Gilbert uses three named surface patterns across specific ball models: standard pimple, triangular TRI and Multi-Matrix. World Rugby Law 2 allows a ball to be treated to make it easier to grip but does not name these patterns.
Grip-pattern names are useful when comparing a maker’s specific models, but they are not a universal rugby-ball grading system. World Rugby Law 2 says a ball may be treated to make it easier to grip; it does not define TRI, Multi-Matrix or a standard pimple pattern.
Gilbert’s published pattern and model pairings
| Gilbert pattern | Models the maker identifies |
|---|---|
| Standard pimple | Barbarian 2.0, Atom and Omega match balls; Gilbert describes this as a pimple surface. |
| TRI, or triangular | The G-TR 4000 training ball; Gilbert calls its triangular grip pattern patented and exclusive to that model. |
| Multi-Matrix | Sirius and Kinetica match balls; Gilbert describes this as its patented grip pattern. |
These labels describe Gilbert products only. They do not establish that one texture is better for every player or that a ball meets a particular competition’s equipment requirements. Check the exact model, assigned size and organizer’s rules. For the broader range decision, see rugby match balls vs training balls; for age-grade sizing, use the rugby ball-size guide. To keep a ball at its maker’s recommended pressure, see rugby ball pumps and pressure gauges. Browse rugby balls.

Which Gilbert rugby balls have Multi-Matrix grip?
Gilbert names its Sirius and Kinetica match balls as models using Multi-Matrix grip. Check the exact product listing because model details may change.
Does a named grip pattern tell me which rugby ball to buy?
