2.5″ FlexForm Belt FAQ

Do I need a belt size larger for extra layers during winter

No. Just measure around your belly button as demonstrated.

Can Diamondback Belts be used with other brand's tool belt pouches?

Yes. However, we can't promise the colors will always match. See how we do it.

Is the FlexForm belt as strong as a leather belt?


All Diamondback products are made with 1000 Denier(a measure of thickness) Nylon. 1000D Nylon has an abrasion resistance(the ability to resist wear) and tear strength greater than leather. See this chart :

[Materials] [Pounds of force until it tears] [Abrasion cycles on pavement until fabric fails]
Jeans 4.5 lbs 50 cycles
Leather 80-110 lbs 1200-1700 cycles
1000D Nylon 110 lbs 1780 cycles
*source High Performance Textiles and Their Applications

1000D nylon is so strong that it:
  • Was used in tires in World War II
  • Replaced leather in light combat boots for the US Army in the 1990s
  • Is used in high performance mountain climbing gear
