Rider-informed FAQs
How should this jacket fit?
Riders generally get the best result from a close, comfortable fit that keeps the shoulder and elbow armor centered without restricting reach. Measure over the layers you expect to wear.
Is it suitable for every season?
Its useful temperature range depends on the installed liner, vents, and base layers. Match the setup to the forecast and carry dedicated rain protection for sustained severe weather unless the specifications explicitly state otherwise.
Can the back protection be upgraded?
Where the specifications list a removable PE back pad, it is designed to be replaceable with compatible upgraded armor; confirm the protector size before ordering.
