Replacing an old Bell scooter helmet that I used for inline skating, this looked like a great design and concept. And when I received the item - in very short order - it was. The lining is super-comfy, construction is excellent, the shell covers the entire head and is extremely light.
Only one problem: even the XL size doesn't fit an adult head that's on the larger side and sports a full, thick head of hair.
While the Bell Faction Large fits me, albeit snugly, with the thin set of pads provided, the Brainsaver's XL (which covers roughly the same head circumference) does not. And unfortunately there's no way to tune the size of this helmet by swapping out different sets of pads - thus 4 stars, not 5.
But fear not, fellow fatheads! Triple-8 has apparently been made aware of this sizing issue and sells, directly on their web site, an XXL model of this great concept -[...] . Hopefully Amazon and retail stores will also carry this item at some point but, if not, you can get it for now direct from Triple-8. This is the one I'd recommend for an adult who still has plenty of hair.
