Engineered for MX, Enduro, and off-road riding, the SM3 Helmet integrates advanced technologies and innovations designed to enhance ease of use, comfort, and impact protection.
Key Features
- Ventilation: Maximized ventilation and high levels of heat transfer exchange thanks to 10 inlets and seven exhaust ports.
- Rotational Acceleration Force Protection: Alpinestars patented low-friction coating is applied to the inner part of the main EPS liner to reduce the rotational acceleration forces that can result from certain oblique impacts. This layer essentially acts as a slip plane to mimic the brain’s own low-friction cerebrospinal fluid, which is the body’s natural defense against oblique impacts.
- Visor Release: Patented visor release system ensures the visor is released with the correct pre-determined amount of force, effectively reducing the forces on the rider’s neck during an impact.
Construction
- 5 EPS inner parts with 4 densities to effectively manage volume and impact perfromance.
- Hydration tube channels are integrated into the helmet’s cheek pads for convenience and performance.
- Comfort liner is constructed using recycled materials for a lower carbon footprint.
- The fit can be tailored to the rider’s head thanks to the helmet’s crown and cheek pads, which are available as genuine spare parts in different thicknesses.
Protection
- The inner and outer surfaces are engineered to minimize the effects of oblique impacts.
- Equipped with an Emergency Release System and removable cheek pads to permit the safe and easy removal of the cheek pads while the helmet is still on, while the 3D contoured foam ensures rider comfort.
- Soft textile chin strap is 25mm for optimal safety and rider comfort.
- Stainless steel D-rings ensure a tight and secure fit.
- The SM3 helmet conforms to both DOT certification and ECE 2206 homologation for use worldwide.

Cheap, easily breakable, and barley works
Style: 15W Charger, Style: 15W Charger
First off, it didn’t even come with the charging chord, so I had to order another separately after it came. The product broke the fourth time i used it, the whole thing came apart when i tried taking my phone off. When it was working, it charged maybe 1% every hour. Definitely not the best choice in the category, look at other options

Super stable, strong magnet, fast, charging Tesla screen mount
Style: 15W Charger
This is a great item. It’s adjustable annd attaches firmly and no tape no adhesive. I’ve been using it for several weeks now charges the phone very fast.. The phone has never fallen off of it. Not even close. Highly recommend this item.

Works great, but included cable is too short
Style: 15W Charger
The cable included is only about 3 feet long and has a USB-a plug. Teslas now have only USB-c outlets, so the cable is useless anyway. If the cable were 6’ long and type USB-c, it could be tucked under the molding and hidden. I had to get another cable to complete the installation. I like this mount/charger because it is nondestructive - it doesn’t use tape or glue to install. The magnet is strong and it charges my phone quickly.

Decent but magnet isn’t strong enough
Style: 15W Charger
Unit appears well made and I feel like it minimizes any potential damage to the screen. For me, magnet just wasn’t strong enough and I wasn’t a fan of the cable - would be nice if product had clips for cable management or something to give it a cleaner install. If it wasn’t for the magnet issue, I probably would have kept. Returned.

Really a nice product!
Style: 15W Charger, Style: 15W Charger
I wanted a nice magsafe charge/holder for my phone and I tried this one and so far, it's great.
Pros:
- It has a really nice-looking LED behind the magsafe holder which glows nicely, as you see in the pic.
- The plastic feels good, strong and (hopefully) not plastic that degrades and becomes brittle.
- The rubber bumpers which hold it in place under the mount against your display seem well-placed.
- It's fully adjustable between positions wherever you wish to mount it.
- You can mount your phone either above or to the side of the display on any corner which provides nice flexibility.
- I found it best on the upper right because on the left, the steering wheel obscures the phone and the two bottom corners aren't useful to me.
- The little knobs work well to hold it in place and tighten nicely.
Cons:
- The only problem is how the design has the cable visible and sticking out when it could have easily been designed to integrate into the little arm so it's hidden. As it is, the ugly, out of place and avoidable USB-C cable is visible which I don't like.
- You can rotate the holder to make the USB-C cable appear in front of the arm holder so it's less visible but it should have been avoided with a simple design modification and integrated USB cable for a more streamlined appearance.
In any case, this is a nice addition to my Model 3 Performance to hold my phone while I drive, out of the way while still charging.
Try one.
