in my search for the perfect fit i found a lot of information regarding head and helmet shell shapes. the following is copied from a post on another board i thought might help here for anyone looking to get a new lid:
What head shape do all the major helmet makes/models fit?
Given the significance of a proper fit in a helmet, it's unfortunate that more manufacturers don't advertise the head shape of their various helmet models. Maybe some manufacturers don't advertise this information because they don't want to limit their potential market at the outset to only one segment of the population (i.e., oval shaped heads). It's also hard to define exactly what "oval" or "round" mean. I can also understand the reluctance of manufacturers to advertise a particular helmet head shape for fear of potential liability on the part of the manufacturer and/or retailer for selling a "round" helmet to a person with an "oval" head.
Regardless, I think it would be helpful to everyone interested in getting a helmet that fits properly if we created and maintained a list of the various helmet makes/models and the general head shape they fit. Of course, this list would obivously come with a disclaimer that it is based on subjective reviews and is only intended to provide general guidance to help narrow the field of potential helmets for a person with a given head shape.
Let's limit this to current models (or last year's models for people picking up closeouts/clearance models).
Edit-->For convenience and consistency, let's narrow this down to the 3 most common head-shape categories used by webBikeWorld in their helmet reviews (described in their helmet FAQ - look up webbikeworld.com)
The 3 most common shape categories are:
Oval - Sometimes known as "long oval", which is said to be the most common American head shape;
Round - [self-explanatory]; and
Earth - The Earth shaped head is somewhat wider in the middle, approximately near the temples.
Now for the helmets, listed by manufacturer in alphabetical order (If anyone has input on these helmets or other that aren't yet listed, post your comments):
AGV
XR2: Oval
X-Vent: Oval or Round
Arai
RX-7: Oval or Round
RR4: Round or Earth shape
Corsair: Oval
Quantum II: Round or Earth shape
Astral: Oval or Round (more round than oval)
Signet: Oval
HJC
AC-10: Oval
AC-11: Oval
CL-14: Round
CS-12: Oval
CL-Max: Round or Oval
KBC
VR-1: Round (This one seems to be across the board. People with head shapes from Oval to Round to Earth say it fits them well. Personally, I have a Long Oval shape and the VR-1 fit fairly well for a few months, but it started to really loosen up on the sides/temples after a while--it was worn daily.)
Racer 1: Round or Earth shape
Wolf: Round or Earth shape
TK-8: Oval
Nolan
X-Lite: Round
OGK
FF-3: Round
FF-4: Earth shape (one poster considers it a long Oval???)
Scorpion
EXO700: Round or Oval
EXO400: Oval
Shark
RSR: Round
Shoei
RF1000: Round (fits some Ovals, as described below. Other Ovals can't stand it--too noisy.)
RF-900: Round
X-11: Oval
TZ-R: Oval
TZ-1: Oval or Round
Suomy
Extreme: Round (fits some intermediate Ovals)
Spec 1R: Round (fits some intermediate Ovals)
If you know your own head shape and what helmets fit and don't fit, post your experience and the helmet make/model and your head shape. I'll add to/edit this list periodically based on responses.
