Hi Trekhawk,

I bought the AmFib a couple of years ago, and they are just wonderful. But, at least in the edition I have, the super-waterproof fabric is in the front only. Nevertheless, it's been doing a great job.

Like denise says, do shorts first, then the AmFib seems to be good down to about 30 degrees. An extra set of tights (I have castelli bib tights) in between takes it down further (if you dare!).

And, best cold weather trick I've found, Toe Warmers!

Have fun!
