Leatt - 4.5 Pro Chest Protector

 Dr. Leatt filed his first neck-brace related patent in 2003 and went on to found the Leatt Corporation in 2007. Since the introduction of the acclaimed Leatt-Brace, Leatt has expanded and diversified their product catalog. In less than a decade, Leatt has become one of the leaders in body armor and protective motorsports gear. Leatt manufactures some of the most innovative and thoughtful protective gear on the market. Their protective gear is designed by medical professionals and biomechanical engineers to ensure their products take safety and performance to the next level. Leatt has introduced the new Leatt 4.5 Pro chest protector which continues to uphold their reputation as the industry leader in quality, safety and performance. The 4.5 pro chest protector is a great addition to the Leatt line of products, and is one of the best chest protectors on the market.


The 4.5 Pro chest protector is guaranteed to prevent riders from sustaining any injuries on the occasion of a fall or impact. It is CE and FFM certified as protective equipment and is awarded a Leatt® protection score of seventeen points. It offers excellent protection to the chest, back and shoulders of the rider. The shoulder plates are secured by an elastic belt that straps to the upper arm to prevent slippage, which is a great feature to have in a dirt bike chest protector. Additionally, the chest protector also adds protection around the rider’s flanks. It is closer to fully body armor than a traditional chest protector. Adjustment straps are located around the middle of the chest protector in case the rider needs to tighten or loosen it for a more custom fit. The 4.5 Pro is made of multiple articulating layers of protective armor. This chest protector is one of the heaviest chest protectors made by Leatt, weighing 3.2 pounds, due to all the added protection afforded by the multiple panel design.


Underneath the hard protective shell lies a 3DF Airfit soft ventilation foam layer. It provides cushioning between the rider and the hard outer shell. This layer is soft and safe, providing both comfort and added protection. The foam absorbs energy and becomes harder upon impact. Underneath the foam lies a mesh layer to allow even more airflow to keep the rider cool, even at low speeds. The Leatt 4.5 Pro chest protector is one of the most protective and well ventilated chest protector on the market. Like many other Leatt products, the 4.5 Pro can be worn with or without the Leatt neck brace. This dirt bike chest protector has recesses engineered into the front and that integrates with the neck brace perfectly. The chest protector can be worn over or underneath a jersey depending on the preference of the rider.
