Frequently asked questions Hide FAQs
What does J22-compatible mean for these protectors?
J22 is a compatibility code used for protector inserts shaped to fit specific Alpinestars garments. In this collection, the focus is on armor designed for jackets, suits, or protective layers that use the J22 pocket format rather than on universal inserts.
This matters because impact protectors need to sit flat, stay centered, and cover the intended zone while riding. If your garment specifies J22 compatibility, choosing from this collection helps maintain the original fit and positioning the garment was designed around.
How do I know if my jacket or suit needs a J22 protector insert?
Check the garment label, product page, or original technical information for the required protector code and protection zone. The compatibility code is the key reference because inserts that look similar can still differ in shape, thickness, and pocket fit.
If your garment lists J22, this collection is the correct starting point. If you need to compare other armor formats or body-zone options, you can also explore motorcycle protectors and the broader motorcycle protection range.
Are J22-compatible protectors CE certified, and which standards apply?
Many J22-compatible inserts are CE-certified, but the exact certification depends on the impact zone. As a general guide, shoulder, elbow, hip, and knee protectors typically refer to EN 1621-1, back protectors to EN 1621-2, and chest protectors to EN 1621-3.
J22 identifies fit and pocket compatibility, not the certification level by itself. Always check the individual product page and labeling to confirm the exact CE standard and whether the insert is Level 1 or Level 2.
Can I use J22-compatible protectors with a Tech-Air airbag system?
Sometimes, but it depends on the jacket or suit and on the specific Tech-Air® system. Airbag garments can have their own fit, clearance, and armor requirements, so riders should not assume that every passive insert should remain installed when using an airbag setup.
The safest approach is to confirm the garment through the Tech-Air® compatibility checker and follow the instructions provided for that exact garment and system combination.
How should I install, care for, and replace J22 protector inserts?
Insert the protector into the dedicated internal pocket in the correct orientation, then check that it lies flat without folding or bunching. Once the garment is on, the protector should stay aligned with the intended impact zone in a normal riding position.
For care, remove inserts before washing the garment unless the care label states otherwise. Clean the protector with a damp cloth, let it air dry away from direct heat, and replace it if it shows cracks, permanent deformation, or visible impact damage.
