Its a fair question and I will be mailing my ideas on this to Zeiss with whom I have had a conversation about this already.
I don't use objective covers myself as, for the most part, we don't suffer from dry and dusty / sandy conditions in the UK: its usually wet here.
But I have tried out the HT covers in the field and I have to say that I found the cover a nuisance dangling on the tether and getting tangled up with other observation instruments or cameras or with their straps. or with twigs and branches of scrub I was pushing through, or snagging on barbed wire fences I was climbing over.
My argument is not about the lack of decoration or distinctiveness but the lack of a truly premium functional solution.
There are other design options that I think would be more efficient and user-friendly and, no, they don't involve leather, gold-plated Zeiss logos or carbon-fibre effect inlays, titanium fittings or antique brass and wood :-O.
