Don't have a lot of experience at this but been kicking around on borrowed ATVs off and on for a while and buying my own this spring.
What are you wearing for gear? The fancy looking motocross stuff seems ill fit for Alaska where we are in mud and crossing running water on a regular basis.
I have worn combinations of hip boots, waders, and HH impertech and have yet to find the right pants / boots set up. I want to be waterproof from the waist down, yet not have water run down the hip boots, I want boots I can actually walk / hike / work / hunt in yet still have dry feet.
I found these, they are close to what I think would work...
Anything better out there? What are you guys using?
