Alpinestars - SM8 Radium 2 Helmet

The S-M8’s design is coherent to Alpinestars philosophy and shares distinctive themes with other products in the portfolio; a smooth, attractive, profile which is streamlined and free of any external channels and features that might act as a load point in an impact, or compromise the overall integrity of the construction. The surface curvature promotes reduced friction on impact, allowing deflection and the most efficient transfer of energy to protect the rider’s head from direct force to the skull and referred to the neck and spinal column. The aperture is designed to accommodate a wide variety of goggles and the air vents in the shell are located to maximize ventilation efficiency.

Features: 

  • The S-M8 shell has been profiled with performance as a priority and with a design style that identifies the profile of the helmet and its sculpted surface as uniquely ‘Alpinestars’.
  • Another key feature is the S-M8 shell sizeng solution; each helmet fit size has its own appropriate shell size to deliver the most anatomical solution for the wide variety of fit needs worldwide.
  • The helmet’s shell construction utilizes a highly advanced molding technology with a multi-composite combination: Carbon, high density carbon outer layer that improves strength and efficiency of energy dissipation over the shell.
  • Uni-directional carbon composite layer that gives significantly greater radial strength around the shell, preventing compression but allowing controlled deflection for reducing transmitted impact energy.
  • Aramid fiber layer which provides critical penetration protection.
  • This combination of layers is given even greater performance with an epoxy resin bonding that offers the best possible strength and energy management; limited outer shell deflection means the energy spreads wider and is better absorbed by the EPS liner.
  • The result of the unique shell lay-up process employed in the S-M8 construction results in extremely effective impact protection. With a fully equipped helmet testing facility, within Alpinestars Racing Development Center, an exhaustive impact research program has resulted in the Supertech M8 returning linear and oblique impact performance which far improves upon current helmet regulation standard limits. For direct, linear, impact by an average magnitude of 41% and for rotational acceleration, oblique, impact performance by an average of 48%.

Perfect for tight spaces and surprisingly sturdy!
Color: White, Size: 6 Tier(13 inches)
I am beyond impressed with this 6-tier storage cart. I was looking for something to maximize the vertical space in a very narrow gap, and this fits like it was custom-made. What I love: Quality & Durability: The carbon steel frame feels very stable, and the safety stops on the drawers are a game-changer—you don’t have to worry about the baskets falling out when you pull them. Design & Aesthetics: The wood top gives it a premium look that blends nicely with my decor, unlike all-plastic utility carts. The white finish is clean and bright. Ease of Use: Assembly was straightforward, and it rolls smoothly even when fully loaded. I also appreciate the 6 side hooks for hanging smaller items. Versatility: The drainage holes in the baskets make it great for the bathroom or laundry room, but it’s cute enough for a craft room or kitchen too. If you have a small space that needs serious organization, this is definitely worth the investment. It’s functional, high-quality, and looks great!

A great product!
Color: Black, Size: 6 Tier(8 inches), Color: Black, Size: 6 Tier(8 inches)
This storage cart really maximizes the space going up. This rolling cart is taller than me; I have 8-foot-tall doors, and you can see from my picture how tall this is. It is lightweight, rolls smoothly, is easy to assemble, and is a great value. You can place heavier or taller shampoo bottles on the shelves; they are pretty steady and not loose. The way this is built, the shelves are sturdy (they have 2 metal poles underneath giving them support). They also don't slide all the way out, so you don't have to worry about pulling it out too far and having things fall. This is a really great product, and I plan to use it in my master bathroom for all the extra stuff we have.

Great value!
Color: Ink Black, Size: 2 pack
Really sturdy and a great value for the money. Almost idiot proof when putting it together, too. The drawing is very specific, and everything is really well marked and numbered. This isn’t fine furniture, but it really is a great value for the money!
