5/8" Nylon Long Line

I bought three lines. I needed a non grippy one ( this one) for general tracking and my older slower dog..I needed a more grippy for my strong puller who moves fast..(3/4" easy grip) And I wanted lightweight ( 3/8 sure grip) This nylon 5/8 moves in your hands to quickly adjust to the movement of the dog. It is not rough. It is slippery in the rain, and with non grippy snow gloves. So that's when I switch to the grippy ones
