So on the back of my helmet is a knob that you can turn to loosen or tighten the helmet. I am assuming this is the same.

I have a medium and I wear a 7 to a 7.25 in a cap size. It just matters on the circumference of your head.

I bought a size large for my 6'3" husband & wanted a design on the helmet. I think the design was what cost so much in my case. I am not able the compare the products you are asking about but if the same company makes both helmets then I would think the difference is the seller(s) description; one seller wrote out the size and one seller is selling for much more. Sorry - probably not very helpful. Good luck.

Don't get the helmet. It is just too damn big. I still use it. I feel safe with it. I am too cheap to splurge on a new one yet but it is dorky bigggggg. i am not sure about the size and I am too lazy right now to check for you. Good luck. If you do get it, it is a decent helmet.

You are on the edge, in between the two sizes, more towards the s/m. here is a link you can look at. for normal hats like cowboy hat I wear a 7 3/8 and I got the m/l helmet and it works great.hope this helps.. http://blackdiamondequipment.com/en/climbing-helmets/half-dome-helmet-BD620206_cfg.html?dwvar_BD620206__cfg_color=Orange#start=4

tough question because every company has their own sizing chart. If you haven't already, check their website for a sizing chart. I ordered a Medium. It has an adjustment that is easy to use with the helmet in place. The range of the adjustment is pretty impressive. It can go so small that there is no way I could possibly get my head in it, and yet it can get so big that it would easily fall off of my head. My head is 22.5 inches around (just above the eyebrow). That's the best I can do.

Mine measures 22.25" around the head and fits fine, neither loose nor tight. I normally wear a medium hat, but a large when wearing these underneath to absorb sweat. I've worn these when falling off horses and they've stayed put. Hope that helps with your comparison.

I would go with the medium, you can adjust down using the wheel at the back of the suspension inside the helmet. If it's a little too small you'd have no room to adjust.

I just called Bell customer service to ask the same question. My daughter is 3-1/2 and her head measures 19.5 inches. They said that this helmet is the right size for her. They measure in centimeters and said this helmet fit the range of 47cm to 52cm (about 18"-20"). Hope that helps!

Aha! I went online and researched - take a tape measure around your head at forehead level. Mine was like 24 inches I think. Convert that to centimeters, as most helmet sizes are cm. Then there are guides online that equate inches to helmet size - see website below (http://www.telemarktips.com/HelmetSizing.html)

My head size is 59.5 cm and I have a L/XL helmet size for 59-64 cm head size. Perfect fit. With your 56 cm (22.05 inches) head size, a helmet size S/M should fit perfectly for 54-59 cm head size.

Depends on head size. Youth helmet is for 22 1/2 - 23 1/2". Don't know what the adult size is. Doesn't matter the age; I am an adult and would need to get the child size for myself.

I bought adult M for head size 22 inches, 56 cm and I do not need to put anything under the helmet as it cover the ears too. Hope it helps you!

I bought the small for my daughter. Her head is about 20.5 inches and it fits fine. The tag on the helmet says the small it is for 50.5 - 54 cm

The M and Medium options are the same helmet. I don't know about size differences 2013/2015, but they have likely not changed anything. The M/Medium works nicely for head circumference between 22" and 23".

Hello. I am sorry to say that the helmet probably won't fit. I am a petite mom measuring a 56cm diameter head and the helmet is very snug on me. Please keep in mind that this is a youth replica helmet and not to be used for sporting purposes but rather room decoration.
