That scares me, living in Chicago. I have two hunting labs, I bought both the 20 and 40 size to see what fit best. I returned the 40 size with tags and ordered a second 20, one for each of my dogs. Still I was charged a restocking fee. This despite the fact that I emailed Clean Run to discuss this and was given an OK! The returned harness was only used for fitting purposes, never walking. So, one must ask if a fitting alone would damage the fleece to such a point as to ding me, then it's not a smart choice of material for a $90 harness. Further, why isn't the ring in front the same size as the larger top D-ring? There should be two box-x stitch on both sides of the ring, that is industry standard for webbing and ring use. The front D-ring rotates constantly and gets stuck with the leash clip in the corner every time. The fleece should be secure throughout its length, not just in the middle. I am constantly having to unbunch it. Ridiculous! Why don't they keep the fleece separate so that we can slide it over the straps and buckles completely after adjusting the fit, rather then have the webbing and clips scrape and slide over my dogs' coats and skin. Neoprene would be preferred to this fleece. Quite disappointed in the harness and the service at Clean Run. Penny wise, pound foolish, CR!
