Vango used to be good quality some yrs ago.. then they went huge and aimed at budget packers too.. so be wise in your choice... ex military shops offer some good value back packs whitch contain a simple wrap around nylon cover for that bit of added security esp at airports its lockable but easily cut open with a stanley knife .. but it instantly tells you its been broached.. if ever that happens.. good value for money too around £80.. ideal if ur only carrying ur regular stuff.. i normally carry a smaller back pack for flights which comes in very handy too for 2 or 3 day outings.. if its of any use Tk max have some good back packs for two or 3 dayers around 30 £ nike offer some nice gear too.
