Rhino Laces are built for the toughest jobs on the planet. They are 8 times stronger than steel by weight, maintain excellent dimensional stability in extreme hot or cold environments, have exceedingly low creep and very high fatigue resistance when compared to normal boot laces or paracord, have high resistance to breakdown from abrasion, acids, bases, flames, organic solvents, and salt water. Rhino Laces utilize a para-aramid fiber core covered with a blended sheathing for even more protection and come in many colors and sizes to fit you and your boots perfectly.
