Performance Fill Options
Personalize your support bag with three distinct fill options designed to meet your specific needs.
WHICH FILL IS BEST FOR ME?
The right fill can make the difference between a bag that you rest your rifle onto and one that truly locks you into position. That’s why we offer multiple Performance Support Bag Fill options, allowing you to tune weight, stability, and responsiveness to match your shooting style.
Whether you’re a competitive shooter, an avid hunter, or a casual gun hobbyist, selecting the right fill will ensure your support bag performs exactly as you need it to.
UltraLiteFill
Ideal for backcountry hunters, varmint and predator shooters, and ruck-style competitions, our lightest fill utilizes expanded polypropylene to achieve minimal weight. Each bead is closed-cell, so water does not absorb.

Its lightweight may affect the stability of your position.
CoreFill
Our classic polypropylene fill delivers the ideal balance of weight and flexibility—staying secure while conforming to any surface. Each bead is closed-cell, so water does not absorb.

FAQ
No. The bag’s external dimensions remain the same. Fill options change the weight and density, which affects how firmly the bag settles on barricades or terrain.
Yes. All of our support bags feature a secure hook-and-loop access point so you can adjust your bag’s fill to your preferences. You can also order 1lb bags of our performance fills if you ever want to test out a different option.
Most PRS shooters choose CoreFill or CompFill because they provide the stability needed for barricade stages and positional shooting.
UltraLiteFill is the most popular option for hunting and field matches because it reduces the weight you carry while still providing reliable support.
Since Performance Fill bags are built to order, selecting a custom fill may slightly affect production time depending on current order volume.
