Do you know how long it will be until you have the One K Defender Helmet in Navy ? (small)
A shopper on Jan 24, 2017
BEST ANSWER: The Navy (small) does currently show available.
What is the difference between the regular and the long oval shape of the helmet. Also I wear a size 7 in a helmet and I don't want it too tight, so would I go with a medium or a large helmet???
Linda D on Aug 1, 2016
BEST ANSWER: One K advises us that the fit is the same except the long oval is longer front to back. We were not able to obtain specific measurements for the difference. Since your hat size is at the top edge of the Medium size, unfortunately the only way to know for sure which one fits best is to order both sizes and plan to return one. Please bear in mind you would be responsible for return shipping costs as we cannot guarantee fit. Or, perhaps you can try this helmet on at a local tack shop to find out your size.
