Sizing: My dirtbike helmet sticker says 57-58 cm so I'm guessing I should get the S/M but I have a big nose, to much pressure gets very uncomfortable?

If your head is larger than that of a typical 7th grader even the XL will be TOO small to fit over your mouth comfortably. In addition, it will FLATTEN your nose. This is, however a very well constructed garment and is well suited for a child!

Go with the next size up. That s/m is too tight for me, and I am 5'5" at 165.

This is what I used to make sure I got the right size. Hope it helps. Its from the Lucky Bums website. Remember size is in Centimeters. Look at where it says "Snow Sports Helmet Sizing Chart". I think I was between sizes so I went to the next largest size. Nice thing about Amazon, you can always exchange it or refund if its not right.http://luckybums.com/sizing-chart.aspx

I found that these helmets run large in half helmets . I own full face LS2 and this one also . Now the full face seemed to run true to size but the half helmets seem to run larger . I usually wear a medium helmet to accommodate a turtle fur underneath , but in this helmet the medium was way too loose for me even with the turtle fur underneath , So I had to go to a small . Again everyone's head is a bit different so sizing may vary per individual . In my case the medium was one size too large and I downsized to a small which still is roomy even with the turtle fur underneath . I probably could have went with the X-Small but didn't feel like returning it again to change sizes again . Hope this helps . I found that these helmets run large in half helmets .

I think a large would be fine UNLESS!!!! you have a large wind shield or panniers then you would need up go up a size, The large size fits my 20012 honda cbr1000r perfectly, for reference

The look will be ok depending on your personal style if you care about that stuff. I would say that the helmet is a bit more heavy than the standard bicycle helmet. it's about 2 to 3 pounds, give or take. Good protection. The strap is not that easy to put on and take off. I don't know how fast you go on your bike but i really like that it doesn't rise up with the wind and i've gone as fast as 80mph.

It depends upon your hat size. I have a large head, 7 1/2 hat size, and a wide face, and typically wear "L" or "XL" helmets. This one fit fine, but was a smidge snug at the temples. However, after a couple of hours, the foam compressed and it fir perfectly.

You may have a head shape that is long front to back, and a different manufacturer may use a mould that is more oblong rather than round. I tried on several helmets that were too tight front to back and rejected that manufacturer hope you find the right fit.

I would say get whatever size hoodie you wear now. I bought mine XXL like my jackets and everything else, and its just a big snug, but that's how you want this jacket to fit when you are riding.

Trust me the helmet runs really snug and comfortable I have a medium it's perfect even for a big head.

I suggest you go to a local bike store and see what fits you best. I am 175cm and i prefer a large. but it is recommended that i ride a medium so up to ur discretion

I measure 23 1/2. The "large" that I have been using is "snug". I would suggest that you need an X-lg. The padding in this one leaves creases in my skin, but is ok. I highly recommend this helmet because of the quality and extra protective coverage on sides and back. How often would a rider land on top of their head. I've taken a few dives and if my head did hit the ground, it was on the side not on very top.

The best thing to do is to go into an actual store and try on the helmet to figure out what size fits you best...then order it at a better price from Amazon! Watch a youtube video on helmet safety and proper fit!

I would recommend the xs-s. I run a riding program and have every size and that is the most common size worn. We all love the comfort of this helmet!

you could go with the small and just ensure that the helmet is tightened down as far as it can be for max protection

I am 5.4, I bought the small which was 50 cm. It is a little too big for me, but I still ride it with no problems. Hope this helps :)

I bought a medium and a large helmet. My head measures 52 cm so I wear the medium helmet but I wish I had purchased a small. These helmets seem to run a little big. I suggest a medium. You want it to fit tight.

They are dial adjustable. Mine is an XS/S and fits 51-54 cm. If your head is more oval shaped than round shaped you will probably like this helmet.
