100% wool - a high-tech material from nature.
Our kidney rug made of 100% pure wool offers a better alternative to the classic kidney rug made of synthetic fibres. The natural material wool not only has a high-quality, beautiful look:
It is cuddly and lies great on the horse, does not slip - which is particularly important when riding. The wool rug is breathable, which means that when the horse sweats, the wool absorbs moisture and releases it again on the surface. The horse's body stays nice and dry. Even when it's drizzling - the woolen kidney rug is water-repellent and effectively protects against drafts and cold. The temperature-regulating property is also important for a riding rug, because the horse should neither overheat nor cool down too quickly when it sweats.
Our 100% wool rugs combine the high-tech properties of a natural material with a modern, timeless look. Longevity and high-quality workmanship for your horse.
Why we use the natural material wool for our new blanket collection!
Wool is one of the most extraordinary natural materials in existence and is often referred to as nature’s high-tech fibre – and for good reason. Its unique fibre structure enables it to regulate the horse’s body temperature naturally. This means it provides warmth when it is cold, whilst at the same time helping to release excess heat and moisture to the outside when the horse is working.
This property plays a crucial role, particularly in a kidney rug. During riding, the horse’s body temperature is constantly changing – whilst warming up, during work and whilst walking off. Pure wool supports this natural temperature change without heat or moisture building up under the rug.
Another advantage is its excellent moisture management. Wool can absorb moisture and transport it outwards without feeling uncomfortably wet. This keeps the climate on the horse’s back pleasantly dry and balanced.
This is precisely one of the exceptional properties of high-quality wool fibres and one of the reasons why it has been valued as a functional material for centuries.
When riding, movement generates heat. At the same time, depending on the intensity of the training, the horse begins to sweat. Added to this are external factors such as mist, damp air or light drizzle. In such situations, many synthetic materials lose some of their insulating effect or feel cool to the touch.
Wool behaves differently. The fine wool fibres can absorb and regulate moisture without the material immediately feeling damp or cold. As a result, the insulating effect is largely maintained and the back muscles are kept comfortably warm.
This natural property makes this natural material particularly appealing to riders who train regularly, even in changeable weather or during winter.
Yes – and it is precisely this breathability that distinguishes high-quality pure wool from many other materials.
Whilst the kidney rug protects sensitive areas from wind and cold, the natural wool fibre simultaneously ensures that excess heat and moisture can be continuously released to the outside. This creates a balanced microclimate directly against the horse’s body. This is particularly important, as whilst a rug should provide warmth, it must not cause heat to build up. If the muscles become too warm or moisture cannot escape, comfort is often compromised. Wool, as a natural material, regulates this process naturally.
Another advantage is that the fibre adapts to the changing conditions whilst riding. During the warm-up, it retains heat; during intense work, it aids moisture wicking; and during the cool-down, it helps the muscles to cool down slowly and evenly.
No. Although wool is primarily associated with winter and cold weather, it is suitable for a much wider range of uses.
Its temperature-regulating properties ensure that it does not simply provide warmth, but actively regulates the body’s temperature. That is why a woollen kidney rug can be an excellent choice, particularly on cool spring and autumn days or during crisp summer mornings.
Particularly during the transitional periods, temperatures and weather conditions often change within a matter of hours. It is cool in the morning, significantly warmer at midday, and temperatures drop again in the evening. Wool fibres naturally balance out these fluctuations and help maintain a comfortable climate whilst riding.
Many riders value this versatility in particular. Instead of needing several different winter rugs, a high-quality woollen kidney rug (or even a full-length cooler rug) can be used for much of the year – whenever extra protection for the back muscles is needed.
High-quality wool is surprisingly easy to care for. Thanks to the special processing, AIKO wool kidney blankets can be machine-washed in accordance with the relevant care instructions. Wool also possesses natural dirt-repellent and odour-resistant properties. It is therefore often sufficient simply to air the blanket thoroughly after use. As a result, woollen products often need to be washed less frequently than many synthetic materials. With the right care, a high-quality woollen kidney rug will serve both horse and rider for many years, whilst retaining its natural benefits such as breathability, temperature regulation and a high level of comfort.
A kidney rug protects your horse’s sensitive back, lumbar and croup muscles from the cold, wind and damp whilst riding. These areas in particular lose heat very quickly in low temperatures or when exposed to a strong draught. If the muscles become chilled, they can lose elasticity, which may affect the horse’s well-being and willingness to perform.
Kidney rugs are therefore used primarily during the cooler months – for example, during the warm-up, on a ride or when cooling down after training. They keep the muscles comfortably warm without interfering with the saddle or the rider’s aids. Thanks to their special cut, the saddle area remains clear, whilst the back and croup are reliably protected.
Clipped horses, older horses or animals with sensitive back muscles benefit particularly from a well-fitting kidney rug. However, even unclipped horses may need extra protection on cold or windy days, especially if they are being worked hard or are walking for long periods outdoors.
A kidney rug is used whenever your horse’s back muscles need to be protected from getting cold whilst riding. It is particularly useful in low temperatures, cold winds, damp weather or during longer walking phases when the horse produces less body heat.
Many riders use a kidney rug as early as the warm-up. This allows the muscles to warm up gradually and ensures they remain at a comfortable temperature during the first few minutes of training. The kidney rug has also proved its worth during a ride, when the horse is exposed to the wind and weather for an extended period.
The kidney rug is also frequently used at competitions – for example, between classes or during long waiting periods. Horses that have just been clipped or those with sensitive backs benefit from extra protection in such situations.
No – provided that the kidney rug is well-made, correctly cut and chosen to suit your horse. Modern kidney rugs are specially designed to protect the back and croup without restricting the horse’s natural movement. The saddle area remains clear, allowing the rider to control the horse as usual. At the same time, fastenings to the saddle or stirrup leathers, as well as a tail strap, ensure that the rug remains securely in place even whilst riding. This prevents it from slipping or chafing.
A well-fitting kidney rug follows the horse’s movements without tightening or creating pressure points. It is therefore important to choose the correct size. It should completely cover the sensitive back area, but be neither too long nor too short.
A good fit really pays off, particularly on longer rides or during intensive training sessions. The horse can move freely, whilst its muscles are reliably protected from the wind and cold. It is precisely this combination of freedom of movement and functionality that makes the kidney rug an essential companion during the colder months.
It is often assumed that only clipped horses need a kidney rug. In fact, many unclipped horses also benefit from extra protection – particularly in cold, windy or damp weather, or during longer rides.
Although the winter coat provides natural insulation, the back muscles can still become chilled in low temperatures, damp weather and strong winds. The body produces moisture, particularly during longer walking phases or after training. At such times, a kidney blanket helps to keep the muscles at a comfortable temperature and wick away moisture.
Older horses, horses with sensitive backs or those being brought back into training after long breaks also often benefit from additional thermal protection. The kidney rug does not replace the winter coat, but complements its natural function in challenging conditions.
Many AIKO kidney rugs can be personalized with your horse’s name or a custom message. The design features high-quality crystals, which are carefully applied to give the product an exclusive, elegant look.
The crystal personalization blends harmoniously into the kidney rugs design, making each piece truly one-of-a-kind. Whether it’s your horse’s name, a stable name, or a short message of your choice — this gives your kidney rug a very personal touch.
Personalized kidney rugs aren’t just a stylish eye-catcher in the stable and at competitions — they’re also a popular gift idea for riders. Since each personalization is custom-made, every item is one-of-a-kind.
Crystallized Monogram: a decorative detail that is completely individual!
Choose initials, branding or your horse's name as a personal touch! Our color palette of beautifully sparkling crystals is designed to inspire you and complete your bespoke look.
You can individualize the rug on one side (standard left side) or on both sides (left and right).
The crystals are set by hand and checked several times, so that you can wash your favorite item in the washing machine at 40°C as usual. You can also enjoy a 2-year guarantee with AIKO®!
Wool rarely needs to be washed. The less often wool is washed, the longer it retains its natural properties. It is often sufficient to let the blankets air out overnight, to simply brush out coarse dirt or to clean it in places with a little wool detergent and then with clear water.
However, our blankets can also be washed with a gentle wool washing program and wool detergent (30°C and max. 400 rpm spin).
It is best to straighten it out a bit after washing and hang it on the drying rack to dry (do not hang it).
