Triple Tanned- A combination of three different tannages are used to create a full-grain leather that is resistant to chemicals, alkali, acids and enzymes. Conventional leathers only use one tannage. Water resistant- After being triple-tanned and dyed SPR leather is impregnated with a special formula of waxes and oils that are not soluble in water. This process makes SPR leather extremely high water-resistant. It can also withstand repeated wettings and forced dryings (on a heat duct or radiator) without shrinking, cracking or losing its rich oily feel. Sweat Resistant- Independent laboratory test confirm that SPR leather will not shrink or lose its shape, even after extended exposure to perspiration. 3 Times Stronger- The combination of triple tanning and oil impregnation make SPR leather three times stronger than comparable leathers. 2 1/2 times more abrasion resistant- Laboratory tested found SPR leather to be 2 1/2 times longer lasting than conventional leather. Barnyard Proof- In every test performed, SPR leather proved to have remarkable resistance to or no ill effects from the most severe chemicals found in any workplace, including organic and inorganic acids, alkali, chemicals, urea, lactic acid, manure, salt and enzymes normally associated with farm or ranch environments.
