If you're looking to upgrade your accuracy at the range, having a good rest is a must! I've crafted these unique, and durable bags from elk leather, and filled them with sand. All of the seams have been gone over 4 times with heavy duty appolstery thread, and the tops hand stitched 4 times with heavy artificial sinew. These are a game changer if you're used to using wood blocks, or a pillow/ balled up jacket as a rest for shooting. Each one is unique to itself as far as firmness/size. And I can also custom make them to fit your needs if requested. $75 each. Price is firm.
