Did you know that...
fleece achieves its warming effect not through weight, but through trapped air pockets? These tiny cavities act like natural insulators – they store heat exactly where your horse needs it, while simultaneously wicking moisture away. This creates thermal performance without any padding – lightweight, effective, and durable.

FAQ
What distinguishes “Hook&Hold” from other systems?
With SUNRIDE, you don’t need to read up on which rugs are compatible with our system, because all of our outer rugs – whether winter rugs, turnout rugs, or stable rugs – are equipped with “Hook&Hold.” This means you can attach one or even two under-rugs at any time and without any effort. You can find all the details above under the “Hook&Hold” section.
Is the “Hook&Hold” system compatible with rugs from other manufacturers?
Our innovative combination technology has been specially developed for our own outer rugs and under-rugs and is therefore not compatible with rugs from other manufacturers. This is the only way we can ensure that all parts fit together perfectly and function reliably – for maximum comfort and safety for your horse.
Why a fleece liner instead of a rug with integrated fleece?
A key advantage is the flexibility: with the fleece under-rug, you don't need to buy a separate rug with permanently integrated fleece. Instead, you can simply upgrade your existing SUNRIDE turnout rug, stable rug, or winter rug. This has two major benefits: firstly, you can remove the fleece liner flexibly at any time. This is extremely practical and helpful, especially in rapidly changing weather. Secondly, you can wash it separately and thus keep it hygienically clean. This is not possible with rugs that have permanently sewn-in fleece, as the entire rug would have to go into the washing machine, which is much more cumbersome and damages the waterproofing.
Can I use the fleece liner without an outer rug?
No, the fleece liner is designed to be combined with a turnout rug, stable rug, or winter rug and is secured using a simple fastening system (Hook&Hold). This ensures it stays securely in place, doesn't slip, and performs its function perfectly.
Can I also use the liner if my horse is slightly damp?
Yes, as long as your horse is only slightly damp, the fleece under-rug is a great choice. It ensures that moisture escapes while keeping the back pleasantly warm. This means you don’t have to wait a long time for your horse to be completely dry before putting on the outer rug.
Can the liner also serve as a replacement for a full cooler rug?
It is not intended as a complete replacement, but rather as a smart addition. The fleece under-rug supports the cooling-off process in combination with an outer rug, making the system much more versatile. While it cannot completely replace a dedicated cooler rug, it significantly shortens the time it takes for the coat to dry.
Security Information
- Only use for the intended purpose as a sweat rug for moisture wicking and temperature regulation.
- Do not use directly on open wounds, skin injuries, or severely irritated areas of skin.
- Check for damage, loose seams, tears, or defective fastenings before each use.
- The rug must not be used further if it is damaged or shows signs of significant wear.

- Clean only according to the care label – do not use chemical cleaning agents, bleach, or solvents.

Tip: Thanks to the Hook&Hold system, the fleece inlay can be flexibly combined with other SUNRIDE under rugs to individually adjust the level of warmth.
The fleece inlay is the ideal solution when you want to respond flexibly to temperature and weather conditions. It complements your rain or winter rug precisely where horses need warmth the most: in the back and kidney area. At the same time, it supports the cooling-down process by absorbing residual moisture and drawing it away from the body. This keeps your horse comfortably warm without overheating or chilling. Thanks to the Hook&Hold system, the inlay sits securely under the rug, does not slip, and can be quickly attached or removed as needed—ensuring maximum adaptability in everyday stable Management.
-
Hook&Hold – flexible combinations, secure fixation: Our smart solution helps you quickly and securely connect SUNRIDE outer blankets and under blankets. Featuring a loop and Velcro closure in the front and a practical clip system in the back, everything stays in place – even during movement. This system is a flexible companion, especially in rapidly changing weather. You can combine a maximum of two underrugs with one overblanket.
-
Extension for rain and winter blankets – for extra warmth: Our fleece underrug is the perfect extension for our rain and winter blankets. Inserted in just a few simple steps, it adds an extra soft layer of warmth, absorbs moisture, and stays securely in place. This way, the fleece liner makes the rain sheet warmer and more comfortable on cool days, while in the winter blanket it provides extra comfort – offering additional warmth, absorbing moisture, and remaining lightweight and practical.
-
Warms the back and kidney area – protects the sensitive core of the body: The sensitive back and kidney area requires special protection – this is exactly where the fleece underblanket comes in. It stores soothing warmth where horses are most prone to tension, creating a comfortable, even environment under the blanket. In this way, the horse stays relaxed and well protected, even in cold or wet weather.
-
With sweat-wicking function – reliably transports moisture to the outside: Thanks to its sweat-wicking function, the fleece liner reliably transports moisture to the outside. This keeps the horse comfortably dry after training or in changeable weather, without getting chilled. The combination of warmth and quick moisture absorption makes the blanket especially practical for everyday use.
-
Double-sided anti-pilling fleece – durable in both shape and function: The material is finished on both sides to ensure it remains smooth and high-quality even under heavy use. Even after frequent washing or intensive wear, it impresses with a well-kept appearance, shape retention, and comfortable feel – inside and out. This way, the Fleece underrug remains a reliable companion in the long run.
-
Breathable – for a pleasantly lightweight feel: Fleece stands out with its breathable structure: moisture can escape while the fabric gently conforms to the body, ensuring a consistent wearing comfort. This way, the horse stays protected even during extended use, without heat buildup.
-
Quick-drying – ready for use again in no time: Fleece is characterized by its easy-care structure: after washing or everyday exposure to moisture, the material is quickly ready for use again. This saves long waiting times, makes handling especially simple, and ensures the under blanket can be used again without delay.
-
Machine washable – easy-care for everyday use: The fleece layering rug is easy to care for and can be quickly cleaned at 30°C without losing its shape. This keeps it hygienic and fresh at all times – for optimal protection and comfort.
Did you know that… fleece doesn’t generate its warming effect through weight, but through tiny trapped air chambers? These small hollow spaces act as natural insulators – storing warmth exactly where your horse needs it while at the same time allowing moisture to escape. This creates thermal performance without filling – lightweight, effective, and long-lasting.

Why choose a fleece liner instead of a blanket with integrated fleece?

Yes, as long as your horse is only slightly damp, the fleece liner is a good choice. It allows moisture to escape while keeping the back comfortably warm. This way, you don’t have to wait until your horse is completely dry before putting on the top blanket. -

It’s not intended as a full replacement, but rather as a smart addition. The fleece underrug supports the cooling-off process in combination with a top blanket, making the system more versatile. While it can’t fully replace a dedicated sweat sheet, it does noticeably shorten the time until the coat is dry.
