I have a Rudy Project Kontact -- it is my favorite helmet. I like the fit better than the Giro or the Bell, and it has a greater adjustable range, which means I can wear it in the winter with a cap, or in the summer without. It has very good airflow & a mesh netting to keep the bugs out. The straps are soft, and they have a twisting mechanism that works very well to loosen or tighten. It is not clunky, it is in fact very sleek. It does not sit heavy & low like a hard-hat, it just kind of envelopes.

I have a Giro Pneumo & a Bell Sweep, they both bother me on long rides. They start to pinch & squeeze. I'm more comfortable in the Rudy Project. I've tried on the Atmos in the LBS & won't buy -- the fit was very odd. It does not fit the same way as the Pneumo.
