I have wheeled with Tim and Mike for over 10 years There both as good as it gets off road. We have done a lot of exploring in the Moab area. They are a
assit to RME.
I agree with Cody. If you walk by it your just guility. When i smoked i would field strip the filter and put it in my pocket. The wife didn't like washing them when I would forget to take them out
