Castelli Core Mesh 3 Sleeveless Mens Cycling Base Layer - White BackInStock-06-07-2026 DriLayer® Seal fabric delivers 14k/14k-ratedCreating that perfect summer weight base layer is harder than it sounds. We have intentionally made this product as minimalist as possible to let the open mesh fabric pull moisture off the skin. The secret to this base layer lies in the fabric that is highly stretchy but without Lycra, which tends to hold in the moisture. You stay drier and cooler.
