The Castelli Endurance Women's Shorts are especially designed to ensure that, no matter how hard and far you cycle, you will feel great throughout your ride. To that end, they are built around a women’s specific version of Castelli’s most luxurious seat pad, the Progetto X² Air Donna seamless.Constructed with two densities of foam and gel pads strategically placed in accordance with the female anatomy to absorb vibrations and improve ride quality, not to mention a soft upper layer that moves with the skin, this pad offers optimal long-distance comfort. Your ride enjoyment be further enhanced by the excellent wicking abilities of the Endurance Evolution fabric, as will your stamina, since it is compressive and offers support to keep your muscles functioning beautifully. Meanwhile, the soft yet flat waist elastic, thoughtfully positioned hip seams and anatomic cut will ensure you can change position freely, even as the GIRO³ leg grippers hold the legs of the shorts gently yet firmly in place. Key Features:Women’s specific Progetto X² Air Donna seamless seat pad,Endurance Evolution fabric supports muscles and keep you dry,Anatomic cut for perfect on-bike fit,Forgiving, soft elastic waist, GIRO³ leg grippers.
We made this short to meet Castelli's high standards for comfort and performance in a cycling short while adding a few extra features that come in handy for riding on any surface. You'll find our normal exceptional fit as well as the KISS Air2 seat pad, which provides generous anatomically placed padding with an exceptionally soft top layer.What makes this short special is the extremely durable Unlimited Lycra® fabric. It has higher abrasion resistance and tear resistance while not compromising on stretch, moisture management or comfort.In addition, we use double-layer side panels for the old track rider's trick of fabric-sliding-on-fabric should you fall. This short isn't really meant to be indestructible, but it significantly increases the chances that sliding out on gravel will mean you need to just brush yourself off rather than having to buy a new pair of shorts.That second layer on the side panel also makes for convenient side pockets, with a flap over the top to prevent the contents from falling out.For added convenience while riding on and off road, you have two mesh pockets on the lower back that compress gear next to your body to keep it from bouncing around,This short adds durability and storage without compromising comfort — for unlimited amounts of fun.Key Features:Made for fast riding on unlimited terrain,200 g/m2 nylon/Lycra® fabric with best-in-class abrasion and tear resistance,2 mesh rear pockets built into mesh bib straps,Double-layer side panels reduce abrasion if you fall, while also creating 2 useful side pockets,Raw-cut leg ending with vertical silicone grip strips to hold leg in place,KISS Air2 seat pad for long-distance comfort,Weight:200 g.
The Right Race Jersey For Speed And ComfortSome triathletes choose long sleeves for the extra speed. Some for the comfort. Some for sun protection. This jersey gives you all three.The aerodynamic speed is unmatched. It's what Castelli does best. We have a year-round testing and development program with the Norwegian Technical University in Trondheim to make our race gear the slickest around.The comfort is what comes from our expert pattern engineers and soft performance Italian fabrics. We reduce the number of seams so that there is less chafing and less to bother you when you should be concentrating on pounding out the run.Sun protection ... well, you've trained untold hours for this day. We focus on speed, but we still manage to block 94% of UV rays with our back Velocity mesh fabric that doesn't compromise speed, comfort or breathability. You may want to add some sunscreen, but this fabric provides UPF 16 protection, which is a significant help. Your cotton T-shirt is probably UPF 8.Take note of the well-thought-out details: Castelli's generous two pockets lie flat but hold a lot of gear and nutrition. The SnapLock fasteners clip to Castelli shorts to prevent the top from riding up during the swim or bike.Key Features: 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 light 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 riding up during swim or bike leg, YKK® Camlock® zipper, Elbow-length sleeves for maximum aerodynamics.
