G-Form MX360 Impact Shirt

Product Overview

The G-Form MX360 Impact Shirt is a CE 1621-2 certified protective base layer featuring a removable back protector and 360° coverage with SmartFlex impact-absorbing padding. Designed for downhill, enduro, BMX, and motocross, this shirt combines flexible SmartFlex technology that hardens on impact with ventilated multi-density foam for comfort and world-class spinal protection. Machine washable with moisture-wicking mesh fabric and a full-length locking front zipper.

Key Features

• SmartFlex technology – G-Form's proprietary padding remains flexible during normal riding but instantly hardens on impact to absorb and disperse energy, then returns to flexible state
• CE 1621-2 certified back protector – Removable ventilated back pad meets European safety standard for motorcyclist back protectors (Level 2); layers of SmartFlex and multi-density foam provide spinal protection and comfort
• 360° SmartFlex Stretch padding – Shoulder and chest coverage protects against crashes, falls, and roost debris while maintaining flexibility for unrestricted movement
• Removable back pad – Back protector can be taken out for washing, size adjustment, or less aggressive riding situations
• Ventilated design – Perforations and breathable construction prevent overheating during high-output riding
• Machine washable – Entire shirt (with back pad removed) can be machine washed for easy maintenance and hygiene
• Full-length front zipper – Locking zipper with reinforced seams allows easy on/off over other layers and prevents accidental opening
• Moisture-wicking mesh fabric – Breathable base layer material pulls sweat away from skin for comfort during extended sessions

Compatibility and Ideal Use Cases

This impact shirt is designed as a protective base layer worn under jerseys or jackets for downhill mountain biking, enduro racing, BMX racing and freestyle, and motocross. Adult sizing fits riders approximately 5'4" and taller—verify size chart before ordering to ensure proper fit, as armor must be positioned correctly to provide effective protection. The CE 1621-2 certification indicates high-level back protection suitable for aggressive riding and racing where spinal injury risk is elevated. Ideal for riders who need certified protection but want flexibility and comfort compared to hard-shell armor. The removable back pad allows customization—remove it for less intense sessions or keep it in for maximum protection. Best suited for warm to moderate temperatures due to ventilated design; may require additional insulation layers in cold conditions. The SmartFlex technology works across all temperatures and does not become stiff in cold weather like some foam protectors. Machine washability makes this practical for frequent use and multi-day events where hygiene matters. Not a substitute for full chest protectors or roost guards in motocross applications where hard debris impact is common—this shirt focuses on impact absorption rather than abrasion or penetration resistance.
