A DOT rating is done by the manufacturer. The empty shell of the helmet needs to withstand a 10 foot drop fall, and it has to cover the head. That is it.
It is not enough because the results of a DOT test are conducted in house and are not done with any oversight by the DOT itself. They are only randomly independently verified. So if you trust the manufacturer, and it is a major brand, a DOT rating might be safe, but again maybe not. There is just no way to know.
The part of the helmet that really protects your head is the foam on the inside of the helmet and that is not tested in a DOT test. It is the foam that compresses to take the brunt of the impact to your skull. A SNELL rated interior has been crush tested to be sure that it is the correct consistency to take the impact..... Too soft and your head will take a hit against the shell, too hard and your going to hurt your brain.
SNELL is a test done independently of the helmet maker, and the test is done on the shell AND on the liner and foam. Anything less than a SNELL rating and you are taking a chance that the helmet will not do all it can.
ECE is the Euro version of DOT, but it is slightly more tough to pass. In addition to a drop test, they to a flex and pressure test for ECE. Unlike DOT, ECE is also independently done from the helmet maker.
Yeah, my one concern is the lack of Snell certification.
The photochromic lense is pretty cool though.
If its for riding.....I say go with Snell that is comfortable for you.
In terms of drag.......Snell approved and cheap works.
But don't all these helmets depend on the shape of one's head? I know my head is longer than it is wider (oval to some extent) while others' heads are more circular. I say you try them on and see what feels good for a price you can handle. This is where internet purchases or ordering without trying a helmet on can suck and take too long after returns and such.
