Dainese Wave 1S D1 Air Back Protector – Height Below 165 cm | Part 20187609900100

Designed for riders whose torso height sits below 165 cm, the Dainese Wave 1S D1 Air back protector delivers genuine Level 2 protection without the weight or bulk that discourages everyday use. Whether you are commuting through the city or spending hours in the saddle on a long tour, it stays firmly in place and keeps your back cool — protection you will actually want to wear, every ride.

Key Features

• CE Category II certified to EN 1621-2:2014 Level 2 — the highest standard for motorcycle back protectors, suitable for road and track use alike.
• Aluminium honeycomb inner frame combined with Crash Absorb® foam core — absorbs and disperses impact energy efficiently across the entire back panel.
• Perforated, wave-form polypropylene outer shell — maximises structural resilience while allowing continuous airflow through the protector.
• Breathable polyester-mesh inner lining — wicks moisture away from the back, keeping you dry on warm days and extended tours.
• Doubly adjustable lumbar strap plus removable shoulder straps — dial in a precise, stable fit regardless of your jacket or riding position.
• Lumbar joint articulation — allows natural movement without the protector shifting out of position during dynamic riding.

Construction and Materials

The Wave 1S D1 Air is built around a thermoformed dual-density support structure that wraps the torso in a consistent, anatomical curve. The hard polypropylene outer shell is perforated and pressed into a wave profile, a design that simultaneously stiffens the panel against point impacts and opens channels for air to pass through freely. Beneath it, the aluminium honeycomb frame provides a rigid energy-distribution lattice, and the Crash Absorb® foam layer handles the final stage of impact attenuation — together they meet the EN 1621-2:2014 Level 2 threshold without relying on excessive material thickness.

The lumbar strap and harness webbing are constructed from double-jersey fabric, which is soft against the skin and resists deformation after repeated adjustment cycles. The inner lining in breathable polyester mesh sits directly against any base layer, drawing heat and moisture away from the back during sustained effort.

Ergonomics and Fit

A back protector is only effective if it stays in the correct position, which is why Dainese engineered a doubly adjustable lumbar strap into this model. Combined with removable shoulder straps, the Wave 1S D1 Air can be worn as a standalone protector over a base layer or secured into a compatible Dainese jacket. The integrated lumbar joint adds a pivot point at the lower back, so the panel flexes with your body through corners and crouched riding positions rather than riding up or rotating out of alignment.

Ventilation

The perforated outer plates are not merely aesthetic — each opening feeds air directly into the cavity between shell and lining, creating a steady chimney effect that prevents heat build-up on warm days. The polyester-mesh lining complements this by drawing moisture away from the skin, making the Wave 1S D1 Air a genuinely comfortable choice for summer riding and multi-day touring alike.

Fitment and Compatibility

This variant of the Wave 1S D1 Air is specifically sized for riders with a torso height below 165 cm (65 in). It is available in two widths — size M for a back width up to 89 cm (35 in) and size L for a back width of 90 cm (35.4 in) and above — allowing a precise fit across the intended height range. The protector is compatible with Dainese jackets designed to accept a D1-format back protector insert, and it may also be worn independently using the included strap system.

Warranty

The Dainese Wave 1S D1 Air is covered by a 2-year manufacturer warranty in accordance with current Dainese guidelines. The warranty addresses conformity defects and entitles the owner to free repair or replacement parts under the conditions set out by Dainese.
