The Tab Gear rear bag is an extremely versatile rear shooting bag which offers 3 different heights (flat, short side and long side). The fill is light weight and uses asymmetrically shaped beads that don't absorb water and due to the bead shape maintain their position much better than smooth round objects like beans or round plastic beads.
Each rear shooting bag has a strip of mil-spec webbing that runs the length of the bag. On one side the strap runs top to bottom while the other side runs left to right. This gives the shooter the ability to use the strap on the bag to assist in maintaining a less fatiguing hold on the bag in each of the positions. The corner of the bag has a loop for attaching a carbineer to make accessing the bag fast and easy - just clip it to your pack or a belt loop.
All in all the Tab Gear rear bag is a well thought out piece of kit.
