Great fit, comfort, and look. The strap in the back allows for a pretty universal fit and the airflow is good for hot days. Not so much for the cold but i can fit a beanie under just fine and adjust the fit.

Quality helmet with great tech. It fits really nicely on my (oddly shaped) head. For the price paid it is a bargain. Would like the non-peaked version too!

These were on a massive price drop at the time..£29.99, to be honest I thought it was a mis price, or that these helmets were so bad they had to give them away.How wrong was I, genuinely I was shocked, coming from all sorts of heavily priced “Troy Lee” helmets and such alike, I wasn’t holding out on this 100% helmet, but I think I prefer the fit, the looks to all my other helmets.I would actually pay the £80 RRP these are and still think I have a bargain.Pads absorb well, ventilation is good, secure when on, and looks well.

Liked it so much this was the second one purchased (also because 99 Bikes had a good special on it). Works really well for a plait or high pony tail as the helmet has space inside the helmet for the tight part of the ponytail. Means the helmet actually fits rather than bobbles around like other every other helmet brand (expect possibly one Scott helmet but couldn't find it to try). The hair can go up through the rear of the helmet for good fun factor, or down the back like other helmets. Also the pretend MIPS system doesn't catch on hair making the helmet more comfortable as well. Looked at over 50 helmets and this one the only one with room to work with a high ponytail plait without compromising the rest of the fit. Finally a helmet that fits well (so bought two).
Got it on sale, nice lid. Not tested the crash function yet and don’t intend too!
Great helmet with novel features. good fit and look in the Tan colour.
So far so good, I have done about 30 miles wearing it. Nice ventilation, it fits perfectly. I was afraid of the size bc they come in combined size; I ordered an L/XL. I have to say that it is not as big as other companies that have this type of sizing, so I’m very happy about that too.
Awesome! Our son is almost 12 and it fit him so well. He said, "that helmet's sick!" when it arrived. It is a terrific fit and overall good protection!
I'm right up on the size limit, My S/M took adjustment to get fitting good. The rear ratcheting adjuster needs to be pulled out from the inside of the helmet and placed into it's lower slot. This isn't in the manual and at first doesn't feel as if it's not meant to be removed, leaving me worried I was going to break the helmet. Thankfully it's just a well machined pop in/out style adjuster and once it was out; adjustment was made much easier. While my Giro helmet of the same size specifications goes on/off much easier, with this helmet I have to set to the max size to put on, then tighten to fit snug else the adjusting plastic around the ratchet can get stuck under the helmet causing it to dig into the back of my head. Size up if you can. Well made lid that is a ... MoreI'm right up on the size limit, My S/M took adjustment to get fitting good.

Perfect fit, really comfortable. Took it out for a big ride on the weekend and I actually forgot it was on at times. Solid helmet!
