I purchased this leash as a functional ultralight option for my backpacking excursions with my dog. I pair it with a lightweight joring hipbelt and the Ruffwear Trail Runner Vest (which I resewed to make it function as a joring harness). With this setup, and my dog's boundless energy, he is able to pull me along some stretches of the trail while also doing his own water carry. I've only used this once so far on the trail, but it worked exactly as I hoped and has added only 2.2oz to my kit. It is a bit thinner and shorter than Ruffwear's other bungee leashes and I think extensive pulling will test its durability, but for my purposes, it's perfect. The only thing I dislike is the clasp; it's a ridiculous design that is not user-friendly, but I can get over it for the functionality of the rest of the leash.
