Homeostatic.

As with virtually everything it produces in its Italian factory, Giordana engineers the Ceramic Short Sleeve Women's Base Layer with levels of tech we don't typically see anywhere else in the industry. It's got the usual base layer qualities—a four panel body that maintains a slim fit—but the material pushes it into a realm beyond what we'd expect. Well, beyond what we'd expect from any brand not bearing the Giordana centaur logo on its chest.

Giordana's penchant for going above and beyond manifests in the Resistex Bioceramic, which is a synthetic microfiber blend that's fused with mineral bio-ceramic crystals. Giordana claims these crystals actually reflect external heat while working to maintain body temperatures. The result is that the material actively works to maintain thermal homeostasis, keeping your body in its comfort zone whether the weather is hot or cold or somewhere pleasantly in between.

• A versatile cycling base layer for use in most conditions
• Material blend maintains body temperature in hot and cold
• Four panel construction reduces bulk with a slim fit
