Knox Micro-Lock Air MK2 Back Protector | Unisex | Black | KNXAMLAirV2Back

Wearing back protection all day should never feel like a compromise — and with the Knox Micro-Lock Air MK2, it doesn't. Engineered for riders who demand EN 1621-2:2014 Level 2 certification without bulk or heat build-up, this unisex protector wraps around your spine from the morning commute to an evening sport run, staying so comfortable you forget it's there until the moment you need it most.

Key Features

• Micro-Lock material stays soft and pliable during normal riding, then stiffens on impact to absorb and dissipate energy — no pre-hardened armour stiffness
• Certified EN 1621-2:2014 Level 2 for the highest standard of back impact protection
• Air channels combined with premium spacer fabric deliver multi-directional airflow to keep your back cool on long days
• Double waist-belt system with adjustable positioning and quick-release shoulder straps — also wearable crossed — hold the protector exactly in place even during spirited riding
• Removable lumbar panel included for additional lower-back coverage
• Outer shell is removable and machine washable for effortless long-term maintenance

All-Day Comfort by Design

The MK2 generation brings meaningful ergonomic refinements over its predecessor. The revised fit system pairs a dual waist-belt harness with quick-release shoulder straps that can be worn straight or crossed depending on your build and riding position. Adjustable panel positioning means you can dial the protector precisely to your torso length, so it sits correctly whether you're upright on the motorway or tucked on a sport bike. The low-profile, body-hugging silhouette adds virtually nothing to the sensation of wearing a jacket or riding shirt, and the unisex cut suits both male and female riders equally well in sizes S and L.

Micro-Lock Technology Explained

Knox developed Micro-Lock as a next-generation alternative to conventional rigid or foam armour. At rest, the material flexes freely with your body, making it genuinely comfortable to put on and wear through a full day's riding. On impact, the molecular structure reacts immediately to lock and stiffen, redirecting and absorbing kinetic energy before it reaches the spine. The residual energy transmitted to the rider is dramatically reduced — and this performance is independently verified to EN 1621-2:2014 Level 2, the highest level in the European back-protector standard. Designed and manufactured in Great Britain, Micro-Lock reflects Knox's decades of specialist armour expertise.

Superior Ventilation for Extended Use

The "Air" designation in the name is earned. Integrated air channels guide airflow across the back panel in multiple directions, working in tandem with high-grade spacer fabric — an open-knit, three-dimensional mesh construction — to keep warm air moving away from your back. Whether you're touring through summer heat or riding to work on a mild day, the Micro-Lock Air MK2 remains comfortable wear after wear without becoming clammy or restrictive.

Modular and Easy to Maintain

The outer shell detaches cleanly from the armour core, allowing machine washing to keep the protector fresh and hygienic. The armour itself should not be immersed in water — air drying is recommended. For riders wanting comprehensive upper-body coverage, the Micro-Lock Air MK2 is optionally compatible with the Knox Micro-Lock chest protector, making it straightforward to build a full front-and-back protection system.

Fitment and Compatibility

The Knox Micro-Lock Air MK2 back protector is a standalone wearable protector intended for use with any motorcycle jacket or riding shirt that accommodates a CE back-protector insert, or worn independently beneath outer garments. Available in sizes S and L with a unisex fit suitable for all riders. Intended use: sport road riding, everyday commuting, and touring.
