Trakke have started making some lovely rucksacks recently:

looks like amazing workmanship, so great value for money if you can wait for it (recall a four weeks wait from the website);
wondering-mind left Condor and cycled to Brick Lane Bikes - the aim being
after reassessing the Brooks Pickwick and MW's Fitzroy and Vandal, my to check out their usual unusual offerings,

this consisted of the Y Not Cycle range - previously unseen by my eyes;

after testing the Medium and Large size Gulper for the fit of my daily contents, i settled upon the Large, 2012 edition - unaware that there was a fresher-looking 2013 edition (shown below),

given that they're the new-kids-on-the-block, it seems a bit of a pricey purchase (at £195 before matching an LCC 10% discount, to round off at £175) compared to the more established life-time guaranteed Mission Workshop,

but - they are a little different and seem to have the funk, so embracing their offering for now..
