I use a Pelican micro case for GoPro, charging accessories, and other stuff when sea kayaking. So, as you might imagine, I don't $#&! around with water protection! :-) Works like a charm. My only complaint about them is that the rubber padding is also the o-ring seal, so you can't remove the padding without removing its waterproofness, unlike a standard Peli case (which has foam and a separate rubber o-ring).

They're all too small to carry something like a PCM-D50, though. I use a Pelican 1120 case for my PCM-D50. It's a small Pelican, not a micro Pelican, but it's the right size. The 1100 series surprisingly petite; the hardware is scaled down from the 1200-1700 series.

I've not messed with the Sofi-Cases either, but for large cylindrical objects, my suggestion would be waterproof dufflebags from Watershed. I keep my DSLR and a big, long lens in one, tucked in my kayak cockpit, for wildlife photography, and it's surprisingly bombproof. They would, if you get the right size, accommodate cylindrical bits like Rycote windshields.

Hope that helps!

We have a couple of the smaller Pelican waterproof cases at work. One holds a small collection of lavalier microphones, and several others are used to hold 400 series Lectrosonics wireless systems. The cases we have will hold either one receiver, or two transmitters. They're aweseome little cases, and not TOO bulky. Good for keeping small items organized and protected.

As for the Rycote systems...yeah, we use Pelicans at work for those as well. I've been meaning to check these out to: http://www.alfacase.com/Softi-Case.html

First noticed them on Tim Prebble's blog. I wonder if they'll work for the full windshield systems. Their "Combo Case" is pretty interesting as well.
