-- FREQUENTLY ASKED QUESTIONS --
Question 1
Yes, this riding suit is designed for winter track days. It uses top-grain cowhide leather 1.2 to 1.3 mm thick. Accordion stretch panels at the back and knees boost flexibility. Cordura stretch panels at sleeves, crotch, and calf enhance mobility. Pre-curved sleeves help you ride in a natural, locked-in position. External CE-approved protectors guard shoulders, elbows, and knees. Removable dual-density armor and spine protector add optional impact protection. Soft neoprene cuffs and collar reduce abrasion and chafing. For winter riders, warmth comes from a compatible base layer and ventilation. Pair it with proper armor care and seasonal maintenance for longevity.
Question 2
Yes, it offers robust CE armor with external protection on key joints. Armor is mounted externally at shoulders, elbows, and knees for impact distribution. Removable dual-density armor lets you customize stiffness and fit. A removable spine protector adds back protection and confidence during rides. Compared to basic race gear, this setup offers more modularity. External armor remains accessible for inspection and replacement as needed. The strong seams and reinforced overlays support armor integrity during slides. These features suit serious track riders who want upgrade options. Note safety claims depend on riding conditions and maintenance.
Question 3
Start with your size based on precise measurements rather than feeling. Measure chest at the fullest point, waist at the natural waist. Height and inseam influence leg length and knee armor alignment. Use the size chart and consider armor layering inside. Pre-curved sleeves reduce the need for immediate adjustments. Velcro closures at neck, cuffs, and calf help fine-tuning. If unsure between sizes, choose the larger for comfort and movement. Remember armor is removable, so fit over expected protective gear. We recommend checking the return policy if the fit isn't right. This helps ensure safety and confidence during critical miles.
Question 4
Yes, most protective components are removable for care and setup. Knee sliders detach with Velcro tabs and standard fasteners. Shoulder and elbow armor slides out for inspection or upgrades. The spine protector and knee armor are likewise removable. Reinsert armor with care and follow the manufacturer’s guidance. Optional aerodynamic hump can be swapped or omitted depending on setup. Note that zippers, seams, and overlays remain intact during removal. For maintenance, wipe clean and let dry before reassembly. If unsure, contact support for compatibility and proper reinstallation. This approach keeps the suit versatile for custom setups.
Question 5
Yes, the optional hump is designed to improve aerodynamics. It also adds a bit of neck protection by shaping airflow. The hump is removable, so you can tailor the setup. Riders who chase faster laps often prefer reduced drag. Keep in mind comfort, size, and venting when deciding. The hump doesn’t replace armor and should complement existing protections. For winter riding, it’s one option among many customization choices. Consider trial fitting to assess comfort and balance on the bike. Always verify compatibility with the suit’s shell and seams. If unsure, ask support for guidance on neck hump usage.
