The first and only stable rug in the world equipped with Outlast® Technology. An innovative line of rugs designed to maintain steady thermal comfort—regardless of ambient temperature.
• Reliable comfort even during major temperature fluctuations.
• Retains its performance even after repeated washing.
• Military-grade, highly tear-resistant outer fabric: 1680D Ballistic Nylon.
Horse owners around the world often struggle to choose the right rug for their horse and the weather. The challenge lies in the fact that a horse usually wears the same rug all day, until the caretaker returns to the stable. Traditional rugs have a fixed fill weight, so they cannot adapt to changing temperatures. As a result, the horse may overheat at one point and get chilled at another - sometimes several times in a single day.
That’s why we created the Winderen Thermoactive line of rugs. They actively regulate temperature by absorbing, storing, and releasing heat precisely when your horse needs it.
Thermoactive rugs come in two Zoom variants: winter (equivalent to 100-350 g fill) and transitional (50-200 g).

Benefits for the horse and the rider

Benefits for the horseStable body temperature regardless of the weather - even with major fluctuations.
Thermal comfort during activity - helps prevent sweating even during intensive sessions on a horse walker.
Improved overall condition - consistent thermal comfort supports immune function and your horse’s well-being.
Reduced risk of rubbing - thanks to vegan-fur inserts at key areas such as the shoulders and withers.

Benefits for the riderOne rug that replaces many - no more changing rugs depending on the weather. From now on, one rug for the whole season.
Durability of materials - Climashield® insulation combined with 1680D Ballistic Nylon ensures the rug retains its properties despite intensive use and repeated washing.
Real savings of time and money - no need to buy, wash, and store multiple rugs of different fills.
Less gear to store and transport - saving space in the stable.
Outlast® technology in Winderen Thermoactive rugs
Winderen Thermoactive is the first and only rug line in the world featuring patented technology from the German company Outlast®. This advanced solution uses phase-change materials - substances capable of storing and releasing heat multiple times as they shift state - to maintain optimal body temperature.
Outlast® technology was originally developed for NASA to provide astronauts with clothing able to withstand extreme temperature fluctuations in space.

Phase-change materials adjust depending on the horse’s skin temperature. When it rises, they absorb excess heat, maintaining comfort without overheating. When it drops, they release stored warmth, preventing chilling.
These materials are permanently embedded in the Thermocules® polymer coating, which retains its properties even after repeated washing.

Additionally, Winderen Thermoactive rugs help maintain a healthy skin microclimate. The technology not only regulates temperature but also helps prevent moisture buildup on the skin. This means your horse won’t sweat under the rug - even during a long exercise in the horse walker. With Outlast® in Winderen Thermoactive rugs, your horse will always feel not too hot, not too cold - just right. It is currently the most proven outer fabric ever available in horse rugs.

Proven effectiveness
From autumn through winter to spring - across the full rugging season - we conducted detailed tests of the rug’s thermoregulatory performance.
We divided horses into two groups, living in identical stable and weather conditions with the same daily activity. The only difference: one group wore Winderen Thermoactive rugs, while the other wore high-quality rugs from another well-known manufacturer.
We placed Orscana sensors, developed by the French company Arioneo, under all the rugs, recording temperature continuously, 24 hours a day.
The results exceeded our expectations!

During 7 months of testing (October to April), horses wearing Winderen Thermoactive Zoom 100-350 experienced continuous thermal comfort in outdoor temperatures ranging from -15°C to +17°C, regardless of activity level.
At the same time, horses in traditional rugs needed frequent rug changes with different fill weights - which still did not guarantee optimal comfort.

Exceptional durability - Climashield® fill
In Winderen Thermoactive rugs, we use Climashield® insulation, developed by an American company and known for outstanding resistance to compression.
Whereas standard rugs often use chopped synthetic fibers, Climashield® uses continuous fibers, ensuring superior durability and insulation.
Climashield® resists compression, retains its loft and insulation even when crushed, and dries quickly after getting wet. Most importantly, it does not lose its valuable properties even after repeated washing, which ensures long-lasting performance of the rug.
Specialist recommendation

“I’ve been using the Winderen Thermoactive rugs for a good year now and they really make our lifes easier! In the changing seasons it’s way easier to ensure a good climate for the horse without changing rugs constantly! Depending on temperatures they might even do all winter, maybe with another rug on top, if needed. I also really like the high quality durable make and the chic looks, making them perfect for shows aswell as home! I would say you can save at least one rug per horse, which makes it more sustainable aswell!
An added bonus is the personalisation Winderen offers on their products. Making it easy to put a brand, horse name or team logo on rugs or saddle pads!”
1680D Ballistic Nylon - ultra-resistant outer fabric
Originally developed for military use, 1680D Ballistic Nylon was designed to withstand extreme conditions and deliver maximum resistance to damage. In Winderen Thermoactive rugs, it serves as the outer fabric, combining outstanding tear and abrasion resistance with lightness and breathability.
The dense weave increases resistance to daily stable use, significantly enhancing durability.
It is currently the most proven outer fabric available in horse rugs.

Protection against rubsWe know rubbing is a common issue. That’s why we’ve added soft vegan-fur inserts at the withers and shoulders - positioned deep enough to protect the entire sensitive area, even in motion.

Secure fasteningIn the winter Winderen Thermoactive Zoom 100-350 version, we use military-grade, durable, and secure fastenings. They can be opened and closed effortlessly with one hand, while the mechanism prevents the horse from undoing the chest or belly straps.

Supporting comfort and immune healthOverheating, along with chilling, is one of the most common causes of discomfort in horses. It not only leads to sweating but can also compromise immune function over time. Choosing the right Winderen Thermoactive rug is a simple way to keep your horse comfortable - without the risk of negative consequences.

Saving spaceWe understand how challenging it can be to store multiple rugs - especially if you have more than one horse. Thermoactive rugs act as a thermal buffer, effectively replacing several rugs of different fills.
Less clutter, more space!

Environmentally friendlyOne Winderen Thermoactive rug replaces several rugs of different fill weights. This reduces material use and waste. And because our rugs are built to last, they retain their properties for many seasons - say goodbye to seasonal rug replacements.

Silicone tail strapEvery Thermoactive rug comes with a practical silicone-covered tail strap. It can be unclipped in seconds, making it easy to keep the tail area clean. Simply rinse under running water and dry - quick and simple.

Care and maintenanceAll rugs from the Thermoactive line, thanks to their high-quality insulation, retain their properties even after repeated washing. This makes them an extremely convenient choice for everyday care—they can be safely machine-washed at 30°C.

Complete the set with a hoodFor full-body thermal protection, you can pair your Winderen Thermoactive rug with a matching hood. For Zoom 100-350, choose the Thermoactive hood. For Zoom 50-200, you can choose either the Thermo Clear hood or the Softshell Thermo Clear hood.
