ILM Dirt Bike Helmet WS901 — Black/White XL, DOT-Certified 4-in-1 Set with Goggles Gloves Mask

The ILM WS901 is a DOT-certified adult off-road motocross helmet sold as a 4-in-1 set—helmet, tinted goggles, gloves, and a balaclava—designed to protect, ventilate, and stay comfortable on long trail rides.

This ILM WS901 package combines certified impact protection with practical accessories to help riders tackle dirt tracks, trails, and ATV runs. Built to meet DOT / FMVSS 218 safety standards, the helmet arrives in multiple adult sizes from S to 2XL and features a removable, washable liner, an adjustable sun visor, and an airflow system engineered for active use. The included goggles, gloves, and face mask reduce dust, wind, and glare so you can focus on control and visibility.

How does the WS901 helmet keep you safe on trails?

The WS901 shell is built to comply with DOT/FMVS 218 safety requirements and to fit a wide range of adult head sizes. The helmet’s structure disperses impact forces while the firm chin strap secures fit during aggressive riding. The full-face design also shields your face from branches, stones, and windblown debris.

• Meets DOT/FMVS 218 certification for road and off-road impact standards
• Full-face shell for facial and cranial protection
• Secure retention system to maintain helmet position under load
• Available sizes S–2XL to match head circumference

What comfort features help during long rides?

Comfort focuses on a three-dimensional, breathable liner that conforms to your head and is fully removable for washing. The internal padding and ergonomic cut reduce pressure points while the adjustable visor and vents reduce heat build-up so you stay cooler on extended runs.

• Detachable, washable inner liner for hygiene and fit tuning
• 3D-cut padding contours to head shape for even pressure distribution
• Multiple intake and exhaust vents for continuous airflow
• Top knob adjusts visor angle to manage sun and glare

What accessories come with the helmet and why do they matter?

The WS901 ships as a practical 4-in-1 kit: tinted goggles reduce glare and shield eyes from debris, gloves improve grip and abrasion resistance, and a balaclava blocks dust while adding a moisture-wicking layer. Each accessory targets a specific riding need so you arrive prepared without buying extras.

• Tinted goggles included to cut glare and keep out dirt
• Motorcycle gloves to improve throttle/brake control and protect hands
• Balaclava face mask for wind protection and sweat management
• Everything sized for adult riders and bundled for convenience

How should I choose the right size and fit?

Measure your head circumference across the widest part, just above the eyebrows, and match it to ILM’s size chart for correct fit. A helmet should sit snugly without pinching; you want firm contact across the cheeks and crown but still be able to open your mouth comfortably.

• Measure head: S (550–560 mm), M (570–580 mm), L (590–600 mm), XL (610–620 mm), 2XL (630–640 mm)
• Try helmet with goggles and balaclava to check real-world fit
• Adjust chin strap so two fingers fit between strap and jaw
• Replace helmet after significant impact or visible damage

Who this is for: The ILM WS901 set is aimed at recreational and dedicated off-road riders who want a ready-to-ride kit with certified protection, ventilation, and integrated accessories. It’s suited for motocross enthusiasts, ATV and UTV users, trail riders, and anyone who prefers a bundled solution that covers eye protection, face coverage, and hand protection alongside a DOT-rated helmet. Choose your size to match head circumference, and use the removable liner and vents to dial in comfort for heat or cold conditions.
