If you’ve ever shopped for a horse rug—especially a turnout rug—you’ve likely come across the word “denier”.
But what exactly does it mean, and why is it important when choosing protection for your horse?
In this guide, we’ll break down what rug denier is, how it affects durability and performance, and why choosing the right denier matters more than you might think—especially if your horse is turned out daily, loves to roll, or is a known rug-wrecker.
What Is Rug Denier?
Denier (D) is a measure of the thickness (or density) of the individual yarns used to weave a fabric.
Technically, it refers to the weight in grams of 9,000 metres of the fibre used.
- A higher denier means thicker threads → stronger, more durable fabric
- A lower denier means finer threads → lighter fabric
In horse rugs, denier usually refers to the outer shell fabric—typically made of polyester or nylon—which is responsible for the rug’s tear strength, abrasion resistance, and overall toughness.
Why Is Denier Important in Turnout Rugs?
Turnout rugs are exposed to a lot—weather, mud, rubbing, biting, rolling, and rough play.
The denier rating of the outer fabric plays a huge role in how well your rug holds up.
1. Durability & Tear Resistance
A higher denier offers greater resistance to rips and punctures. The new Equilibrium Endure Turnout Rug uses a strong 1680D outer, making it one of the most durable rugs on the market.
2. Weather Protection
High-denier rugs also offer better wind and water resistance. Thicker fabrics naturally repel weather better, and they hold up more effectively against prolonged rain and harsh winter conditions.
3. Longevity
Investing in a higher-denier rug may cost more upfront, but it pays off in the long run.
With tougher yarn you should be dealing with far less repairs, and in the unfortunate event where your horse does manage to rip it the damage is often more contained and easier to patch, saving you time and money.
Which Denier Is Right for Your Horse?
Here’s a quick guide to help you match denier to your horse’s needs:
|
Denier Rating |
Best For |
|
600D–840D |
Calm horses, dry climates, or occasional turnout |
|
1200D |
Regular turnout in normal weather conditions |
|
1680D+ |
Playful, or destructive horses; prolonged rain and wind, those who feel the cold |
When choosing a turnout rug, rug denier shouldn’t be overlooked. It’s one of the clearest indicators of how long your rug will last, how well it’ll protect your horse from the elements, and how much hassle it will (or won’t) give you mid-season.
If you're looking for:
- Exceptional durability
- Strong weather protection
- A reliable option for all-day turnout
…then the Endure Turnout Rug with 1680D outer is built to exceed expectations—season after season.
