I'm branching this off from the "How Was Your Commute Today?" thread.

I was disappointed that my expensive Goretex doesn't seem to be as waterproof as when it was new. My rainpants & jacket aren't all that old, maybe 2 years, but I have worn them a lot. But, they're better than anything else, and I carry dry clothes to change into.

I have ziplocks of every size, including very big! Typically I put my clothes in a plastic grocery sack, and then double-bag it. I use the ziplocks to carry papers and books.

I do not want to have to tell my students "The rain killed your homework" OR "The cat ate your homework". Both scenarios are quite plausible.
