In general I find them pretty hardy. I tend to avoid long tails, especially if I am going to be in the car or something, but I would do that too with CSGM for the same reason.
They are easy to spot clean, wrinkles fall out pretty quickly, and I don't worry about them in the rain. Easily ironed if you do have to spot clean, and I don't seem to suffer from snags any worse than only other format I have (CSGM, 90, 45, twilly, maxi twilly) and usually seem to fare a bit better.
The Astrologie moussie that is out right now is really pretty!
