What is biothane synthetic leather?
Hi-tech polymers are laminated around nylon for a leather look but many more advantages:
It is stronger than leather, lightweight, easy to clean and comfortable on the horse.

What is the difference between the Deluxe and Standard bridles?
They work exactly the same and look similar, except for the padding on the noseband/browband. It is made from antigall ‘waffle’ look material on the deluxe, and a smoother padded leather material on the Standard.
Both have stainless steel or brass fittings.
The Deluxe Biothane bridles have extra stitching on the headpiece to match the cheekpieces.

Standard Biothane has a thicker polymer coating than the Deluxe, but is no less comfortable for the horse. This tends to make it stiffer when cold but when warmed up, it is just as flexible as the Deluxe Beta biothane. The Standard Biothane received 5 stars for quality from a test by Cinch Magazine - see the "LightRrider Bridle passes tests with exellence'report here.

The Beta Biothane used for the Deluxe is manufactured in the USA and the bridle is made in Australia, while the Standard biothane bridles are manufactured in India. China and India make more than 90% of the world’s quality equestrian equipment due to more affordable labour, bringing you more affordable equipment.
