It has minimum break strength of 425 lbs. and a diameter of 3 mm. The smaller size makes 425 paracord a great alternative for projects where 550 paracord is bigger than your needs.This Paracord has many of the same popular practical uses as 550 paracord: survival bracelets, boot laces, key chains, handles for weapons, belts, dog leashes, and much more. It is also great for creative crafting and other DIY projects.
