A size medium fits a 58 cm (22.75 inches) circumference head comfortably with or without a light hat or headband underneath. Great helmet!

my kids heads measured 20.5 inches which according to the Lucky Bum sizing chart said would be a youth M/L. Wouldn't even fit over their ears

I wear a standard men's medium hat and my husband wears a large. Our Lucky Bums are both mediums and fit well, although I can wear a ballcap under and his may be a bit snug for that. Sure love the ear flap insulation.

They seem to run small. I got a small size and it didn't fit my 8 year old. I'm estimating under 20 inches in circumference

My son's head circumference is 20.5". I bought a size small and have it laced in the back all the way closed. This fits well on him and allows for growth. From USABarnettSports website (where I got sizing info. originally): Large 23.5" Medium 22.5" Small 21.5" X-Small 20.5" I interpreted the sizing to suggest that it was the largest head that would fit, and so I went up to the small (21.5") instead of the x-small (20.5").

I'm 29 with an average sized head, they fit me fine. I would say they fit adults just fine, I use them for weed eating.

They are very flexible and should fit you comfortably. They are also adjustable but you probably won't need to expand them. My son's head is larger than yours (8) and can wear them easily. Now if only I could find him hats that fit as well...

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.

Measure your head. If you find you are between two sizes, then I recommend her the bigger one. Brainsaver Rubber Helmet Sizing Chart: To ensure a perfect fit, measure the circumference of your head starting in the middle of your forehead and match it with the sizes below. XS 20.10 in - 20.50 in (51-52cm), S 20.60 in - 21.30 in (52-54cm), M 21.40 in - 22.00 in (54-56cm), L 22.10 in - 22.90 in (56-58cm), XL 23.00 in - 24.00 in (58-60cm)

They run the same size as a normal helmet. I suggest going to a local motorcycle shop and trying on a few and see what size fits you best.

I honestly have no answer for this, as I haven't the larger size to gauge for comparison, sorry. I will however state I have a rather huge head, and bought the standard fit anyway, and feel I made the right choice. They seal up more than adequately.

My head size is 21 inches and would also fit someone with 19 inches comfortable. Any head size small might feel loose especially if doing sports.

Fits any size head.My 8 year old granddaughter 10 year old grandson wore it just fine and it also fit an adult very comfortably.I would certainly say it fits most head sizesM

Sorry so late to reply, but I just now saw this. I have a pretty big head (hat size 7 3/4) and these fit fine. They go around the back of your neck, not over the crown of your head.It's possible your head might be too wide, ears too far apart (everyone's head is shaped differently), but they work fine and are very comfortable on my big head.

I purchased a large boonie and my head measures 23 1/8" (about 58 cm) Hat fits very well. After it is washed I air dry to limit any shrinkage. Hope this helps.

I am not sure, but they are adjustable. My son has a very large head and they fit him with no problems.
