Alpinestars - SM5 Solid Helmet
The SM5 Solid Helmet is built for riders who want a modern off-road helmet with serious protection and a clean, aggressive look.
The SM5 helmet has been designed to provide MX riders with a helmet that is safe and purposefully designed to deliver optimal protection and comfort.

If you’re after a helmet that can handle moto days, off-road loops, and everything in between, this one gives you dependable protection and comfort.
Variants / Options
Available in multiple shell sizes and graphics so you can get a confident fit and a look that matches your style.
Key Features
- With a strong outer shell, advanced impact liner, and plenty of venting, it works to manage energy in a crash while keeping air moving around your head.
