2-5 Ultralight Rear Bag
The Ultralight Rear Bag made from 500D Cordura only weighs 2.5 ounces (waxed canvas version weighs about 3.5 ounces). For comparison, Lobo's Garmin Tactix watch weighs 3.3 ounces. There is no reason not to keep this bag in your pack or with your range gear. With two handy straps, it will fill the space you need for a solid shot measuring 8 x 6 x 2.5 inches.
Straps allow the shooter to slide under a hand to gain complete control of the bag. The second strap is adjustable, giving the shooter the chance to tighten the bag for maximum adjustment of density and feel.
Backpack and back country hunters love the bag with virtually no weight penalty to make precision shots, and its versatility. The Ultralight Rear Bag gets used as a rest for binoculars/rangefinders, a comfortable pillow, cushion/protection in the pack, a seat cushion, and more.
See this video at this link to choose the fill density (amount of fill in the bag).

The Ultralight Rear Bags come filled with the best ultralight fill available. Unlike other bags with white foam beads that are easily crushed, and even in the heaviest of use, the special fill of the ultralight bag will never crush and will never loose volume.
