I have to say Simms makes some of the best gear out there.  These G4Z prove that point again.

Some of the nicer features includes:

5 layer gortex over the normal wear and tear areas, those patented front and back leg seams for comfort, 4mm high density neoprene stockingfoot and my favourite is the waterproof center zipper.  The zipper down the front is fantastic and makes these way easier to put on and take off.  It’s nice not having to do the wader dance when you get in or out of these…
