My husband has a 58 cm head and he says the sm/med is a bit tight. But would the L/XL be too big?

I have no idea what 58 cm is nor do I have access to a centimeter tape. If the sm/med is too tight, then it was be most natural that the L/XL should fit. The bonehead straw hat is slightly expandible and it would be my opinion that it should fit very well. I like this hat very much and it is very comfortable, wears well and looks good. So good I bought another one. Hope this helps.

My hat size is 7 1/4 and I got a medium. If you wear a large helmet I would get a large

I wear an adult Medium. Just measured my head - it's 22 1/2 ". Personally, I would probably get a small. Good Luck

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

Helmet is roomy. I have a sm md and lg and I can wear my sons sm. The adjustable strap is very user friendly and provides a lot of range...more than a bike helmet. It's also pretty warm. I wear a thin balaclava in cold conditions ( sub 20 degrees) and all is good.

I bought a large and my pack is 80L. I think they only offered large when I bought mine though. My pack fits in the large with extra room. If you were looking for a more snug fit a medium might be the better option. I would just buy both and return the size you don't want after you try both of them out. Good luck

I'm a heavy-set 6'1" and I got the XL. They fit my waist fine, but are long on me. I think the L would probably have been better for me, so I think your son will do fine with the Med.

I have a large head as well. Have not had a problem, find them very comfortable. Like the gentleman state below as well, they are adjustable so they should fit any size noggin.

i wear the same size hat and I bought a medium that fits perfectly - I can even wear a skullcap underneath if it gets cold.

I use a motorcycle helmet L size, and that headphones fits my head exactly. probably tighten a little

I'm not 100% sure. Keep in mind I'm a man. XL barely fit my wife (36D). A M might be tight, a L might be a little loose. I'm a man, I'd say go with the tighter one, but a L might be more comfortable. don't go with a small.

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.

Yes, a large will fit a regular adult man. Extra large is okay too because the helmets are adjustable. Great helmet!

I'd recommend an XL. It sounds like we have a similar build, and I find the plain large too tight.

You might want to try one on at a local place? Or measure the head and look at the sizing chart. The Full90 is adjustable with Velcro to give a more custom fit. Didn't want one too big because you need it to stay on the head. We got the sm/med for my 11 year old.

I can't say for sure but I think there are only 2 sizes s/m l/el so you want the bigger of the 2. I wear a 9 and the sm/med was good they are very tight anyway
