Ask ten drivers which material lasts longer, and you'll get ten different answers — usually depending on which one they've used for the last decade. The honest answer is that both Biothane and leather can last for years, but they get there in very different ways, and the material that wins for daily driving isn't necessarily the one that wins for occasional showground use. Here's what actually determines how long a harness holds up, material by material.
What Actually Determines Harness Lifespan
Durability isn't just about the raw material — it's about how that material responds to the conditions it's actually used in. Frequency of use, exposure to moisture, storage conditions, and how consistently the tack is cleaned and conditioned all affect how long any driving harness will last. A harness used daily in a working yard faces very different wear from one that comes out for shows a handful of times a year, and the material that thrives under one set of conditions can struggle under the other.
Biothane: Built for Repetition
Biothane is a PVC-coated webbing material, and its biggest advantage for daily driving is consistency — it performs the same way whether it's day one or year five. It doesn't absorb water, so there's no risk of it drying out, cracking, or developing mildew in damp tack rooms or after a wet hack. UV exposure over many years can cause slight stiffening, but this happens gradually and rarely affects structural strength. For a harness that's hitched up daily, rinsed off, and put straight back into use, Biothane's resistance to moisture and rot is what gives it the edge — there's very little maintenance standing between one use and the next.
Leather: Built to Age, Not Just Endure
Leather behaves differently — its longevity is tied directly to how well it's conditioned. Vegetable-tanned leather that's cleaned with saddle soap and fed regularly with a conditioning oil can genuinely outlast Biothane in dry, well-maintained conditions, developing a supple, broken-in feel that many drivers prefer for showing. The trade-off is that leather is far less forgiving of neglect: skip conditioning for a season, leave it damp after a wet drive, or store it somewhere humid, and cracking, stiffening, or mould can set in far faster than most owners expect. Leather rewards routine care and punishes inconsistency, which is exactly why it tends to suit occasional or showground use better than a daily hitch-up-and-go routine.
Head-to-Head Comparison
| Factor | Biothane | Leather |
|---|---|---|
| Moisture resistance | Excellent — doesn't absorb water | Poor if left wet; needs drying and conditioning |
| Maintenance required | Minimal — wipe clean | Regular cleaning and conditioning |
| Lifespan with neglect | Holds up well | Degrades quickly — cracking, stiffening |
| Lifespan with consistent care | Long, stable performance | Can outlast Biothane; develops with use |
| Best suited to | Daily driving, all-weather, working yards | Showing, occasional use, dry storage |
Which One Should You Choose?
If your harness comes out most days regardless of weather — and especially if conditioning tack after every use isn't realistic — Biothane is the more dependable choice for daily driving. It's built to shrug off the exact conditions that wear leather down fastest: damp storage, inconsistent care, and repeated exposure to the elements.
If your harness is used more occasionally, kept somewhere dry, and you're willing to keep up with regular cleaning and conditioning, leather can match or exceed Biothane's lifespan while giving you the classic look many riders want in the show ring.

In daily-use, all-weather conditions, Biothane often lasts longer simply because it doesn't rely on regular conditioning to avoid cracking or drying out.
Yes, but it requires a consistent care routine — cleaning and conditioning regularly, and making sure the harness is fully dry before storage to prevent mould or stiffening.
Biothane can stiffen slightly after years of UV exposure, but it doesn't crack, rot, or absorb moisture the way leather can, so this rarely affects its usability.
Biothane is the more practical choice in consistently wet or humid conditions, since it doesn't need to be dried and conditioned after every use like leather does.
For showing or occasional use, leather's classic appearance and the way it softens with wear make it a worthwhile choice — the extra maintenance is easier to keep up with when the harness isn't used daily.
