I have decided to buy some Sitka gear but I'm have a hard time find any specs on it. I will be using it for stand hunting whitetail deer. I have plenty of heavy weight stuff. I'm looking for pants -bibs and a jacket -coat. 20-40 temp range. Already have good base layers. Looking for waterproof -water resistant and wind proof. Quiet material is very import!!! And info would be greatly appreciated. What do I need to buy ?!
