Alpinestars - Stella Plasma Roost Guard
The Stella Plasma Roost Guard is built to give your upper body serious coverage without turning your setup into a bulky suit of armor.
Built to shred, shaped for you—this isn’t just a roost guard, it’s a revolution in female-specific protection. The Alpinestars is engineered from the ground up for women who charge hard off-road.
Why We Like It
We like how it disappears under a jersey while still offering confidence when the roost and rocks start flying.
Why It’ll Work for You
If you want one piece that works for track days and off-road loops, this protector has the coverage to back you up.
Variants / Options
Available in multiple sizes and sometimes youth options so riders of different builds can get dialed protection.
Key Features
- Highly Comfortable — The Nucleon Plasma chest and back protectors are constructed from a USDA Biobased viscoelastic material, which is molded into a structure that is pliable in all directions while maintaining the ability to dissipate impact energy
- The main chassis is engineered with a sports bra ergonomic shape, and is constructed from a soft tactile highly breathable stretch mesh fabric for optimized support and cooling performance
- Side zipper for practicality and comfort
- Extended Coverage — Features Plasma abdominal padding for additional roost coverage
- Adjustable Fit — The perforated V-Belt System ensures a customizable and secure fit
- Lightweight Protection — Features removable Nucleon Plasma Back and Chest Protectors for quick and easy washing of the chassis
- Anatomically engineered for an optimized female performance fit
