This bit is a lightweight bit due to the fact it is hollow! The hollow mouth bits should be checked regularly as sometimes with them being hollow they can dent if the horse chews. The Hollow mouthed bits are renown for being milder or kinder than the solid mouth pieces, this is because the hollow mouthpieces are thicker in diameter which means the pressure of the mouthpiece on the lips is distributed over a larger area, this may be the case for those horses who have enough room in their mouths, but it also may prove uncomfortable in some cases (e.g. those horses with thicker lips and thicker tongues) and may result in the horse not being able to close their mouths as they have too much in there! - Please be aware that if you use such a thick bit, not to use it with a flash noseband as you may restrict your horse from swallowing.
