Castelli's Core Mesh Baselayer is specifically designed for warm to downright hot riding conditions, working to boost moisture regulation beneath your jersey.

This is made possible thanks to a fully open mesh fabric and body wrapping fit which offers exceptional wicking, creating a layer of air between your skin and jersey. Minimal seams ensure comfort and the extra long cut makes it easy to tuck into your shorts.

The Core Mesh Sleeveless Baselayer is available in White.

Fit note: This garment is very stretchy and designed for a form fit, we recommend purchasing whichever baselayer size includes your typical Castelli jersey size (e.g. if you wear a Medium Jersey, choose the S/M size baselayer). Consult the sizing chart for Castelli Jersey fit.

Note: Castelli tops and bottoms are designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.

I'm a big fan of Castelli base layers. They just work. Only gripe here is the neck is a bit too snug.

Like other Castelli products I've purchased, this is well made and well designed. My experience with CAstelli base layers is great - I wear one on any ride. As noted, my only issue is the neck hole is a bit too snug - and I don't have large neck.

Nice base layer for hot summer riding

Wash on delicate cycle and works as intended to cool you off on the ride.

Good for wearing under jersey a little tight on neck

The base layer is comfortable and provides breath ability and also a cotton layer between my heart monitor and the jersey

One nit to pick...

Castelli's mesh works better wicking sweat than any other hot weather base layer I've tried. It's also super-soft, unlike some others that feel like basketweave. Fit and finish are excellent.

The one thing I don't like, though, is the tight-fitting solid fabric neck, which extends several inches down (to include the Castelli logo?). It seems constricting and hot when I first put on this layer, although once I'm riding I forget about it so perhaps it's not functionally significant.

The 4-star value rating is for a discount price at BikeTiresDirect-it only rates 2 1/2 stars at full price.

This was a good item for the price.

For a Castelli the fit was not quite to par, somewhat loose fitting in some areas like its stretched out.

Nice, but the neck is too tight.

Good wicking properties, but the neck is tight. I followed the guidelines for fit and everything was a good fit except for the neck which was small. I am hoping the neck will stretch out a little more, with wear.

Very Nice

I've owend quite a few lightweight base layers over the years, and this is easily one of the best. The fit is great and the wicking away of moisture is phenomenal. Well worth it. When you initially put this on the nexck will seem really snug, but shortly after you don't even notice it. On those cool mornings... it's kinda nice.

Castelli Small - thin material

I have been looking for a good quality summer baselayer shirt. I was very disappointed how thin the material was and thought it would be destroyed even after a few washes even on delicate.

Works well - neck too tight

Initially, I took this on a 10 day cycle tour. I wore it with a variety of jerseys, both merino wool and synthetic. Being from Alaska, I do not tolerate heat well. I still got ht while riding in temps 30C, in both the wool and synthetic jerseys. As with no baselayer, the baselayer did allow bees that got drawn into my jersey to sting me. The one thing I found uncomfortable was that the neck opening made me want to stretch it out. I have a medium baselayer and my neck size is 15.5 Stretching it out helped a bit, but I still found myself grabbing it and stretching it more from time to time. Since returning to Alaska after the tour, I've worn this under my jerseys in cooler temps. It does help to maintain a comfortable temp and the jersey zipper allows me to regulate the temp well.

You got to give this garment a try

I have traditionally worn a winter base layer, and was intrigued with the thought of wearing a base layer in the hot summer months here in Texas. I purchased this garment, and have worn in on hundred degree days, could not be more pleased. It wicks away moisture in addition to providing insulation from a wet soggy jersey. The garment is light weight, and very well made. The only possible negative is the high front neck, which fits kind of snug. But this is being very picky as it is easy to get used to. Overall this is a great investment, and wonderful summer addition to your ride.
