You're in that London
So blacks, ellis brigham, snow+rock. all around covent garden.

I've got a Cross one for off-piste skiing and a Berghaus one for general shenanigans. In case you cared.

Tell me about your sac shenanigans.
This one's for travelling around India. And then all sorts of things, innit. It has to be an investment, not a shoddy thing that will break in two weeks.

buy a double-lined one.
(berghaus do goo ones, I think it's called drysac or something. that way if your shoes get covered in shit, you can put them in the bag but not inside the liner. same with wet clothes. for a hot country, serious mesh venting on the back where the straps are is important so you don't end up sweating line a paedophile in mothercare when you're carrying it.

Otherwise, try them, see which feels comfortable. You're probably going to see little change from £150 for a good one, so take your time and be picky.
