Hey thanks for you info mrbb, I don't mind paying the price for quality hunting gear if it does the job they claim it suppose to do, the scentlok vortex is a double layer of micro fleece with the wind proof lining between the fleece, I was told by scentlok that they have not used Gortex in their garments for quite sometime now because of the noise it makes when it does get cold. well time will tell how warm this new Vortex stuff is going to be, thanks again.
