The RST Race Dept D3O Back Protector with strap system was developed for riders who want to add an extra level of safety to their Leather Suit or their racing suit. Especially when riding in a sporty manner—on the race track or during demanding street rides—a high-quality motorcycle Back Protector is a crucial component of modern protective gear.
This model was designed to be worn under any RST Leather Suit without an airbag system. This makes it the ideal solution for anyone looking to deliberately expand their protection without needing fixed integration into the suit.
D3O Level 2 protection for high safety requirements
At the center is the proven D3O Back Protector technology. The protector is equipped with D3O Level 2 back protection and is aimed at riders who want a high level of protection from their gear. D3O is known for the combination of flexibility, wearing comfort, and strong impact damping—exactly the properties that matter in everyday riding and on the track.
In addition, the protector features memory foam protection in the shin area, which complements the safety concept in a meaningful way and provides an extra boost especially in the lower back area.
Wearable under the suit and built for performance
The main advantage of this model lies in its construction as a Back Protector with a strap system. This allows the protector to sit securely on the body independently of the jacket or suit, and it can be worn specifically under an RST Leather Suit without an airbag.
For many riders, this is particularly important: an Back Protector you can strap on that sits securely, can be worn in a sporty fit, and won’t shift thanks to the fit. This is a real advantage especially in the race track environment or with close-fitting leather racing suits.
Comfortable fit thanks to an adjustable strap system
So that a Back Protector not only protects, but also delivers on the bike, it needs to sit correctly. That’s why the RST Race Dept D3O Back Protector is equipped with adjustable shoulder straps and a double hip closure. This allows you to tailor the fit individually, keeping the protector exactly where it belongs.
The TPR pull tabs additionally make handling easier and support quick, straightforward adjustment. This makes the protector especially interesting for riders who value functionality and suitability for everyday use.
Breathable materials for longer comfort
Comfort while wearing was considered as well. The outer material made of 3D mesh / mesh fabric supports ventilation and helps you wear the protector comfortably even over longer periods. This is especially important under a close-fitting Leather Suit, because good protection doesn’t have to automatically be uncomfortable.
This is how a motorcycle Back Protector for men is created that intelligently combines protection, stability and comfort in a sporty setup.
