Customer Reviews for Dexter Atome Hammer - Black / White / Red

Dexter Atome Hammer - Black / White / Red
September 14, 2017

Nice helmet, shame about the visor

When deciding to buy this helmet I read the only other review on it and was only mildly concerned at the time about the part of the review where the person said that the visor was not the best and after now buying it I can see why, it was clearly not the same person that designed the visor and the helmet, as the helmet appears to be well thought out but the visor change out mechanism design is poorly thought out, it requires a lot of effort to change out, to such an extent that it feels like your going to break it as such is the force required to remove it from the helmet. I have changed out visors on lots of other helmets over the years from Arai to ls2, none were as hard as this, Dexter you really need to back to the drawing board on this, oh and yes the video on Youtube makes it look easy, its not. On a side note the website ( Sportsbikeshop) said it has a drop down internal visor, it does not have any, ( didn't bother me as it came with a free dark race visor)so be aware, at the time of this review it still had not updated its description despite my contacting them to tell them this weeks ago (Come on lads). So helmet is 4 stars and visor is 2 stars. If you can see yourself only changing out the visor occasionally maybe you can over look this as it is a nice helmet.

Very good value lid, visor not the best

This helmet feels a level above where it is priced at. It's nice and light with a good quality liner. The only down side is the visor. It was a real pain to fit, taking a lot of force and felt like it could break before it snapped in. It feels a little flexy too when lowering from fully open.
