When only the highest-strength thread will do, look no further than SGT KNOTS Kevlar® Sewing Thread.  For leather working, securing a canvas, and any other application where you need a smooth stitch that will hold up to anything you and the weather come up with, Kevlar® is the gold standard.  It's what the military has been using for decades, and this Kevlar® sewing thread is exactly what the fine folks in our armed services are using today. 

The wilderness/survival/camping applications of this thread are virtually endless.  Repair gear, stitch together a tent, set hunting traps, and make fishing nets.  Its high tensile strength, resistance to wear by moisture and abrasion, and ability to withstand prolonged exposure to high temperatures means this Kevlar® thread can help you catch your dinner and string it up over the fire, too.  There's a reason this is frequently the thread of choice in military applications, and SGT KNOTS is proud to bring the same quality and affordability to the civilian population.

Kevlar®'s superior strength and fire resistance make it the thread of choice when being used in high-stress operations being exposed to extreme heat.  Spun Kevlar® is available in many popular colors and has a high-speed coating to prevent sewing problems.

Great product

This is a great product, as long as it’s not exposed to the outside elements for very length of time. It’s not designed for outdoor gear. It’s best designs for clothing in my use anyway. The tensile strength is not what you would expect from Kevlar, but utilized properly. It is a good product.
