Leatt – Jersey GPX 4.5 Pants

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 Pants. These are some of the best motocross pants on the market.


The Leatt GPX 4.5 pants are design to be both comfortable and durable. The pants are constructed out of 600 denier nylon fabric. 600D is a very strong nylon that is perfect for the wear and tear these pants will be exposed to. The seat of these dirt bike pants is made out of an even stronger 1000D nylon, to ensure this critical area can withstand abuse. The inner leg is constructed out of Amara fabric. This fabric is very similar to leather in both look and feel. Amara provides an excellent gripping surface. Having this material on the inner leg of these pants allows the rider to have better control of the bike. In addition to the durability of the pants, they are also very comfortable. The dirt bike pants come pre-tailored for a more comfortable fit.  The knees have a two point ventilation system to keep them cool and comfortable. The vents are made out of the X-flow mesh material to afford maximum airflow. This ventilation is especially important while wearing knee guard. These pants are one of the most comfortable and durable motocross pants currently available.


These pants are loaded with many other features that further separate the GPX 4.5 pants from other motocross pants. The knee caps are 3D molded with extra knee cap reinforcement. Having extra room in the knee affords the rider the option to wear knee protection underneath. The dirt bike pants are constructed with stretch panels around the knees that increase the elasticity of the pants. All the zippers on the pants are Japanese YKK manufactured. They are reinforced with hidden stitching for a sleek look. The inner lining of the dirt bike pants is made of moisture wicking mesh lining. Meaning, the lining draws perspiration away from the skin and onto the surface of the fabric where it can evaporate. This effect keeps the rider feeling cool. This layer is also uses a zinc pyrithion to reduce odor. The waist has a micro adjuster so every rider can have a custom fit. The waist band itself is lined with silicone to prevent a jersey form coming untucked.
