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%.

Not bad at all!
These headlight cleaner wipes worked far better than I thought they would. I have used many a headlight cleaner and restorer, but this kit was the easiest to use with very good results. No need for power tools or even different sanding disks. Just two different types of wipes, super easy. We will see how long the lights stay clear for, but if I had to do it once a year it would be worth it! Four stars because the lights came out clear, but not crystal clear, but to be fair that may just be the condition of my headlights. Try this least expensive, easy fix first. It many very well be just what you need.

Worth it for $12.
Three stars for the progress it made on the lights of our 9 year old car. It works, but it won't look like new. Requires a bit of elbow grease, and it feels like a waste when the wipes run dry pretty fast. You have to keep them folded small (per the instructions) so they don't evaporate too fast, but then you get a tiny cleaning surface area as well. Spoiler alert: They still dry out fast. I wish I'd taken pictures for you because you WILL see a good improvement. Just don't expect brand new look. I'd say we had a maybe 75% improvement, and that combined with the new headlamps we installed made them work great. 4 stars if they want to come back and offer a like 2-4oz bottle of the chemical they use on the wipes and just let me use my own microfiber. That would be great.

Product doesn't work as advertised
This product does not provide enough wipes to remove more than the minimum amount of oxidation. The headlights were starting to yellow, so the oxidation was not severe. We followed the directions on the box to the letter and after using the wipes as directed were left with a sticky residue (which was left-over oxidation that the drying wipes could not remove). I am forced to purchase another box of the product in order to complete the job. I can't drive my car around with the tape protecting the body of the car on it, plus this is Florida so there would be bugs stuck in the tape and the sticky residue. A terrible product. Plus when I called them they said they would send me an email so I can tell them what the problem is and they would give it to their "research" staff to handle. I'm doing that and perhaps they will reimburse me for the second box I will have to get overnighted in order to finish the job.

Armor All Car Headlight Cleaner Wipes – Quick & Easy Clarity
The Armor All Car Headlight Cleaner Wipes are a convenient and effective solution for restoring foggy, yellowed, or hazy headlights without the need for complicated kits. These pre-moistened wipes make it super easy to wipe away oxidation and dirt, improving visibility and enhancing the car’s overall appearance. ✅ Pros: Quick & Easy to Use: No need for additional tools or sanding. Restores Clarity: Helps reduce haze and oxidation buildup. Convenient Packaging: Portable and easy to store in the car. No Harsh Chemicals or Strong Odors. ⚠️ Cons: May Require Multiple Uses for Heavily Oxidized Headlights. Not a Permanent Fix: Works best for maintenance but may not fully restore very cloudy headlights. Can Leave a Slight Residue: Needs buffing for the best shine. Final Verdict: For a quick fix and easy maintenance, the Armor All Headlight Cleaner Wipes are a great go-to option. They work well for light oxidation and keeping headlights clear, but for severely foggy lights, a full restoration kit may be needed. Great for touch-ups and convenience

Foggy foggy to crystal clear in less than an hour!!! True story!
Pleasantly surprised at a)how easy this kit was to use, b) the results of the kit and I highly recommend this kit. Took my headlights from completely foggy to crystal clear as if they were brand new. Only took about 30 minutes with a little elbow grease. Great product at a great price!
