For my latest trip I've picked up a Zephyros 1 tent, it seemed to be the lightest proper tent before the costs for saving any more weight start to rocket. In terms of size, if I was an estate agent I'd be calling it cosy, compact or easily maintained. It's pretty small. As a shelter for one night at a time it's ample. As a base camp or should you decide to stay in it for a day, you'd probably want something a bit roomier. I'll be using it for my tour over the next fortnight and will update should that opinion change.
+1 for Ortliebs, went through a succession of Aldi and Lidl panniers before biting the bullet and forking out for the Ortliebs, as either the brackets broke or the bottom fell out and besides, they were too damn small. They also weren't very waterproof. The Ortliebs have been in one crash when I was hit by a car and the brackets broke but were easily and very reasonably priced to repair. They've also been for a slide when I came off during the winter with only a few small nicks and a small tear which are patched with gaffa tape (other/better methods of repair are available). Poles apart on pricing but in this case you do get what you pay for.
