were is the cheapest place to purchase this product?

I haven't seen it widely available yet. Try Cabela's they have a pretty wide selection.

good luck trying to get this stuff i've been calling eders keystone country store and sportsmans guide since early july none have recieved any from arctic shield yet and they just keep moving the back order date back.they all have the socks in stock but no base layers i finally got fed up and ordered cabela's hunt series base layers they have the same X-static fibers that X-scent has
