Bull-it Mastiff Slim Jeans

Lightweight Construction

For riders, every gram counts—protection should be as light as possible without sacrificing safety. Unlike traditional armor that can feel heavy and restrictive, RE ZRO's open-geometry design minimizes material while maintaining structural integrity, creating an ultra-lightweight shield that integrates effortlessly with your gear. 

With RE ZRO®, protection doesn’t come at the cost of comfort or mobility. It’s designed for riders who prioritize performance and freedom of movement, so you can stay focused on the ride ahead—without feeling weighed down.

Vented Armor

RE ZRO’s open-geometry structure is designed for maximum airflow, offering superior ventilation compared to traditional impact protection. Continuous air circulation prevents heat buildup, keeping you cool and comfortable, no matter the conditions.

Conventional armor often traps heat and moisture, leading to discomfort over long rides. RE ZRO® actively promotes airflow and temperature regulation, helping reduce sweat and overheating—whether you're weaving through city traffic, riding for hours, or pushing the limits on the track.

Flexibility

Motorcycle gear should move with you, not against you. RE ZRO’s advanced TPE ensures flexibility without compromising protection, allowing for natural movement and responsiveness. Whether adjusting your position mid-turn or maneuvering in tight spaces, it adapts seamlessly while maintaining high-impact resistance.

RE ZRO’s intelligent materials and design promote a full range of motion while remaining protective. Engineered to perform across a wide range of temperatures, it stays comfortable and reliable in different riding conditions.

With RE ZRO®, you get protection that works with your body, delivering unrestricted movement and all-day comfort on every ride.
