Does anyone know of a good place to buy a large rucksack (60-70 l) in the "greater London area" ? A wide variety of rucksacks to try on is essential, as my wife (who this is for) has a back length that makes many rucksacks not fit properly. Knowledgeable staff would also be a plus.
We've tried Cotswold, Ellis Brigham and Snow+Rock in Covent Garden, but didn't strike joy.
