If you've been buying leather leads and finding them cracked, stiff, or smelly after a few months of NZ walking, it might be time to consider BioThane. Here's an honest comparison of both materials across the factors that actually matter.

What Is BioThane?

BioThane is a coated webbing material — a polyester core with a polyurethane or TPU coating. It was developed for use in equestrian equipment (horse bridles, reins) where durability and weather resistance are critical. Dog lead manufacturers adopted it because the same properties that work for horses translate perfectly to dogs: it's tough, waterproof, easy to clean, and virtually odour-resistant.

Head-to-Head Comparison

The NZ Weather Argument

New Zealand's climate — particularly the North Island — involves a lot of rain. Leather leads that are regularly wet and not conditioned will crack, stiffen, and degrade within months. BioThane is completely unaffected by water. You can take it through a river, hang it dripping wet, and wipe it down 10 minutes later with a clean cloth. Zero maintenance, zero degradation.

For Kiwi dog owners who walk in all weather — and let's be honest, most of us do — BioThane is the more practical choice for everyday use.

Where Leather Still Wins

If aesthetics matter more than practicality, leather still has the edge. A well-made leather lead looks and feels premium in a way that's hard to replicate with a coated material. For show ring presentation or formal occasions, leather (properly maintained) remains the classic choice.

For everyday use, commuter walks, beach trips, and anything involving water? BioThane wins comfortably.
