Leatt - Jersey DBX 4.0 Ultraweld

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. Since the introduction of the acclaimed Leatt-Brace, Leatt has expanded and diversified their product catalog.  Leatt manufactures some of the most innovative and thoughtful protective gear, inspired by the top medical professionals and biomedical engineers in the industry. The Leatt Corporation continues to release new products that further establish themselves as the industry leader in quality, safety and performance. Leatt has launched an all new apparel line that includes brand new DBX jerseys. The Leatt DBX 4.0 Ultraweld Jersey is one of the best cycling jerseys on the market.


The entire jersey is made out of the lightest material in the Leatt DBX line. The 4.0 Ultraweld is designed to be much lighter than the 5.0 All Mountain. This material is windproof and is great for repelling dirt and water, making it one of the best cycling jerseys for any type of environment. It is the perfect material for riding in the rain and mud because it keeps the rider dry. The keeps out the cold air while still allowing moisture to escape. This prevents perspiration build up or the rider from overheating. The elbows on a mountain bike jersey are prone to rips and tear from the rough terrain. That is why Leatt has reinforced the DBX 4.0 Ultraweld Jersey with brush guard material to ensure the jersey can withstands an extreme lifestyle. Brush guard is a flexible film that is bonded with the base level material of the jersey, which adds resistance to scratches and abrasions.


The 4.0 mountain bike Jersey has many other features that make it one of the best cycling jerseys in the world. The jersey is long sleeve to help protect the rider’s arms. 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. Leatt uses bar tack stitching for seams in critical areas for reinforcement. The tail of the 4.0 mountain bike jersey is lined with silicone, which helps the jersey to remain in place. The jersey is equipped with a zipper pocket containing a microfiber goggle wiper. The jersey comes in three colors that match the Leatt bicycle shorts.
