ForeFX Leather offers a comprehensive range of leather tempers engineered to meet specific performance and application requirements.

• Soft : Extremely soft and pliable. It does not tend to hold it's shape. Often used for garments or
  upholstery.
• Semi-Soft : Still very soft and pliable, but may tend to have a slight structure to it. Typically used in sneakers and handbags.
• Semi-Stiff : Stiff, but still soft, but not rigid. Tends to hold it's shape. Typically used in boots and motorcycle bags.
• Stiff : Has a hard and stiff feel and not easily bent or folded. Typically used for heavy duty belts, straps, or knife sheaths.
• Rigid : Rock solid and will not bend or flex at all. Typically over 10 OZ in thickness and used for body armor and horse tack.

The thickness of leather is measured in ounces. The weight can vary between sides due to natural variations in leather. Measurement typically takes place at specific locations on the hide—commonly the butt or shoulder region. The butt section generally represents the thickest portion of the hide, while the shoulder area is typically thinner (with exceptions in certain leathers like heavy harness). Some of our sides are leveled to provide a more consistent thickness.

One ounce of leather equals 0.4mm or 1/64 of an inch. Therefore, 9 ounces is equal to 3.6mm or 9/64 of an inch, and so on. Our conversion chart below provides a quick reference for various thicknesses. Please note that each piece of leather has a slightly variable thickness over the entire hide; our chart below reflects this variance.
