Built for the jobsite and the trail, Adventure Andy Unbreakable Boot Laces are braided from 12 strands of UHMWPE (ultra-high molecular weight polyethylene), the same fiber used in modern combat helmets. Pound for pound they're about 15 times stronger than steel and tougher than Kevlar, yet lighter than cotton. A waxed polyester outer jacket grips your knot so it stays tied all day.

• Over 1,100 lb breaking strength
• Waterproof, so they won't freeze stiff in the cold and won't rot or mildew if your boots get put away wet
• Resists oils, solvents, acids and alkalis found on the job
• Sold by the pair
