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. A great pad is useless without great fit. The seams are placed around the hip area to create a perfect shape on the bike. The Endurance Evolution fabric has a soft hand while providing good compression and excellent moisture management. And it's all held in place with the amazingly comfortable GIRO3 leg gripper. 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

For 2019 we've made some dramatic changes. Not because Team Ineos or you were asking for it, but because we've been riding in it a ton and thinking constantly about how we could make it better. There's a new leg gripper that still features a lie-flat raw-cut edge but now has vertical silicone stripes to keep it in place without restricting stretch. The new fabric allows for better print quality for your custom team production, the same as Team Ineos will use in 2019. We've updated the seams to improve the fit and make the short look even better on the body. We've re-engineered the bib straps with new fabrics and construction so they stay cooler, lie flatter and are more durable. The revised Free 3 Aero Race Bibshort also receives the updated Progetto X2 Air seamless seat pad featuring the softest surface fabric you've ever felt in a seat pad. You'll be glad we ignore the old saying, If it ain't broke, don't fix it. - Vortex dimpled fabric on legs for aero performance - Forza fabric on inner legs with 38% Lycra content for perfect fit - Stripe mesh engineered minimalist bib construction keeps you cool - Giro4 leg gripper elastic for better grip distributed over larger area - Doppio V construction in front for increased support and comfort - Flat-lock stitching - 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

The Sorpasso Bibtight is our best winter tight because of its exceptionally wide comfort range and the amazing fit. And both of these features come from the combination of our Thermoflex Core2 fabric and our standard fleecy Themoflex. The Core2 fabric is made with a hollow-core polyester yarn on the inside and a nylon outer face, which together provide excellent insulation for cold temperatures along with better wicking to keep you comfortable when it’s not so cold. This fabric offers some wind protection but is somewhat limited in stretch, and that’s where the extremely stretchy Thermoflex fabric comes in. The overall effect is a tight that offers optimal compression and seems to just move with you. - Our best-fitting tight for a wide range of cool to cold conditions - Thermoflex Core2 front and knees for extra warmth - Thermoflex over thighs and back of legs for extra stretch - Castelli shadow wordmark in colored leg band - 3D support band at lower back and flat bib straps for extra comfort - Progetto X2 Air seat pad for long-distance rides
