CORE 2 SHORT
Perfect for runs, and short-distance tri events, these shorts are crafted from Pace 3 material that supports your muscles with gentle compression, and offers fast-drying properties to keep you fresh, even after a dip in a lake. Pace 3 loads you up with a high lycra content, giving it a ton of stretch to conform to your body and keep the fit as aerodynamic as possible. Lie-flat GIRO3 elastic keeps the short firmly in place regardless of what discipline you currently find yourself in.

- Stretch short for run training and short-distance races
- Pace 3 Lycra® fabric
- Lie-flat GIRO3 elastic
- 1 rear pocket
- Liner without padding for running comfort
Castelli forgoes any sort of padding or chamois preventing the absorption of water during the swim and reducing any kind of bulk that would interfere with the run. And since you probably don't have pockets on your singlet, you'll appreciate the Core shorts' rear envelope pocket giving a bit more room for easily-accessible food, letting you abstain from strapping baguettes to your top tube for mid-ride carb loading.

Muscle Support and Speed
In re-engineering the Free we took a look at blood flow, providing just the right muscle support without constricting. The revolutionary Giro Air leg band provides more stretch and distributes the compression over a larger area. The body of the short uses 30% Lycra® for excellent return.
We also looked at aerodynamics, optimizing boundary-layer airflow with the Giro Air leg band and the dimples on the side fabric. The wind tunnel says it saves 10 watts at 50 km/h, but you’ll probably want to go even faster because your aero advantage will only increase.
Confort and Fit
The best race short must be supremely comfortable. The new fabrics are all softer than the outgoing fabrics, especially the new softer surface fabric on the updated Progetto X2 Air seatpad. The innovative double V construction on the front keeps everything in place without compressing your stomach. And we’ve engineered a new Carré yoke that makes the straps lie perfectly flat.
But the most important part of comfort is fit. As one of our pro testers said, “These shorts fit perfectly. They don’t move around. Everything is just right.”
The Castelli Core 2 Short - Black destined to impress, and priced at only $39.90, for a limited time.
