95% of my hunting is done with Cabelas Silent Weave in 2XL so I can fit any amount of warm clothes under it. Silent Weave is very cheap, almost burr free, and it's pretty tough, yet very very quiet.
I have other camo (MT50 whitetail extreme), but it is much louder especially when walking through brush.
Easiest way to test it in a store, zip your fingernail along the fabric.
