 Leatt – Jersey GPX 4.5 Windblock

Dr. Leatt filed his first neck-brace related patent in 2003 and went on to found the Leatt Corporation in 2007. In less than a decade, Leatt has become one of the leaders in the body armor and protective gear industry. Leatt manufactures some of the most innovative and thoughtful protective gear, inspired by the top medical professionals and biomechanical engineers in the industry. Since the introduction of the acclaimed Leatt-Brace, Leatt has expanded and diversified their product catalog.  The Leatt Corporation continues to release new products that further establish themselves as the industry leader in quality, safety and performance. The GPX line of motorsports gear, body armor and apparel is the newest line of products from Leatt. Included in this release is the brand new Leatt GPX 4.5 Windblock Jersey. This is one of the best motocross jerseys on the market.


The entire dirt bike jersey is made out of Windblock fabric, a material designed to withstand all weather conditions. This material offers the best protection against the chilling effects of wind. Not only does this prevent wind from penetrating the rider, Windblock fabric is breathable. This prevents perspiration build up and the rider from overheating. This fabric is moisture wicking, meaning it pulls perspiration away from the skin and into the jersey for evaporation. The 4.5 Windblock dirt bike jersey is great for hot days too, especially when there is a lot of moisture in the air. The chest, arms and sides of this jersey are covered in a dirt /water repellent. Its moisture wicking properties, dirt & water repellent, and wind blocking ability makes this one of the best motocross jerseys for any type of environment.


The Leatt GPX 4.5 Windblock Jersey has many other features that make it one of the best motocross jerseys in the world. This jersey has long sleeves to help protect the rider’s arms. The back panel is made of an anti-odor material. The collar of the jersey allows the use of a Leatt neck brace in conjunction with a full face helmet. The jersey can be worn without the use of a neck brace as well. The fabric is elastic which creates a snug fit for the rider, perfect for wearing underneath body armor to prevent bunching. The seams inside the jersey are taped to create a more comfortable fit and to help reinforce the stitching. The tail of the 4.5 dirt bike jersey is lined with silicone, which helps the jersey to remain tucked into dirt bike pants. The 4.5 Windblock is only offered in one color, but is the only model in the Leatt Jersey line that offers the 3XL size.
