Re: Carting & harnesses
Hmm, no carting as such. Some Weight pull though. And in theory the harness used for weight pull can be used for carting, though its not ideal unless working heavy loads. Note, the other way around doesn't work, carting harness should not be used for weight pull. The weight pull harness is 2inch poly webbing lined with fleece (think 'Polar' fleece, not sheeps wool fleece) for padding on the chest and shoulders.
Most of the actual carting harness I've seen are usually leather, though I don't see why webbing wouldn't be fine.
