Layering is the key to staying comfortable in inclement weather, and we believe that doing it right is an art. This doesn't mean that you need to increase the volume to retain as much heat as possible but rather use smart and breathable parts from the bottom up such as the Essential Layer Vest from POC. The Essential Layer Vest provides a snug fit with flexible side panels and lightweight fabric , which provides first-class breathability and moisture wicking keeping you dry and warm. Lightweight fabric ideal for cycling because it improves moisture removal without increasing volume preventing the inside from overheating while wicking away sweat. The vest fits snugly to the skin and fits comfortably under the jersey , providing additional comfort when freezing temperatures challenge your desire to ride.
