The Black Diamond Nylon Runner offers a great, versatile climbing sling option. These are extremely useful in a variety of applications, affordable, and more durable than some of the other nylon slings we tested. They are a great choice for everyday, traditional climbing applications. They out-performed the Sterling Nylon Sling and even the Petzl FinAnneau Sling. They handle well, and its easy to tie and untie knots even after weighting. Though they are significantly bulkier and heavier than Dynex slings, they are a far better value.
