By using a separate underblanket, your horse's regular blankets can easily be adapted to lower temperatures. The lightly padded "Rhyolite" liner provides extra warmth without adding extra weight to the muscles. The lining is breathable and has a smooth surface, preventing chafing.

The "Rhyolite" is equipped with Welltex® material, which can promote blood circulation by reflecting body heat as infrared energy. This can have a relaxing effect on the muscles, reduce stiffness, and be beneficial for discomforts such as osteoarthritis. This blanket is also great for warming up before riding and for support during recovery. "Rhyolite" features Velcro closures at the neck and over the tail for easy attachment to the "Obsidian" Turnout blanket, carabiners at the back, and a mounting kit for other blankets.

The underblanket is available with two different fillings, 100 grams and 200 grams.
