The SixSixOne Evolution Carbon helmet is similar in style to the TLD D2 but with a bit more comfort and design perks.  It is cheaper, a bit heavier, and this particular test helmet had some quality issues, overall a though a great helmet. The shell design has a small profile and helmet offers a completely removable padded liner and is well vented.

The Evolution carbon offers eight vents for your head and three in the chin guard. The vents are screen covered with the largest chin guard vent also having mesh cloth.  One this test helmet the glue for the screens on the chin guard had some issues.  Plainly it wasn’t enough and one screen has popped loose with the other one half way undone.  I’ve talked to SixSixOne about this.  They said the first run of helmets had some QC problems with the screen glue, but all should be good by now.  If you’d had any issues or not, please comment.  It could just be that this test helmet was an outlier.

The visor has a good range of movement and the visor adjust screw is easy to access and adjust. The side adjust screws for the visor are fairly flush with the helmet profile and shouldn’t be an issue when sliding along the ground. The visor is about average width and size, not being as wide as the D2 or as small as the Aatma.

The inner padded liner for this helmet is very well thought out and appears to be well made. The cool thing about it is that it kind of floats inside the helmet.  The bowl of the liner is a bit smaller than the bowl of the EPS liner, so, it feels like it is a super thick and comfy liner without actually being one.  Also this allows the shape of a riders head to define the shape of liner rather than the head having to fit the shape of the EPS and padded liner.  A co-worker hear has a radically different head than mine, almost Egyptian pharaoh like, and the helmet fit both of use very well.  Very awesome.

Also the padded liner comes out as one single piece that that includes the side cheek pads. There are two metal snaps on the cheeks and a bit of Velcro, but otherwise the helmet is held in place with hard plastic pinched between the EPS liner and the shell. The padded liner itself varies in form, from soft padding to a screen mesh for air flow.

The EPS liner has six very large venting holes along the top of the head, four for the forehead and another two for the rear. The EPS liner is very thick on the top and front of the head but a bit more thin along the back and sides (another compromise for a small profile helmet.)

With Helmet On:

This helmet fits similar to the TLD D2 with a couple distinct points of differences. One, the floating padded liner fits to your head and there is a lot more room for my ears. Getting headphones on while wearing the helmet is simple

The cheek pads for this seem to be about as soft as the D2 or Dainese, They sit against the cheeks without squishing. The cheek pads run from the temples to about half way on my cheeks. The padding around the face has some gaps in it that let air flow to the head and ears.

The padding on the inside of the chin guard is softer than some other helmets. I feel like I wouldn’t mind as much having my jaw slammed into it in a hard impact. Speaking of the chin guard, the first time I put the helmet on it seems that the guard was closer to my face than with other helmets. I talked to SixSixOne about this and they said that is the first they have heard that. They said they actually increased the length this year. I figure my perception of the chin guard being short must be because I am right on the cusp between a L and XL helmet.  Also the padding inside the chin guard is thicker on the Evolution than the D2 which could help make it seem shorter. Whatever the reason the chin guard never got in the way or had any visually impeeding effect.  My co-worker who uesd the helmet and had a bit smaller of a head than I didn’t mention a thing.

The helmet meets and/or exceeds the 105 degrees of peripheral vision standard laid out in the CSPC standard.

The helmet is similar to the D2 in that is rides a bit higher at the back of the head and it settles about even with my jaw bones. So even with me being  just at the L/XL cusp, the helmet fits very well.


Cleaning this helmet is very easy. The padding is fully removable and in one piece. Metal snaps keep it in place as well as hard plastic pinched between the EPS liners and the shell. Getting the liner back in place was a slight bit more trouble than some others, but I found when squishing the plastic between the EPS liner and the shell if you push it in at an angle it helps.

Fits Similar To:

TLD D2, the main difference being the greater room for ears and floating padded liner. The helmet seems to have a more oval than round shape on the inside giving a snug fit around the side, very top, and back of the head.


The Evolution fit the larger Blur B-1 goggles just shy of fine. A bit more room than the TLD but not as much as some others. 

Leatte Brace:

coming soon….

Value Rating:

This helmet is a great value. At about 100 grams heavier than a D2 Carbon but about 100 greenbacks cheaper, it should be a helmet to consider. Besides the slight imperfections in the plastic molding around the face, the helmet offers a light weight vented helmet at a competitive price.

Overall Rating:

Overall I think this helmet offers a great amount of features and quality.  The floating inner padded liner makes it so that this is almost a perfect fit of anyone who tries the helmet on.  The one complete liner as well is very nice, and being near $90 less than a TLD D2 Carbon you’ll be very happy with your helmet and maybe have some money to take you date out to dinner.
