Description
Castelli Pro Mesh 2.0 Sleeveless Base Layer
A barely there, pro level base layer built for warm weather riding, the Castelli Pro Mesh 2.0 Sleeveless Base Layer is the lightweight evolution of Castelli’s Tour de France-winning design. Made entirely from airy 3D mesh, it excels at pulling moisture away from the skin to keep you cool, dry, and comfortable in everything from mild spring days to peak summer heat. It stays invisible under your kit thanks to its flat hem – but once the jersey comes off, the bold sublimated print shows you’re wearing something special.
Key Features
- 3D mesh fabric for excellent moisture management
- Sublimated print graphic
- Flat waist hem that stays invisible under shorts
- Castelli comfort rating: 15-32°C
Cooling Performance for Hot Conditions
The open 3D mesh structure promotes constant airflow and rapid moisture dispersal, helping regulate body temperature when the pace rises or the day heats up. It’s the sleeveless version preferred by Castelli’s pros for warm weather racing and training.
Smooth, Unobtrusive Fit
A low profile, flat hem ensures the base layer sits cleanly under shorts and jerseys without bunching or showing through. The sleeveless cut makes it ideal under both sleeveless and short sleeve jerseys, adding comfort without adding bulk.
Style Beneath the Jersey
While it stays hidden during the ride, the all over sublimated print adds personality when you unzip or remove your jersey. It’s a subtle nod to pro level kit with a bit of flair.
Proven by the Pros
Developed with Castelli’s WorldTour athletes, this base layer is built for versatility. It’s designed to keep you dry in mild to very warm conditions – and can even be paired under a Flanders Warm layer when temperatures drop.
