Ultimate Sandbag Liners


Boost Up Your Older Model Ultimate Sandbags!

Our Ultimate Sandbag Training Liners are a great option if you want to still maximize your “older model” Ultimate Sandbags, but do not want to completely upgrade to our most current model. The small liner will fit our Core and Power Packages, the medium liners will fit our Strength Packages and the large liner will fit our Burly Packages. Please note our smaller liners are sold out, medium and large liners still available for Strength and Burly Packages.



  • Only one liner is needed per Ultimate Sandbag
  • Our Small Liner is SOLD OUT & will not be re stocked
  • Sand CAN NOT be poured directly into the liners
  • These liners will be placed inside the outer Ultimate Sandbag Shell then your fillers will simply go inside the liner to boost up your older USB models!
