Oh absolutely no malice or argument meant - sorry if it seemed that way. Unfortunately, I have quite a bit of muzzle experience, and the Baskerville despite being the far superior muzzle the clips are dubious, the best ones have a proper buckle and strap.
The fabric muzzle does allow the dog to pant and be comfortable in general but I agree that on a really hot day or when strenuously exercising they are far from ideal because of the restriction around the whole of the muzzle. I have met quite a few dogs (usually shepherds) when the first time you fit a muzzle go bananas and with a Baskerville, get their claws in the basketwork, scratch their faces to bits and if a clippy type get them off no problem. For getting these dogs used to muzzles I find the fabric ones invaluable as they find them more comfy and less able to get off. You would hope a good owner will upgrade to a Baskerville eventually as they are much safer. There may just be some owners whose dogs are vile in a Baskerville muzzle and will injure themselves but will tolerate a fabric one and for our own safety we would rather they wore something. One downside being that if the fabric muzzle fitted comfortably and not too tight the dog can still nip. I would much rather any dog be in a Baskerville any day of the week but I have the fight the corner of the fabric muzzle as it can be a useful aid and in some cases is better than nothing.
Hope that explains a bit more
