Profi-tunnel is focused on training and racing in agility. Its wire spacing is 150 mm apart, making the tunnel more durable and better shaped into different positions. Since the tunnel is sewn , it does not mind temperature fluctuations, so it is great for outdoor use. However, even when used internally, it is a great helper to keep your dog in shape even during intense exercise. The length of the tunnels is from 3 meters to 6 meters in various colors.
