The PowerAir Zip is a non-fleece option zip up. PowerAir works by retaining heat in little pockets in the fabric with a more tightly woven outer layer.  This fabric stretches with you, blocks the wind, and packs some heat!
 
This Zip up is more durable than your typical fleece, but retains all the benifits of a stretch fabric. This layer is more comparable to a softshell jacket than it is to a fleece.
This full zip comes with two hand pockets, and a zip up chest pocket.
