What does P03-compatible mean for these protectors?
This collection gathers CE-certified armor inserts designed to fit Alpinestars garments that reference the P03 armor pocket specification. Selecting a P03‑compatible insert helps ensure the protector’s shape and dimensions match the pocket geometry for a flat, secure fit.
Check your garment’s inner label or product page for a P03 compatibility note. If you need to browse by protector category instead of pocket code, see our broader protectors collection.
How do I choose the right size insert for a P03-compatible jacket or suit?
Match the insert type (back, chest, shoulder, elbow) and size to your garment size and the indicated P03 pocket. The correct insert should fully seat in the pocket without folding or gapping, maintaining coverage while allowing normal reach and torso rotation.
For back protection, the upper edge should sit between the shoulder blades and the lower edge cover the lumbar area without pushing when seated. If between sizes, prioritize the insert that sits flat and stable over maximum length; refer to the size guidance on the protector’s product page and your garment label.
Which CE standards apply to these inserts, and what’s the difference between Level 1 and Level 2?
Motorcycle impact protectors are tested to EN 1621 standards: EN 1621‑1 for limb armor (shoulder, elbow, hip, knee), EN 1621‑2 for back inserts, and EN 1621‑3 for chest inserts. Labels indicate the applicable standard and performance level.
| CE Level | Impact attenuation | Typical use |
|---|---|---|
| Level 1 | Baseline impact reduction with lighter weight/flexibility. | Urban/everyday riding and hot weather. |
| Level 2 | Higher impact reduction (stricter force limit). | Touring, sport/track, or riders prioritizing protection. |
Can I use P03-compatible inserts with a Tech‑Air airbag system?
Airbags and passive inserts serve different roles. Many Tech‑Air® vests include an integrated back protector and require specific garment clearance. Depending on the setup, you may be instructed to remove a separate back or chest insert to avoid stacking components.
Confirm your pairing using the Tech‑Air® compatibility checker, then explore available systems in Tech‑Air® systems and select any additional limb armor as needed.
How should I install and care for P03-compatible protectors?
Insert the protector in the P03 pocket with the orientation indicated on the label/arrow, ensuring it lies flat and covers the target area without distorting the shell. Close all pocket closures before riding.
Remove all armor inserts before washing a garment. Wipe protectors separately with a damp cloth and mild soap, then air dry away from heat; do not machine wash, wring, or tumble dry protectors. Reinsert only when both garment and inserts are fully dry.
