When I tramp out into the woods here in Vt I carry the nylon GI camo poncho. It's not the color you may be looking for but it's pretty light weight. I like the one you highlighted except for the 10 inch neck zipper. I really carry the my poncho as a multi use item, tarp and rain gear. I do know that the nylon one is lighter than the one I think you are carrying.
