What purse do you wear when going somewhere dirty/dusty/muddy/thorny?

What purse do you like when you go somewhere that is dusty, dirty, muddy, thorny, or otherwise not friendly to fancy stuff, but still need to carry stuff with you?

I personally like my (secondhand) travelon crossbody. I've worn the same one in black for almost 10 years and it never got torn on sticking out nails or thorns, and I've only recently switched to a different one in tan because I wanted to wear a different color. It's a crossbody, so it's definitely staying on my body, and this particular brand has all these safety features that I don't necessarily need because I don't live in a city like London or something, but seem to work just as well making sure my bag doesn't get torn on branches, and the zippers clip shut so no spills.
