|Super Light! ~7oz on my scale, compared to 13oz for the newer BD halfdome and 16oz for the older halfdome.|
Very comfy, sits on your head nicely, adjustment is easy, chin strap fits well.
|Possibly ventilation(???) vents are minimal which could hurt in the summer sun, but benefit during ice season.|
Possibly durability- just like all the other foam helmets, it wont take the abuse of a good hardshell lid.
|Similiar helmets, Petzl Meteor, BD tracer.|
Otherwise Look at hard shells.
