The main story of this short is the use of our renowned top-of-the-line Progetto X2 Air Seamless seat pad in an otherwise traditional short, but in fact every little detail has been obsessed over to ensure your comfort on your next long endurance ride.

This short offers exceptional value and is ready to deliver lasting comfort on your longest rides. - Endurance Evolution fabric provides optimum muscle support and feels drier in nearly all conditions - Anatomic cut for perfect on-bike fit - Mesh bib straps and back to keep you cooler - Progetto X2 Air Seamless seat pad for even greater comfort and improved airflow - GIRO3 leg grippers lie flat

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

It's everything you need to comfortably enjoy dry winter rides. - Thermoflex fabric for warmth and comfort - KISS Air2 seat pad is so good it's the choice of some of our pro riders - Ankle zippers for easy on/off - Reflective logo below knee - Reflective flap over ankle zipper for extra visibility

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

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

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
