When the trail is rowdy, rough, and throwing everything including the kitchen sink at you, the Rampage Pro Carbon MIPS™ Helmet puts you in a ‘gimmie more sink’ mood. This kind of confidence can only come from absolute trust in your helmet, and that’s what you get with the Rampage Pro Carbon. This is performance and protection wrapped in one lightweight, race-ready package. Trusted by UCI World Cup Champions—and designed with direct input from Fox's elite downhill and freeride athletes—its features read like a gold-standard helmet checklist. MIPS™, designed to reduce rotational motion and redirect forces from your brain in a crash, is top of that list. Pair that peace of mind with breakaway visor screws that are designed specifically to sheer off on impact and reduce those rotational forces, and that’s protection dialed. There’s no need to sacrifice comfort or performance for that protection either. Dual-density, injection-molded Varizorb™ EPS liner balances of weight with performance, but also ups the protection further by spreading forces over a wider surface area. Superior ventilation and airflow come care of the injected mesh vent screens, keeping you cool while also protecting against flying dirt and debris, while the X-Static® head liner and cheek pads ward off bacterial growth (meaning less of your stink gets into it), and is machine washable. - Proven MIPS™ impact protection system reduces rotational forces in a crash - Breakaway visor screws sheer off at impact - Dual-density, in-mold Varizorb™ EPS balances weight with performance - Lightweight, carbon fiber shell - Injected mesh vent screens provide ventilation and airflow, and shield from dirt and debris - Moisture-wicking, antimicrobial, washable X-Static® comfort liner and cheek pads

The performance tight with the right weight for most winter riding, with a focus on comfort, stretch, and protection. - Nano Flex 3G fabric from waist to knee for soft warmth with maximum stretch and water repellency - Nano Flex stretch woven fabric with brushed fleece inside at lower leg for splash protection on wet roads - Stretchy bottom of leg with raw-cut edge means ankle zipper is not necessary - Minimalist bib straps, as found on the Free Aero RC Bibshort, don't add extra bulk - Rear pocket at bottom of bib straps - Reflective tabs on back of legs - Progetto X2 Air Seamless seat pad for long hours in the saddle

This short is the result of decades spent working to make long hours in the saddle ever more comfortable. The fabric is our high-stretch Forza fabric. The 38% Lycra content means that it’s gently compressive while never binding. And it maintains an insanely soft hand. The nearly seamless construction is derived from our Body Paint shorts, which debuted a decade ago and started the trend of reduced seams while maintaining remarkable fit. Nothing to rub or break. The renowned Progetto X2 Air Seamless seat pad gets an update in this season with a new skin care layer that features a remarkably soft new surface fabric and more stretch, which allows us to eliminate the front triangle. We also obsessed over every other little detail, like the new bib construction and even new silicone logos that stretch with the base fabric and recall the logo location of the first Castelli Aero Short from the late ’70s, the short that started it all. - Forza fabric with 38% Lycra content for a perfect fit - Dual-layer lumbar support band keeps shorts locked in place around waist - Reduced seaming for more comfort - Raw-edge leg ending with vertical silicone grippers - Mesh back with bonded 2-layer bib straps - Silicone Castelli logos - Progetto X2 Air Seamless seat pad

The Premio Bibshort has been engineered to provide the ultimate in long-distance comfort and to be your favorite bibshort ever. That's a big claim, but there's a lot of development in this short to back it up. So let's take a tour of the short. The first thing you might notice is what's missing: the seams and multiple panels. We engineered a new fabric that changes depending on the needs over various parts of the body. The lower leg has a raw-cut leg ending and rubberized yarns to guarantee a flat grip to keep the leg in place. The fabric becomes lighter in the thigh, while the four-way stretch provides just the right amount of muscle support. In the pelvis area, the compression and support increase to keep the seat pad and everything else in place, and the fabric gets thicker to avoid any embarrassing transparency issues. With this magical fabric we don't need to stitch separate panels together, which ensures more comfort and a better fit, as well as a sleek, sophisticated look. The premium fabrics extend into the bib straps. The perforated back keeps you cool and the edge is bonded so you don't feel the thickness of a stitched edge. The elastic straps have just enough modulus (return) to hold your shorts securely in place without cutting in to your shoulders. The seat pad is our top-of-the-line Progetto X2 Air Seamless pad. It's actually two separate components: a soft, stretchy Skin Care Layer next to your skin, which has the sole purpose of preventing any rubbing on your skin, and, under that, the Cushioning Layer, which features two separate densities of foam along with breathable perforated gel inserts under the ischia bones and perineum. We've carried the less-is-more theme into the design, with minimalist laser-etched logos and subtle finishing. It looks as premium as it feels. You can tell that every component, every stitch, every detail has been obsessed over. You'll not find a better bibshort. - The premium all-conditions short - Gradient stretch woven fabric for the right support in the right place - Woven fabric weighs 30% less than comparable knit fabric - Perforated back bib panel with lie flat bib straps that don't bind at shoulders - Integrated gripper elastic at leg ending holds short in place without need for extra silicone grippers - Laser-etched logos with RossoCorsa at center back and black scorpion shadow logos at lower legs - Progetto X2 Air Seamless seat pad

Engineered to be the convergence of speed, comfort, and style. - Stretch woven lightweight body fabric in recycled microfiber polyester for excellent moisture management and 26% elastane for stretch - Main body fabric rated at UPF 50+ for maximum sun protection - Shoulder panel in recycled ribbed stretch woven mesh to keep you cool and comfortable while adding world-class aerodynamics - Collarless construction makes it feel lighter and cooler - Reverse-coil self-locking YKK® zipper with U-shaped zipper pull for easy adjustment - Silicone gripper elastic on back with no-sew bonded front elastic panel

Rain jacket

The Raddoppia 3 Jacket is clearly designed to hit all the prerequisites for winter riding without added complications: windproof, warmly insulated, water repellent, breathable, and with 360° reflectivity, along with Castelli's functional attention to detail and fit. - Warm and reflective, the ideal winter cycling jacket - GORE-TEX INFINIUM™ WINDSTOPPER® X-Fast fabric with fleece backing for warmth - GORE-TEX INFINIUM™ WINDSTOPPER® 150 lighter-weight side panels and sleeve inserts for extra stretch and ventilation - Large reflective stripes on chest and rear pocket - YKK® Vislon® zipper for easy-sliding ventilation adjustment while riding - 3 rear pockets with 4th zippered key/money pocket - Drop-tail panel for extra protection from wheel spray

Light, Cool and Straight Out of the Future We've been pushing the envelope on lightweight shorts since 2011 but have butted up against the limits of compromising durability for ever lighter weight. We needed to step back and find a better way. We examined what the short really needs to do: it needs to hold the seat pad securely in place while otherwise adding as little weight or fabric as absolutely necessary (without being transparent, obviously), and it needs to last a season of hard use. So we engineered a brand-new fabric using a woven, rather than knit, construction that shaves 30% in weight for the same level of support and non-transparency. Then we worked with the world's leading mill to construct a gradient fabric that becomes increasingly lighter the farther down the leg it extends, with the last part weighing a mere 90 g/m2 compared to normal short fabric, which weighs around 220 g/m2. This fabric, while being insanely light, maintains a decent durability along with excellent abrasion resistance, at least against the saddle. We don't guarantee it against unplanned slides across the asphalt, so please keep the rubber side down! Note that while the short saves a mere 48 grams while dry, this means it also absorbs around 30% less moisture when you're sweating. So when you're sweating your way up the Alpe d'Huez you're actually saving closer to 150 grams. This short doesn't compromise on comfort. We use our top Progetto X2 Air Seamless seat pad, the spectacular striped mesh bibs from the Free Aero Race 4 Bibshort and a flat stretch woven leg gripper to keep everything in place. - The premium lightweight hot weather short - Gradient stretch woven fabric for minimal weight with optimum support - Ultralight fabric to reduce weight by up to 50% while improving durability - Minimalist stripe mesh bib to minimize weight and keep you cool - Integrated gripper elastic with exposed Lycra to hold leg in place - Embossed logos and stretch silicone scorpion heat transfers - Progetto X2 Air Seamless seat pad

Even though the temperatures start to drop in the fall, that doesn’t mean you should stop heading out on gravel adventures. The Unlimited Trail Bibtight offers exceptional rain and wind protection with tons of extra storage. To make sure you can be comfortable even on the longest gravel rides, we use our Nano Flex 3G fabric: warm, stretchy, luxuriously soft, and highly breathable, and on top of that it features our proprietary third-generation nanotechnology water-repellent finish. The Progetto X2 Air Seamless seat pad will also make sure you stay comfortable over long distances or rough roads. Two cargo-style pockets allow for plenty of extra storage, with security flaps to make sure you don’t lose anything, especially on rocky roads. To keep you from overheating, the bib straps are a stretchy mesh that not only helps regulate temperature but also ensures a great fit. The tight is completed with zippered ankle closures for easy on and off and reflective details for added visibility. - Nano Flex 3G fabric is exceptionally warm and soft with great rain protection - 2 cargo-style side pockets with flaps over top to keep stuff from falling out - Reduced seaming for improved comfort and fit - Mesh bib straps don’t hold moisture and allow for maximum breathability - Progetto X2 Air Seamless pad for long-distance comfort - Reflective details on back of leg with ankle zip closure for easy on and off
