Denim might be the most iconic fabric known to man, but even the strongest cuts don't stand up to the wear and tear you encounter as a biker. Saint Unbreakable Denim is tougher than standard denim — 133 times tougher to be exact. The toughness comes from a blend of cotton and a material known as UHMWPE, or Ultra High Molecular Weight Polyethylene. It's serious stuff, and provides 360º torsional strength with big-time burst and abrasion resilience. And despite those hardcore facts, it's surprisingly light and is made to be worn all day and night.
