The Striped Vest is just right for any time of year for your little dog! It's sturdy but light-weight canvas. The Striped Vest is adjustable with velcro strips. And it's secure with a buckle lock on the back with 2 leash rings over it. Plus, it's the cutest harness we've seen in quite a while! Roc (in Blue) and Golly (in Pink) are enjoying a warm day wearing the new Striped Vest. There's even a ring on a tab in front for your little one's ID Tag!
