I really like the design and function of this harness: it fits my dog well and lets her run naturally. She enjoys using it. However, the materials used, particularly the webbing, are very light if you are used to mil-spec components: we've been using the harness for only two weeks, and already I've had to repair the webbing when it tore from running by some brush. I would love the same harness design but with mil-spec 17337 webbing.
