Whilst we love Velcro on our Drying Coats, our research revealed that Velcro is not practical for a coat that will be used on outdoor adventures. Velcro is not strong enough to withstand digging around in the undergrowth! The cool coat is fastened with a sturdy clip which holds the coats in place. Also, because the coat goes between the dog's legs, it not only cools the important chest area, but is more likely to stay in place and not twist.
