The all-new RK50 rucksack is our expedition-size roll-top. To manage the extra load-carrying capacity, the RK50 comes with two tubular titanium frame stays as standard, plus a removable hip-belt whose design is stolen from the venerable AK range. For those who love roll-top style bags, the RK50 is one of the largest models available, and probably the most confortable on the market.  This is the new 2020 model and features a new removable front/side compression system.
