HELMET FEATURES

Anatomically engineered and profiled specifically for youth and younger riders, the all-new SM3 Youth Helmet is optimized for MX, Enduro and Off-road use, and features a whole raft of technologies and innovations taken from Alpinestars range of adult helmets to deliver the optimal blend of performance, protection and comfort.

  • This lightweight 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 light weight.

  • Lightweight outer shell is constructed from a technologically advanced impact resistant thermoplastic in three sizes (Youth Small, Youth Medium and Youth Large. The SM3 Youth weighs 1060g (ECE) and 1170g (DOT).
  • Separate versions of the shells for DOT and ECE requirements; the DOT certified version of the helmet’s inner shell is constructed with a composite fiber assembled between the outer shell and the EPS liner for maximum protection against impacts.
  • The fit can be tailored to the rider’s head thanks to the helmet’s crown and cheek pads, which are available as spare parts in different thicknesses.
  • Youth Medium (YM) and Youth Large (YL) sizes share the same EPS size, which allows riders with an YM size to initially buy an YM helmet and then configure it to a Youth Large size as they grow via the crown and cheek pad spare parts.
  • The Youth Small (YS) has a smaller EPS size and can be customized only via the cheek pads. Alpinestars extensive research has shown that the kids that wear a YS size are very small, typically 3 to 4 years old, and therefore they require a dedicated helmet fit.
  • The multiple density inner liner ensures the helmet is equipped with the correct density in the correct area for enhanced impact absorption, while also helping to reduce overall weight.

  • The inner and outer surfaces are engineered to minimize the effects of oblique impacts.
  • 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.
  • Maximized ventilation and high levels of heat transfer exchange thanks to 10 inlets and seven exhaust ports.
  • The visor has been designed to direct air into the ports for enhanced airflow.
  • 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.
  • Comfort liner is constructed using recycled materials for a lower carbon footprint.
  • Hydration tube channels are integrated into the helmet’s cheek pads for convenience and performance.
  • Soft textile chin strap is 25mm for optimal safety and rider comfort.
  • ALPINESTARS NEW SAFETY STANDARD Alpinestars has introduced a new in-house standard for the SM3 Youth 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 in the chin area for superior impact performance.

  • 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.
  • 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.

Mom of 3 recommend!
Size: 5T-6T, Unit Count: 14
I'm using these again for the 3rd time and they're great as always. My 3rd is still having some issues at night time with bed wetting, and as they get older the bigger the mess, so these truly hold up to a full bladder. And they don't smell by morning like some diaper brands. I'm usually against pull ups, but these are great for up and down ease of use and that added protection when it comes to potty training. I love the bigger size inclusion for larger children which we struggle with for comfort compared to other brands.

Approved by an Overnight Registered Nurse, Has worked great last 4 years!
Item Package Quantity: 1, Size: 100 Count (Pack of 1)
I have worked overnight as a Registered Nurse for the last 4 of 6 years and I will offer my own experience on how these pills have helped me in my job performance. To start of with I have to say that no two human beings are the same so before I bought these pills I read the good and bad reviews and wasn't sure on the product. I've had heart palpitations in the past from excess caffeine when I drank one of the blue pop top Rock Stars with 1.5 times the caffeine as regular Rock Star and I can say that no, it's not fun at all. I've also experienced when I drink to much caffeine at once and find myself either visiting the restroom many times during a shift, or the crash that comes after the initial burst of energy. Anyways, I can say that with ONE pill a shift prior to going to work, I am able to stay awake and not in a forceful manner without the many negative effects from caffeine that I've experienced in the past. Working night shifts, I've seen how many co-workers need to chain drink coffee all night. I can't say that I don't like coffee, but I don't drink it more than once a week and I prefer not too if I have the chance. This is why I am glad that the Guarana Energizer has worked for me. I am able to be more alert all shift long, not have to struggle with energy or struggle with staying awake, and when I get home I not too wired where I have a hard time going to sleep. On my days off it also works as an excellent energy booster for the mornings to get your energy level going for your day ahead. Also, I've tried other guarana pills when the Source Naturals were no longer in stock (same 900 mg strength), and I have to say that I had to take more than 2 pills per shift to keep me awake, plus they never lasted a full shift. Don't know why the "energizer" term makes a difference, but it does for me. I recommend it to all my co-workers, and when they feel low on energy I've seen that even 1/2 a tab is sufficient for a little pick me up especially for those sensitive to caffeine.

The best guarana I've used - helped me kick energy drinks!
Item Package Quantity: 1, Size: 100 Count (Pack of 1)
I suppose I ought to stand in front of a group of people, and admit to being a caffeine addict. However, I rather like caffeine. I started in on caffeine at an early age- first by drinking soda- mostly cola- as often as my parents would allow. As a teenager, I discovered coffee. Later, it was espresso drinks- I loved a good quad-shot latte, and eventually was getting several a day. A few years ago, my stomach stopped agreeing with coffee as much, so I switched to energy drinks. I was drinking about 4 Rockstars a day. After doing the math, I realized that I was spending around $300 a month on these silly beverages. To economize, I switched to No-Doz. However, it wasn't the same, and it honestly felt... unnatural. The No-Doz sometimes aggravated my stomach, and I just didn't feel as well. Then I tried Guarana, as it is one of the main functional ingredients in many energy drinks. Love it. It seems to last a bit longer (it could be my imagination there, I am unsure), and it definitely feels more natural. I take a few of these per day- and I seem to have less of a "caffeine crash" after 4 hours or so than I once did. It still happens, but it's more gentle. My only complaint is that the pills are rather large- definitely a chore to swallow! Bottom line- this stuff costs just a bit more than a bottle of No-Doz, and is made from natural stuff. It feels healthier, and probably is. I now spend in a month wha I spent in a day on energy drinks. Also- for what it's worth- I've tried other brands of guarana, and this one "feels" best.

Worked well for a few days, then built up a tolerance
Item Package Quantity: 1, Size: 100 Count (Pack of 1)
Guarana for me is one of those things that you should only take every once and a while. It gave me a nice surge of energy for about an hour or so after taking one, then after only a few mornings of taking one I noticed the effect completely wore off. So I stopped taking it for about a week. Then tried taking it again and it still did nothing. Maybe it's just my body, but now I need at least two to notice any effect. It's not that I even feel more alert now, it just makes me feel like I drank to much coffee. I will finish the bottle and then will not buy it again. Different supplements work differently for everyone though! Just because this didn't work for me longterm, that's not to say it won't work wonderfully for you. Trial and error is key with anything like this.
