Hilleberg developed the unique Kerlon fabrics specially to provide extraordinary strength. They are coated on both sides, and have a total of three layers of 100% silicone. As a result, their strength-to-weight ratio is second to none in the industry, and they define not only the highest available standard in tear strength, but in waterproofness, as well. Kerlon fabrics are simply many times stronger that the majority of similar weight tent fabrics on the market today.
