Leatt · Chest Protector · Moto / ADV / MTB
The Leatt Chest Protector 4.5 Hybrid is a lightweight, hybrid-design chest protector built for Moto, ADV, and MTB riding. It pairs hard shell chest coverage with light, ventilated FlexMesh Pro impact protection, while the back uses soft, ventilated 3DF impact foam designed to form to the rider’s body for comfort.
Its construction uses flex joints and soft impact foams to support 3D flexing and a close, stable fit. Elastic straps help keep the protector positioned, and the BraceOn system is designed for a seamless neck brace fit, with a removable rear plate to support BraceOn compatibility.
Construction
This chest protector is CE-tested and certified as impact protection, with Chest EN1621-3 Level 2 and Back EN1621-2 Level 2. The front combines a hard shell with FlexMesh Pro chest protection, while the back uses 3DF AirFit impact foam to balance structure with comfort in a hybrid layout.
Comfort
Flex joints and soft impact foams are used to allow 3D flexing and an exceptional fit that moves with the rider. Elastic straps help maintain secure positioning during use, and the lightweight hybrid design is intended to keep the protector comfortable for long days in the saddle.
Fitment
The 4.5 Hybrid is built around Leatt’s BraceOn system for a seamless neck brace fit. It is listed as BraceOn compatible and uses a removable rear plate, letting the protector interface with a compatible neck brace setup while keeping the chest-and-back layout streamlined.
Construction
Leatt’s 4.5 Hybrid combines different protection structures in one piece: a hard shell and FlexMesh Pro impact protection across the chest, and soft, ventilated 3DF impact foam across the back. The goal is to deliver maximum ventilation in the front while keeping soft comfort against the back, with flex-focused design details that help the protector conform to the rider rather than feeling rigid.
