Good Quality Rucksack / Backpack (off the bike, hiking)

yeah i though that crux looked purposeful no messing no flashy bits just good and proper rucksack

is it ruck sac / ruck sack / rucsac / rucsack by the way ?

Backpack.

Also +1 Crux - used to know the guy who made these. He once offered to sell me a whole load of prototypes on the cheap, but I was broke at the time - couldn't take him up on it.

Still pains me to this day.
