Dainese Manis D1 G2
The Manis D1 G2 is a premium spine protector celebrated for its ergonomic fit, sophisticated energy-distribution architecture and integration into sport-focused riding kits, producing excellent impact dissipation across the vertebrae. As a back and spine protector it typically carries a price premium over softer, vest-style options, but justifies it with refined materials and a focus on race-derived biomechanics—positioning it as a technical alternative to Alpinestars with slightly different stiffness and fit characteristics. Riders seeking boutique engineering and seamless suit integration often choose the Manis when the budget prioritizes maximal targeted protection.

Knox Aegis Back Protector 7 Plate
The Knox Aegis 7-plate back protector uses an articulated plate system that prioritizes natural spinal movement and robust mechanical protection, providing broad coverage and durability for road and touring riders. In the back and spine protectors category it is often priced attractively relative to race-focused units while delivering a reassuringly solid, ergonomic feel—especially for riders who prefer layered plate protection instead of purely foam-based solutions. Compared to the softer Forcefield or vest-style Icon, the Aegis offers a tactile plate-backed alternative that balances flexibility with a distinctly protective mechanical design.

Icon Field Armor Softcore Vest
The Field Armor Softcore Vest is a lightweight, breathable vest-style protector aimed at urban and warm-weather riders who value ventilation and day-to-day comfort over the maximum attainable impact rating. Within the back and spine protectors segment it represents a budget- and user-friendly option: less bulky and more affordable than many CE Level 2 systems, though it sacrifices some of the high-end impact dissipation you get from Forcefield, Dainese or Alpinestars. It's a sensible choice for riders seeking an inexpensive, comfortable entry-level spine solution or supplementary coverage under casual gear.
