We've improved our All-Purpose rest top bag by making it from both high-quality garment weight leather and fine-grade, low friction Cordura. Use the soft leather side with talc or baby powder for wood stock and the Cordura side with bag wax or silicone spray for fiberglass and other synthetic material stocks.
Note: Sand required to fill all bags.
