Hot and cold.
It's rare to see a garment touted for its ability to function in diametrically opposed conditions, but then not all companies are Giordana. Its Men's Short-Sleeve Ceramic Base Layer features futuristic fabric technology said to both reflect the sun's hot rays to keep you cool in warm weather and conversely trap in heat when the temperatures plummet to keep you insulated and warm in the cold.
The star behind this versatility is the Resistex Bioceramic fabric, 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. Capped off with streamlined, four-panel construction, this base layer is the perfect addition to nearly any day's kit.

Used this item 3 times this winter under a wind breaking long sleeve jersey in 40-55 degree weather riding for 90 minutes at a moderate pace and found it performed to my satisfaction. I would prefer to wear this in cool weather as it has the required loft and I feel it would be too warm for typical warmer weather.
