LIGHT, DRY AND FAST Racing in the Alps in July is for a select few, but the products that come out of that experience are absolutely amazing for the rest of us. We made this jersey for the rigors of pro racing in hot weather and in the high mountains. It's extremely lightweight and features open fabrics for additional airflow and quick drying. And by using the same patterning as the Aero Race Jersey, we make sure you get maximum aerodynamics as well. Even if you don't race over the Galibier this summer, you'll love the soft stretch and great fit of this jersey, and you'll appreciate how it keeps you cool on the hottest days. Maybe you'll even do like the pro riders do and use it on wet days because it doesn't soak up any moisture. And you'll certainly appreciate that the fabric on the back blocks more than 90 percent of UV rays. - CFD-based fabric placement and seam construction - Engineered rapid cooling, light weight and aero efficiency - Flusso 3d fabric on front and side panels - Stradapro 3d back for breathability - Air mesh sleeves with raw-cut sleeve ending

The UMA GT Women’s Half Shorts set a new standard in on-the-bike comfort and female-specific design. The UMA GT Women’s Half Shorts blend several proven textiles and construction techniques to create a truly unique pair of shorts that are as fast as they are comfortable. Like our high-end Laalalai Shorts, they’re cut from Type.439 Diadema, a fabric chosen for its exceptional stretch, high-wicking, and compressive capabilities. Wind-tunnel tested and using our aerodynamic Fenomeno1 design, these are our some of our fastest women’s cycling shorts yet. The precise fit comes down to the waistband design, where we applied our breathable, ultrasoft Aerofit material at the front, using a fold-over construction that comfortably holds the shorts in place across the abdominals. We did the same at the lower legs, adding a secure, stay-put fit with an asymmetrical hold on the thighs. Compared to our Laalalai shorts, these are 2.5cm shorter in length. And in terms of the insert, we’ve sewn in the lightweight, breathable S7 EVO to deliver targeted support and all-day comfort.

The sleeves are lifted directly from Castelli's pro race jersey, but in this case because the four-way-stretch fabric with raw-cut sleeve endings is as comfortable as it is aerodynamic. The velocissima jersey is not lacking in technical details, but it was also designed to look good. The fabrics are piece-dyed for rich color, and then they get a sublimated overprint for the tone-on-tone graphic over the shoulders. It's finished with construction details like the three pockets that drop below the silicone waistband for easier access, while the easy-sliding ykk zipper makes ventilation adjustment easy. - Prosecco strada donna main body fabric for great moisture management - Velocity rev2 fabric for 4-way-stretch sleeves with raw-cut sleeve endings - Stretch-mesh side panels for better fit and breathability - Dyed fabrics for rich colors with sublimated overprint - Drop-pocket design for better placement of 3 rear pockets
