A bridle that is fit correctly does not hinder a horses natural head carriage nor way of doing anything.
A caveson fit and adjusted does not impede a head nor stop breathing as needed by the animal.
That is true though for all tack, not just bridles.
Well fitting tack, all equipment is a compliment to the animal not a deterrent.
I think, no I know there is a lot of gimmicks today in the equestrian world...
Called marketing, advertising, endorsements and story-line given to separate a fool from their money is what my grandparents would of said.
There is also the "fad and fashion" trend that makes many jump on the band-wagon and buy because so-and-so has so I must now get...
See it in saddles, rider apparel, bridles, bits...just everything regardless of discipline.
Even food and supplements fed are often marketing strategy...
Somethings are improvements, but most are a glorified new name for same merchandise.
I personally am a tough sell...don't buy into the hype, marketing and advertising gimmick.
For me to buy that bridle you would have to prove to me
there is a marked improvement in my horses way of going that I can see, feel and watch a change take place under the exact same riding conditions with only a headstall change occur to part my $$ from my pocket.
