ILM WS901 Off-Road Dirt Bike Helmet 4-in-1 Kit (Black White, L) — DOT Certified, Tinted Goggles

The ILM WS901 is a DOT-certified off-road motorcycle helmet that ships as a complete 4-in-1 riding kit—helmet, tinted goggles, gloves, and a balaclava—for dependable protection and all-day comfort.

Designed for motocross, ATV, and dirt riding, the WS901 pairs full-face impact protection with active ventilation and a washable, ergonomic liner. The package includes accessories tuned for dusty, sunny, and high-speed conditions so you can ride with fewer stops and better visibility. Sizes span from Small through 2XL to match a broad range of adult head circumferences.

How does the ILM WS901 protect me on trails and tracks?

The WS901 meets DOT/FMVSS 218 safety requirements and uses a full-coverage shell to shield your head during off-road impacts. The helmet's chinbar and integrated visor help block debris while the included goggles guard your eyes from dust and glare.

• Certified to DOT/FMVSS 218 standards for road and off-road use
• Full-face shell with a protective chinbar for impact coverage
• Tinted goggles included to reduce glare and prevent eye irritation
• Face mask/balaclava adds dust and wind protection for lower face

What comfort features keep the WS901 usable all day?

Comfort comes from a 3D-cut, breathable liner that hugs the head without excessive pressure. The liner is fully removable and washable to stay fresh after repeated rides, and vents are positioned to maintain airflow during strenuous or hot-weather rides.

• Detachable liner for easy cleaning between rides
• Multiple intake and exhaust vents for continuous cooling

What accessories come with the helmet and how do they help?

The WS901 arrives as a 4-in-1 kit that includes a pair of riding gloves, a balaclava mask, and tinted goggles—each chosen to enhance safety and convenience. Together they provide a ready-to-ride solution for protection against wind, dust, and bright conditions.

• Tinted goggles for glare control and debris protection
• Lightweight riding gloves for grip and hand protection
• Balaclava mask for wind and dust barrier under the helmet
• Adjustable visor knob to fine-tune sun blockage while riding
