I just got a WRSi helmet free and thought id give my opinion on it
Safety- Verry safe, it includes a peisce that supports the back of the head verry well and keeps the helmet from rolling back
Comfort- Pretty comfortable, it comes with pads and stuff to customize the fit, but i found that a sort of pocket can form where your head doesnt quite fit in.
Style- If style is your thing, then this isnt the helmet for you. The actuall design looks pretty cool, but its so big it looks like your wearing a construction helmet on the river. I personally dont mind, but you mind want to stear away from this one if your fashion conscious.
