Leatt – Jersey GPX 4.5 X-Flow

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 biomedical 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 X-Flow Jersey. This is one of the best motocross jerseys on the market.


The GPX 4.5 X-Flow is a very comfortable jersey. The entire dirt bike jersey is made out of X-flow fabric, a lightweight mesh material designed to keep the rider cool. However, it does little to protect the rider from wind and water like other models, but excels in keeping the ride comfortable and refreshed. X‑Flow fabric is the lightest fabrics in the Leatt line of GPX jerseys. This jersey affords the rider the maximum breathability. Another feature this fabric has is its moisture wicking ability. It is designed to pull perspiration away from the skin and onto the fabric. Once this occurs, the moisture can evaporate which has a cooling effect on the rider. Because of this moisture wicking ability, this dirt bike jersey is ideal for hotter climates and humid environments. The light weight of the fabric, in conjunction with the breathability of the fabric, makes this one of the most comfortable motocross jerseys currently available.


The Leatt GPX 4.5 X-Flow 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 from dirt, mud or sun exposure. The collar of the jersey allows the use of a Leatt neck brace in conjunction with a full face helmet. The dirt bike 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. Leatt uses overlock stitching in its jerseys. Not only is this more comfortable for the rider, it reinforces the seams to make the jersey more durable, Over The tail of the 4.5 X-Flow dirt bike jersey is lined with silicone, which helps the jersey to remain tucked into dirt bike pants. The color palette of the 4.5 X-Flow jerseys match perfectly with both Leatt pants lines.
