About Foam Weapons

There are essentially three parts for every foam weapon that you have to consider. The core provides structural integrity, the padding provides safety and the covering keeps it all in tact. Here are some general guidelines to follow when constructing foam weapons.

Core Flex guide


  • Allowed cores are: Fiberglass, Kitespar, Carbon fiber, Bamboo and Bandshoppe pole.
  • Cores may not whip at an angle of 45 degrees or more. See chart.
  • Wood or Metallic cores are not allowed.

Here are some general types of foam that can be used to build weapons.

  • EVA Foam, Polyethylene Foam = (puzzle mat, flip-flop, kneepads, padding in helmets) This foam comes in varying densities based on the weight of the foam per cubic foot (i.e. 4lb or 2lb)
  • Ensolite, marine foam=( yoga mat, knee cushions, boat cushions, life preservers) This foam is used in stabbing tips.
  • Camp pads This is the most common foam for people to find.
  • Pipe Insulation and Fun Noodle= Used for courtesy padding and throwies.
  • Open cell foam=( couch cushions, egg crate, Charcoal Firm Foam) Used in arrow tips and rocks.


  • All striking surfaces must be covered with cloth
  • Please refrain from using excessive layers of tape as it hardens the weapon and may cause injury.
  • Rule of thumb – 1 layer of strapping tape on striking surfaces covered with 1 layer of cloth.
