Castelli - AR 4.1 FZ
Being aero is one thing, and make no mistake, the Free AR 4.1 Jersey FZ is very slippery through the air, saving approximately 12 watts at 40 km/h compared to a standard jersey, but without comfort, you'll never feel able to truly push at your hardest. What started as a pure race-focused jersey, the Aero Race 4.0, Castelli have steered in a new direction with the 4.1 jerseys to focus as much on your comfort and with convenience features not usually found on a pro-only race jersey. Velocity dimpled fabric on front and shoulders is aerodynamic, but also remarkably breathable for ideal summer coolness, while Nervato fabric at the armholes also contributes to reducing drag. This jersey certainly won't hold you back.
Stretch materials and a more generous race fit mean us 'normal' riders can enjoy perfect mobility on the bike, while a flap behind the zipper protects your neck from rubbing, making the jersey incredibly comfortable. Angled rear pockets make access to nutrition and spares wonderfully easy and a zippered rear pocket gives safe storage space for keys and coins. Reflective details are also added, enhancing visibility when you're out after dark on a balmy summer night ride. This would all be superfluous on a normal aero jersey but here it all adds up to a jersey you can easily race in but at the same time is perfect on your Sunday group ride. A jersey for all your biking escapades.
