for pads.

This unmatched comfort comes, in part, from our custom, pre-molded 3D Chamois. Not only is it pre-molded to the shape of your body and saddle to reduce wrinkles and pressure points, but it also features multi-density foam that ensures the utmost in comfort. The other half of the comfort equation comes from the fabrics and the fit. For example, the welded uppers get rid of seams altogether for the most comfortable straps possible, while an articulated design ensures the perfect fit when in the riding position.
