We've set the standard for lightweight insulation with Corey –and it's easy to see why it's still so popular. Constructed from high-quality, 100% recycled microfleece fabric, this half-zip fleece provides featherlight warmth in an instant, making it an essential mid layer all year round. You can trust Corey not to lose its looks, too – it stays soft, comfortable and bobble-free, wash after wash.
