I love, love, love this harness. My son is notorious for running off in the store. This product is simple and a great price. It doesn't cut into him at the shoulders. The harness offers a snug fit, without being too tight. It is adjustable, via the Velcro closure. I love that the the Velcro is in the back, so little hands can't undue the harness and slip out. This product also offers several variations on how to use the "leash". Handheld or hooked to a cart/stroller. Awesome product! I would recommend this to any parent with antsy-pantsy children!
