I'm in between sizes in nearly everything. Any recommendations for someone with a 21 7/8 head?...I would like to use it both for summer and winter (with and without a beanie underneath).
Go with the medium/large size if you don't have an opportunity to try it on, but see if you have a chance to try it on before you make a decision.
I would suggest a medium large also, and with the scroll wheel in the back it will help dial in the fit. If you still wanted to try the helmet on, most local outdoors stores should carry this helmet. I know my local REI carries this helmet.
went with the M/L. ended up a little big with nothing underneath, but it still stays on my dome.
