I own the older version without the built in gravel guards.
I like them without the gravel guards because I can use the one I want.

But about the wader it self:
I like them since the wader can be worn up or down at the waist.
The only thing I don't like are that the neoprene feet are too big compared to the size. I wear a size M and the feet are size 9. A size 8 feet might be matched better with a M.
