My dog carried 1.8kgs (primarily her food and making up <10% of her bodyweight) in this harness over a couple of days hiking. It’s a little fiddly to do up/undo the catches, but that is a minor gripe and I’m sure I will get better at it over time. A couple more attachment points for leads eg front (no pull) and in front of the handle would be good. I didnt really use the stretchy bungees aside from attaching a light to the top one. There is a lot of reflective material built in. The harness is good quality and the dog wasn’t bothered about wearing it. She loved the trip - a happy dog - and that makes me happy too.
