Shorts/Bottoms

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.

Newton bib shorts are the go-to piece for long distance riding and racing in hot weather conditions. Soft and supple Titan PS fabric supports and stabilizes muscles and is so comfortable the short simply "disappears" under you. Technology: - Forma-Pro chamois features a multidirectional curvature that delivers a perfect fit for long duration saddle comfort. Features: - Premium high-gauge Titan PS Lycra gives a "barely there" feeling - Ergonomic multi-panel design contours with natural pedaling position - Mesh bib upper for heat dissipation - Wide microfiber leg bands lightly compress without restriction - High density chamois provide protection and pressure relief - Reflective accents improve low-light visibility to motorists - Flat seam construction - Fit=Fitted - UPF 40+

It Just Works Right Castelli has innovation in our DNA, and we've brought you most innovations in cycling shorts over the years: the first Lycra shorts on the market, the first synthetic seat pads, the first anatomical seat pads, the first minimalist and flat bib straps, and the first flat leg grippers. All these have become industry standards, and we keep pushing and innovating in our high-end shorts. The Entrata short is where we bring all that knowledge and experience into a short that just plain works. The fabric is just the right weight with just the right stretch and with a matte finish that looks just right. The KISS Air2 seat pad is just right, as is the GIRO3 leg gripper. And the short fits just right because we obsess over the fit of every short we make. We wanted this short to be just right for many years to come, so we stitch on the logos and stitch in the reflective panels on the back. There are no logos to peel off, and everything is stitched down securely. This short gives you every reason to step up to Castelli. - KISS Air2 seat pad for all-day comfort - Pro Dry matte Lycra for good compression and moisture management - 8-panel construction for perfect fit - Rear reflective panels on lower leg - GIRO3 engineered flat leg band - Mesh bib straps for comfort and breathability - 15°-35°C / 59°-95°F - Weight: 175g

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

When it comes to choosing the perfect pair of bib shorts, comfort is everything. And for anyone whose rides demand premium materials, superior fit, and cutting-edge technologies, the new RBX bib shorts are sure to be your jam. We designed an open suspender fit and bib construction that's engineered to keep the shorts up and in-place without constricting the upper body. The stretchy elastic suspenders are uber plush and soft against the skin, and accommodate taller torso lengths with ease. A non-stretch, sail cloth center back panel is laser-cut for breathability and anchors the back of the shorts for added stability. Silicone-infused fabric cuffs, meanwhile, provide a gentle, secure hold on the legs in order to ensure the perfect, shift-free fit. Our new Body Geometry Contour chamois also adds unrivaled comfort by minimizing its total footprint and keeping only what's structurally necessary. This minimizes pressure on nerves and soft tissue, while also maintaining the optimal level of support. - Soft and supportive four-way stretch fabric provides ample comfort and a soft hand. - Soft mesh bib uppers with binding provide a comfortable hold. - Silicone-infused fabric cuff provides a gentle, secure hold on the legs in order to ensure the perfect, shift-free fit. - Articulated design ensures the perfect fit while in the riding position. - Reflective elements increase your visibility to motorists in low-light conditions. - UPF 50+ rating protects your skin from harmful ultraviolet rays. - Single-density-foam Body Geometry Contour Chamois is pre-molded to match the shape of the body for exceptional comfort. - Slim Fit with a 10.5" inseam.
