Yep I wear a Gath (there are some better options out there these days) and a vest.
Sure I look like a bit of a kook but better kooky than dead I reckon.

Fashion has never been my forte anyhoo. *see foot note*
I am a sound guy (no not sound of mind - sound engineer) and a bonus of the Gath is being able to stop water gushing into the tools of trade (ears). Last night I mis-timed a run at a wave and caught the impact as it pitched - bamm OUCH!! - side on and no blown eardrum.


. I have also been whacked by my bar on the helmet heaps of times and have thougt go, go Gathy every time!
The downside is not hearing others clearly and I find you feel a bit 'divorced' from the wind direction - especially if you have a wetty on. Weird I know.
Upside is of course live to ride. Oh and it used to keep my hair outa my mush and eyes. Very handy indeed.
Go the helmet so you can go harder I say.

PS I am currently sporting a 'forgotten member of Wolfmother' hairdo. A bogun at Flozzer trying to impress his mates last night asked me "Hey mate where did ya get ya haircut? nerf nerf nerf" response "Somewhere cut-price obviously" Bogun looks at mate for some kind of explanation "erm righto"
