Q & A


While all Castelli jerseys are designed to fit snugly; the Aero is designed to stick to your skin. It's a skinsuit of a jersey, saving you 10 watts compared to a normal jersey. That's almost a minute saved over 40km at 40kph. That kind of saving is a pretty heady promise. Thankfully, it is much more comfortable than a traditional skinsuit top, due mainly to the ultra-thin and very slippery Velocity fabric on front and combined with a mesh back panel. Velocity fabric is thin, light, breathes and stretches well. 

The jersey in your hand feels incredibly small. Your shoulder sockets and upper arms, when the jersey fits properly, seem to be bursting through the sleeves. The mesh panel takes in about half your back from mid-shoulder blades on down. The pockets are mesh as well. The arms have Giro++ grippers at the end, which is a thin single layer of stretchy fabric that holds onto your arm without silicone and without pinching. The grippers are flat, and quite naturally, fast. 

With this jersey, you can go two ways. One is to go with your normal size and the jersey will look like it's painted on. Or you can size up a bit and still have a super-light jersey that looks a bit more "normal" though slightly less aero. 

There are three pockets in back. The pockets are anchored by both the less-stretchy mesh back panel and the silicone gripper at the waist. The jersey zipper is 35cm in length, a size engineered to minimize drag. Like any ultra-engineered jersey, it might look a bit odd when you're standing up, but it looks perfect once you're on the bike. The Velocity fabric is treated with Prosecco to help improve wicking and speed up perspiration evaporation.
