The Castelli Presto Due Bib Short offers breathability, moisture management, slight compression, and Castelli's bacteriostatic chamois pad, the KISS3–all for less than a decent helmet, a low-end jersey, or a pair of bargain cycling shoes.
For the construction, Castelli made the Presto Due from its Affinity Lycra fabric. This material features the hold and support that we know from Lycra, however, Affinity provides more stretch and elasticity than many other Lycra iterations. You'll also find that the material is incredibly light and soft–190 gram fabric weight, actually. This converts to around 140 denier, which, in the real world, translates to a slightly compressive fit and high thread count per centimeter. So, this means that your muscles will be protected from the fatigue-causing effects of road vibration and oscillation. But, why is the high thread count important? In a word, abrasion. By compacting the threads, Affinity becomes less course, lighter weight, and more gentle on the skin. Additionally, the fabric has been designed to be an effective moisture manager. So, during long, hard exertions, Affinity will pull moisture from the skin and transport it to the material's quick-drying surface.the bib portion was also designed with hot-weather cycling in mind. Castelli used highly breathable synthetic open mesh to provide fit, structure, and security without hindering breathability or moisture management.
In terms of fit, Castelli designed the Presto Due bib shorts around the cycling position. Essentially, this means that the multi-paneled pattern has been cut on a contour–you'll notice this when the shorts are hanging. So, the shorts' anatomic design allows for a full-range of movement without the risk of fabric pinching, bunching, or chafing. The bib follows this design concept, as well, with a fit designed for the crouched pedal position.
And extending the Presto's range of comfort, Castelli included its venerable KISS3 chamois. For a point of reference, Castelli only makes two road inserts, the Progetto X and the KISS3. So, it's evident that this chamois receives Castelli's unwavering vote of confidence. This is further reinforced by Castelli engineering-in many of the Progetto's key traits, only at more cost-effective price. Starting at the surface, the KISS3 uses a skin-care layer comprised of a bacteriostatic fabric that conforms to the body without folding. The material supports airflow, and aids in evaporation. The second layer is multi-density foam with continuously variable thickness where you need it, not where you don't. So where is it placed? Well, Castelli made sure to maximize thickness at the highly-sensitive ishial and to moderate thickness at the perineum pressure regions. Additionally, the insert has a minimal density along the perimeter. This translates directly to insert flexibility, so, you won't experience any uncomfortable riding or pinching.
The Castelli Presto Due Bib Shorts are available in six sizes from Small to XXX-Large and in the colors Black/white, Red/white/black, Anthracite/white, White/ocean/black, and White/anthracite/black.
This a great bib for the sale price - clearly a step up in materials and design from the ergo tre. The only problem is in the blue model I had to go up to XXL to get a comfortable fit because the straps are so tight. On all other Castelli bibs XL fits fine. I wonder if the other colors are so tight because they are not so discounted?
I'm 5'7" and 165 lbs. Ordered the L and XL as a comparasion. The L fits pretty nicely. I have an issue with the quality of the lycra. Feels thin and the stiching does not feel sturdy. But the bibs are pretty cheap. I ended up returning and purchasing the de marchi bibs ( slighty more expensive @ 80, but the quality feels much better ).
I love the style and choices of colors. I didn't read the review and they are correct on the sizing. I wear a small but the small on these is for someone really short. The bottom fit nice, but I couldn't put the straps on. Way to short and I'm only 5'7". Will be ordering a medium and hope they will fit.
They run about 2x too small, good value for a $60 Castelli bib, nice looking. Time will tell if they last.
