Alpinestars - S-M3 Solid Helmet

The S-M3 Solid Helmet is built for riders who want a modern off-road helmet with serious protection and a clean, aggressive look.

Description: 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. Features: Advanced Shell Construction: This helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and lightweight.

Why We Like It

We like this helmet because it feels secure without being overly heavy, and the venting actually works when you’re charging hard.

Why It’ll Work for You

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

  • Advanced Shell Construction: This helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and lightweight. The SM3 medium weighs 1430g (ECE) and 1460g (DOT).
  • 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.
  • The inner and outer surfaces are engineered to minimize the effects of oblique impacts.
  • 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.
  • Alpinestars has introduced a new in-house standard for the SM3 helmet to test the helmet’s chin to conditions heavier than the homologation standard, and in order to pass the Alpinestars’ new standards, the shell thickness and the structure of the helmet design itself have both been optimized on the chin area for superior impact performance.
  • The inner and outer surfaces are engineered to minimize the effects of oblique impacts.
  • Equipped with an EUPDATEncy 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.

Lint free, strong, not super absorbent
Size: 100 Count (Pack of 12), Set name: Classic
These are my preferred cotton rounds. I use them twice daily with micellar water to clean my face. There’s no lint, ever, unlike what I grabbed when I ran out once from the drugstore. The edges aren’t pressed to the point they’re abrasive, which I’ve encountered in other brands and is very frustrating. They’re just the right amount of thick - easy to fold to a corner for running along my lower lash line to get makeup off fully, but not so thin they fall apart as you use them. Both sides are equally soft and durable, and using one side doesn’t compromise the integrity of the other. Once one side is dirty, just flip it over! I ordered the bulk pack to drop the cost per round to $0.02/per, since I know I love these and will go through them constantly. This is a great value. I’ve used the same brand’s organic rounds, which are comparable in quality, thickness, softness, and durability, so if organic matters to you but you’re dubious that the cost could be so close while not sacrificing quality, you can be confident that Cliganic isn’t guilty of shrinkflation to cut costs on what should be a comparable yet more eco-premium experience. Thanks, Cliganic, for making a perfect product!

Great Clean Alternative to Traditional Mouthwash, LOVE this!!
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
I’ve been really impressed with these Boka mouthwash tablets. They’re fluoride‑free and alcohol‑free, which is exactly what I was looking for, and the hydroxyapatite is a nice bonus for supporting enamel without the harshness of traditional mouthwashes. The tablets dissolve easily, the flavor is refreshing without being overpowering, and there’s no burning sensation at all. Do NOT chew and swallow like I did the first time. Chew, get salva going and swish. My teeth never felt so clean!!! I also love that they’re travel‑friendly and cut down on plastic waste compared to big bottles. My breath feels fresh, and my mouth feels clean without that chemical aftertaste. If you’re trying to switch to a cleaner, gentler oral‑care routine, these are a great option.

Tasty, effective, and helpful against thrush
Flavor Name: Citrus Mint, Size: 3.5 Ounce (Pack of 1)
This is a good plastic-free, portable form of mouthwash. Pop one or two tablets in your mouth, chew well, add a little water if your mouth is particularly dry (mine is), swish, and spit. That's it. They don't burn like regular mouthwash, and they leave a nice flavor that isn't overpowering and that lasts longer than other mouthwashes have for me. It's a balanced flavor, if that means anything to you - basically, my mouth somehow feels right afterwards. I was skeptical about the claim that these improve the mouth microbiome, but they've virtually eliminated the thick white layer (presumably thrush) that I've been fighting to clear off my tongue forever. So, yeah, these are definitely a winner.

More like a mint candy than mouthwash.
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
Hard to describe this product. Does it work like your typical mouthwash? No. Does it leave your mouth feeling minty and fresh? Yes, to a certain extent. Would I consider this an alternative to mouthwash on a consistent basis? No, it's ok for traveling because it's easy to transport. When you chew this tablet, it has the texture and feel of a traditional mint. It's chalky and breaks up easily.
