Castelli Core Mesh 2026 Short-Sleeve Base Layer

Shirt that you forget about and regulates sweat very well, I do not regret my purchase. Fits small, do not hesitate to take a size up. (Translated review)

Once on, you don't feel it anymore, it is light and breathable (Translated review)

Very qualitative product. Be careful, Castelli runs small. (Translated review)

Be careful as usual with Italians (Castelli), size S/M is closer to S, so for size M take an L. Otherwise, the material is pleasant to wear and easy to maintain, ideal as a base layer in very hot weather. Richard. (Translated review)

Jersey that allows regulating perspiration - very comfortable - (Translated review)

This undershirt regulates sweat very well, causes no irritation, and is completely forgotten during hours of wear. If properly maintained, it's an investment that is as effective as it is durable. (Translated review)

Light but very effective...keeps the body dry. Useful for temperatures between 17 and 20 degrees. Very easy to maintain as it dries very quickly and retains its color (Translated review)

This underlayer is perfect and avoids friction with the jersey. I recommend it. (Translated review)

Light and airy, prominent size (Translated review)

Provides a layer avoiding direct contact with the jersey. Comfortable to wear, lightweight. Very fragile, the first one received was torn and expensive for what it is if bought at full price! (Translated review)
