HP-1 has a wider shaped top piece, which ensures a pleasant distribution of pressure on the neck.
HP-2 is a model with a spacious cut out for the ears. The very wide top piece with soft padding ensures a pleasant distribution of pressure for horses with a long and wide neck.
HP-3 is a crown piece with a spacious cut out for the ears, which furthers the freedom of movement. This model has a narrower top piece than the HP-2.
HP-4 is a model well suited to a horse with wide jaws and wide neck. By means of the three pillows, the pressure on the neck is pleasantly distributed and as such well fitted to the wide jaws.
