I was very close to buying one when they were available from Blacks a while ago, and £20 was a good price, but I figured that I wouldn't use MORE than what I already have, and while the extra space is good I'd just end up weighing myself down more and taking more stuff than I need

There's still a bit of me that wants one though, would be good on a big day ride. This is what I have, not waterproof but pretty robust.




btw the Batpacks are £25 here - http://www.gaynors.co.uk/brands/montane ... /batpack-6
