Good stuff about cloaks from the guy who does weapons talks.
A lot of people believe the anti-cloak propaganda of Diana Wynne Jones’ Tough Guide to Fantasy. No, cloaks are good. For some purposes, they’re better than coats; for other purposes, they’re less good but still useful. (But yes, rolling up in only your cloak isn’t advisable; you’ll want at least another blanket beside your cloak, and a ground sheet.)
