We've spent the last two years designing the perfect harness for everyday walks, as well as the most epic outdoor adventures. No detail was left behind; we've thought of every feature to make this the most versatile harness you'll ever own. With two D-ring attachment points - one on the chest and one on the back - you have options for how to best walk your dog. The top handle allows you to give your pup a boost over boulders or grab them close if need be. Two reflective fabric strips border the handle, giving a bit of visibility at night. The body is made of a lightweight mesh fabric, breathable and super comfortable for long days, all year round. The harness fits by slipping over the dog's head, and has two side release buckles at the chest. Both the neck and shoulder straps are adjustable. SMALL = 16" - 22" around the chest (40.5 cm - 57 cm) MEDIUM = 23" - 30" around the chest (58 cm - 76 cm) LARGE = 30" - 42" around the chest (76 cm - 106 cm) --- Specs: SMALL - top panel length = 6", belly panel length = 8" MEDIUM - top panel length = 8", belly panel length = 10" LARGE - top panel length = 9", belly panel length = 14"
