Fits well with Leatt Neck Baces that sons had for a few years. They are happy with the way the chest protector attaches to the neck brace. Seem to be of an excellent quality, however gave three stars each for durability and performance only because that is unknown because they just got them. Time will tell. I will say that the neck braces have held up extremely well, and if the chest protectors are the same type of high quality Leatt product, they should also prove durable. A good purchase because the style also adds protection to the sides of the body in addition to chest and back.
