Question: This this looks great... is it DOT certified?I want on for my motorcycle
Document: I bought this for my 12 year old son who just started snowboarding. I didn't want to spend a fortune, but wanted something that would protect him from his inevitable falls. As the other reviews mentioned the helmet runs small, so I bought the XL for him. It fits perfectly and is made very well. My son finds it comfortable, and likes the way it looks. I am pleased with the protection it allows him while he finds his footing on the slopes.
I'm 46 years old and new to snowboarding. I really don't know if I will continue to snowboard so i didn't want to spend a lot of $$$$ for a nice helmet, so I gave this one a try. First, out of the box, the helmet looks really nice. I got the matt black version. It has a rubbery type feel to it which I think is nice and it keeps your goggles in place when you put them on top (no slipping).
I wanted to get a new helmet but didnt want to spend alot. This is a very nice helmet and the price was great! totally worth it. You won't be disappointed.
Love this helmet. It looks nice, works great, and is comfortable for an entire day of skiing. Great value! I would recommend.
Bought this for my 13 year old for skiing.I think it's a great value for the $. Looks and fits great!Like other reviews, I believe sizes run a little small. I got him an XL and believe he can wear this for a couple more years.
The helmet is very well made of durable materials, is light and comfortable, looks great, and comes in a wide variety of colors.Are there other snow sports helmets with all of these features? I haven't found any other, and at this price and quick delivery this was another very good purchase! I highly recommend!
My kids saw that we got this for our oldest since they each had one that fit. They all want this helmet. It is adjustable and very nice looking. My son and husband said the fit is really great. Very comfortable!
I am so pleased with the quality of this helmet. It is super stylish, comfortable, and affordable. I ordered a large after reading several reviews about the size running small, and it fits great. It has a turn wheel in the back that adjusts size to the perfect fit. The matte finish feels great and looks amazing. I couldn't be happier!
The little adjustable turn wheel in the back for sizing was easy to use and I could adjust it during the day&#8230;although I only needed to once or twice. the strap was not painful and stayed put. the little pad under the chin moved around a bit, but I didn't really notice needing it. It looks nice and was a good fit. Great purchase
I bought this helmet for my 5 year old son based on its high review, great looks (have the matte black one) and good price. My son has been using it for a year and loves it. It fits well and looks great. we had an issue with the back strap and contacted the company to get it repaired. They were extremely responsive and responsible. They sent a new replacement helmet within a day. I'll definitely buy their products in future.
