Review: Great helmet for the price. - Awesome helmet. But heads up! This helmet is not PURE black like the picture makes it look. In the sunlight it is a very very dark grey with the visor only being pure black. It pretty much looks black though. Very hard to tell but the pictures here do make it appear to be totally black in color. Very comfortable helmet, and hey … it’s Alpine Stars. Not much more to say. Dope helmet
Review: Very light weight and comfort - Best investment really nice helmet very light

## Features

- Lightweight outer shell made from impact resistant thermoplastic in three anatomical shell sizes, plus three individual EPS inner liner sizes with a combination of inner lining and cheek padding to offer 6 unique sizes and to ensure the best fitment and protection.
- An engineered raised area with padding effectively reduces the forces transmitted to the collarbone and a patented visor release system that ensures the visor is released with the correct pre-determined amount of force, irrespective of the angle of impact.
- Redesigned chin bar’s new profile, where the base area has been specifically sculpted to give a relief section, raised to clear the collarbone, with a new softer EPS liner which extends beyond the helmet shell itself, and is covered by a more flexible rubber compound providing a reduced chance of any sort of collarbone injury.
- Maximized ventilation and high levels of heat transfer exchange thanks to multi-air inlets and exhaust ports
- Complies with Federal Motor Vehicle Safety Standard 218 (FMVSS 218). The SM5 conforms to ECE R 22.06.

### ⭐⭐⭐⭐⭐ Quality stuff
*by B***L on May 19, 2025*

The s-m5 series is a greater starter helmet for this looking for the best quality helmets. I upgraded to the S-m10 super tech helmet from Alpinestars and yes it is worth the upgrade. But, if you don’t require carbon fiber for safety, I recommend this bad boy. The red color got me several compliments.
