The problem with pockets
I have this thing about pockets in clothes. As a woman, I am constantly finding that clothes I buy either have no pockets or have pockets that are woefully inadequate for the purpose of holding anything. Sure, we have purses, but sometimes you need to be able to put a phone, notebook, or packet of snacks in your pocket for easy access.
Or in this case, a chair for the late afternoon at a festival when you’re tired of standing around. If you’re a guy (or a carpenter) then maybe you have pockets this big. For the rest of us, though, there’s no way any of our jeans’ pockets are big enough for this chair. I’d advise taking your own handyman with you to carry it.
