yes, id say a lid is cool. i dont know anyone who gets bagged for wearing one. when you wear one, you get confidence, safety, and respect. its not that hard to put it on..
I wear my full face DH helmet when DJing and riding street, as well as for actual DH and FR I only ever wear my 'spiked-hawk-half-lid' when I ride flowbowls. And as for no helmets... only when I'm walking, or slowly riding back to the trailhead.
Helmets are super cool. Unless they're XC helmets. Those are just brain buckets.
I'm in the same boat. All of my friends hate wearing helmets.
I don't like wearing them simply because they're hot and I always lose mine.
I wear one anyway.
fox makes a superlight bmx style helmet
ive got that helmet its actually rather nice better vented than my old fox xc lid and it weighs a lot less as well and if you wear it you wont lose it XD
