This rug is filled with polyfilling and is designed with the innovative TETRIS system. This system includes soft blocks on the left and right sides at the level of the withers, creating a tunnel that prevents the blanket from causing pressure or chafing. As a result, the horse's withers lie freely in the rug, ensuring optimal comfort and freedom of movement. Moreover, the rug remains stable in place, even during movement.- Innovative TETRIS system for optimal comfort- Includes leg straps, long tail flap and cross girths. 400 grams.
