'Legs Out' Mesh Backpack Style CarrierA favourite for biking because it holds the dog snugly in place, this is also a great carrier for just walking around! Adjustable crossover straps buckle over both of your shoulders for a secure fit and quick on and off. The carrier zips up both sides, so you can easily lay the whole thing out flat and do it up around the dog. There's even a safety clip for harness or collar though most dogs can't squirm out of these. Size Back Length Chest Girth
