    • Super light, great helmet and SkateRatz is a great seller!
Color: Tan Leopard Matte Size: Large (22")
Review Image by Naturegurl2 Naturegurl2
SkateRatz ftw! I tried a lot of helmets and THIS was the one! Very light and fits perfectly. They even included extra liners and a cool sticker that's going right on the helmet.

    • High Quality
Color: Black Gloss Glitter Size: Large (22")
Fits great, looks great! I haven't hit my head yet but it's giving me the confidence that if I did, I'd be ok.

The helmet fits perfectly on my daughter’s head. It is comfortable, provides safety and looks good on her.

    • Good.
Color: Black Gloss Size: X-Large (22.5")
It has taken a few spills, and done the job. Maybe don't go for glossy, if you want it to look decent after.

    • Love this helmet!
Color: Black Matte Size: Large (22")
I am an old school BMX'r and never wore a helmet. Getting back into it and being more fragile I decided to purchase one. I tried another brand and the sizing was sketchy. The S1 Lifer sizing is spot on. I have a 22" dome and the large is sized for 22". Fit perfect!! Also, great quality, very light and feels awesome. Looks ok too. Doesn't make your head look like a watermelon. Fit makes me want to wear it. Oh, just a heads up, you get extra foam liners to install if the standard liners make the fit a little tight or if its loose you can install the different size foam liners. Really easy, velcro installation. Love this helmet! ... show more

    • Good Helmet
Color: Black Matte w/ Checkers Size: XX-Large (23")
Helmet is nice, although the extra sizing pads were not included. Thankfully S1 directly sent me some. For those with a cranium that is more on the "round" side versus usual "egg shape", make sure to try it out first if possible. I had to step up one size due to this. Other than that it's well made and stable. Straps are comfortable without being itchy. Time will tell how long it holds up. Ventilation is well placed and not overly hot. Dropped one star due to no extra pads, but later sent some after contacting S1 directly. ... show more

    • Not XXX Large by any Measure, See Update
I was hoping that this helmet would fit my 62-63 cm head it does not, uncomfortably tight front and back with thinnest pads. I don't know how they think this is a XXX Large. Otherwise seems to be a very good and high quality helmet but it will be returned. There is just no profit in protecting extra large heads as the numbers that would be sold do not justify the investment needed to make such helmets - molds for plastic items are extremely expensive. I bought a helmet from Triple 8, Model 'Heed', that comes in just two colors, one size, and is made for extra large heads (not available on Amazon). It seems to be identical to their Sweatsaver helmets but is not certified for any use. My guess is that is Triple 8 just did not want spend the time and money in certifying a helmet that will only ever sell in small numbers. Found helmets for large square heads online from Germany but they will not/cannot ship to the U.S. because they are not certified here. Will updated my results with the Heed' helmet. Update: S1 Helmets has a 'Mega Lifer' helmet that comes in extra big sizes. Amazon's search engine does not seem to display it until you include the word 'Mega'. Canceled the return and give helmet to my son who has a 'normal' head. Changing rating because S1 contacted me very fast and helmet does seem to be very high quality, unlike Amazon's search engine . ... show more
