Bison Tactical Dual Fill System

The new dual fill system from Bison Tactical is the perfect way for any shooter to reduce the weight of the gear they carry.

When installed in the Fat Boy Tactical Udder, the dual fill system reduces the overall weight of the bag by nearly 2.5 pounds. The best part about the dual fill system is that it doesn’t just work with the Tactical Udder – it’s compatible with any bag!

The dual fill system comes in two different sizes to ensure that you can find a good fit for whatever bag you have.

This one is 8″ x 8″ x 2″ with a weight of only 1.5 ounces in total.

The other “Dual Fill System 7.5X5″ is 7.5″ x 5″ x 2” and weighs a total of 1 ounces.

The larger square size is designed to fit perfectly into your Tactical Udder or other large bags, while the narrower size is meant for use in bags like the Armageddon Gear Reason Gamechanger that can’t otherwise fit the square option.

Made from a durable nylon, these fill bags will stand up to the test of time while maintaining the minimum weight possible.

Refer to the video below for Instructions on how to use the Dual Fill System with the Fat Boy Tactical Udder:

Remember to re-install the aluminum stays after closing the udder with dual-fill inside.

A zipper for fill adjustment is included in the dual-fill system bag, but it’s highly recommended that you adjust fill in a high humidity environment to reduce mess.

An easy way to create a high humidity environment is to run a hot shower for 5 min in your bathroom, and adjust the fill while the humidity is high. Plastic containers are to be avoided when storing excess fill, as they increase static. Instead use cardboard or paper for best effect.

If you find that the dual-fill system does not have enough fill after installation, you can use a funnel (rolling an 8×11 printer paper can work for this) to restore fill. In order to have this capability, make sure you install the dual-fill with zipper facing the velcro opening of the udder, otherwise it will be inaccessible.

Happy shooting!
