RNAV I'm am in the Petrochem Industry, but very sensitive to any further hearing loss (USMC, large Caliber Fire arms, very noisey work environment etc) and do have a hearing loss, I wear molded Silicone ear plugs at work (those work very well)
I might see if the LBS will let me test ride the Air Attack, I think with the design and the lens should direct the air past the ears.
I will also adjust the straps on my MTB helment to lay flat against my face and bracket my ears in the triangle.
I have a Quadlock coming, so I can look at the info and leave both ears open.

Thanks for all the good suggestions, the glove mirror idea is great.
