We measure WeatherMAX cracking resistance by folding the fabric on itself and putting it in a deep freezer at -45°F for 5 days. It is then removed, unfolded and inspected for any cracks or breakdown at the fold. After such difficult testing as mentioned above, many coated fabrics will show cracks and discoloration of the coating, whereas WeatherMAX remains unchanged. Also, some coated materials are degraded by saltwater, however, WeatherMAX has been proven to be unaffected.
