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-level comfort for every ride with Castelli's most comfortable seat pad. - Endurance Evolution fabric provides optimum muscle support and feels drier in nearly all conditions - Anatomic cut for perfect on-bike fit - Progetto X2 Air Seamless seat pad for even greater comfort and improved airflow - GIRO3 leg grippers lie flat - Weight: 186g

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 those days when you need to cover your knees but it's not quite cold enough for long tights, enter the Entrata Thermal Bibknicker. This no-nonsense tight simply uses our insanely soft, warm, and stretchy Thermoflex fabric for comfort along with our KISS Air2 seat pad, which is comfortable even over long rides and rough terrain. This is less is more" done right". - Thermoflex fabric for warmth and comfort - KISS Air2 seat pad is so good it's the choice of some of our pro riders - Mesh bib straps - Reflective logo below knee

It's an old trick to wear a great bibshort underneath a tight or bibtight without a seat pad to give two layers over the sensitive bits, and this tight lets you avoid having double straps over your shoulders. And if you're throwing some running into your training mix, you'll marvel at the warmth and comfort of this tight, while the reflective details will keep you visible. - Thermoflex fabric for warmth and comfort - Ankle zippers for easy on/off - Reflective logo below knee - Reflective flap over ankle zipper for extra visibility

The ultimate race short You know Castelli can make a great bike short. This one doesn't disappoint, thanks to amazing fit, the quick-drying instadry fabric that gives compressive muscle support, and the renowned kiss tri seat pad. New giro4 leg grippers hold the longer legs in place without riding up. For the swim we've made the short smoother through the water, and the back pocket will lie flat to avoid catching water. The snaplock closure clips to your Castelli top to keep it from riding up. On the run, the short basically disappears. The kiss tri seat pad is thin enough you don't really notice it. This short is so comfortable you'll be using it for training rides as well as racing. - Instadry speed fabric is fast in the swim with minimal water absorption - Free construction for great anatomic fit - Kiss tri seat pad is comfortable on the bike and virtually disappears on the run - Snaplock fastener at waist to clip jersey into place for swim and bike - Flat-lock stitching - GIRO4 leg gripper elastic for more comfort - Longer length for improved aerodynamics

A tri top has never been this comfortably fast Tri fashion (and the wind tunnel) have pushed toward short-sleeve tops, but we think there's still a place for the traditional sleeveless top. It's more comfortable on the run and cooler in hot weather. . . And maybe you're just a traditionalist. We've packed this top full of features: the front fabric comes straight from our Tour de France winning aero race jersey, and the back fabric offers maximum breathability. The top has two generous pockets for whatever you need to carry. It has snaplock fastners that clip on to Castelli shorts to prevent the top from riding up during the swim and to keep coverage of the lower back on the bike-then you unclip for added comfort during the run. The YKK zipper makes adjusting the ventilation easier than ever. Finally, we've taken extra care around the armhole to make it lie flat for speed yet remain soft to prevent chafing. - Freedom of movement in the water, aerodynamics on the bike, comfort on the run - Velocity rev2 aero fabric on front-facing surfaces - UPF 16 velocity mesh back blocks 94% of UV rays, with generous breathability - 2 rear pockets lie flat and prevent nutrition from bouncing around - Giro3 flat gripper elastic lies flat on lower back - SnapLock fastener at lower back to clip to Free Tri Short to prevent top from riding up during swim or bike leg - YKK® Camlock® zipper

Typically, our women's garments are designed from the ground up for women. However, the Free Aero 4 W Bibshort is designed from the ground up for racing. That specific goal leads us to a somewhat minimalist construction, but one that is made for aerodynamics and also comfort, since racing requires long hours in the saddle, both in training and on race day, resulting in one of our most comfortable shorts as well. The Free Aero 4 W Bibshort represents a significant evolution from last year's model, our best-selling short ever. 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 Sky 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 new Free Aero 4 W Bibshort also receives the updated Progetto X2 Air Seamless seat pad featuring the softest surface fabric you've ever felt in a seat pad. - Vortex dimpled fabric on legs for aero performance - Forza fabric on inner legs with 38% Lycra content for perfect fit - Stripe mesh engineered lie-flat bib strap construction keeps you cool - Giro4 leg gripper elastic for better grip distributed over larger area - Doppio V construction in front for increased comfort - Flat-lock stitching - Progetto X2 Air Seamless Donna women's-specific seat pad

The ideal tight for most of your winter riding, the Velocissimo is focused on comfort for riding in mild to cool conditions. We've used our Thermoflex fabric for most of the tight. It's not our warmest fabric, nor does it repel water like Nano Flex, but it is the softest, stretchiest winter tight fabric. The comfort is immediate and lasting. For the lower leg from just below the knee, we switch to our Nano Flex fleeced stretch-woven fabric that's both warm and highly water repellent for protection against spray coming off wet roads. It's also highly stretchy, and we leave a raw edge so we can construct the ankles without zippers while making sure the tight remains easy to put on and take off. The Kiss Air2 seat pad and mesh bibs keep your bum and upper body happy, while large reflective detailing keeps you visible. - Thermoflex fabric from knee to waist for warmth and comfort - Nano Flex stretch-woven fabric with brushed fleece inside at lower leg for splash protection from wet roads - KISS Air2 seat pad - Mesh bib straps - Zipperless ankle to reduce bulk inside shoe covers - Reflective inserts on thighs for visibility on back and sides
