Fjallraven Greenland Top Backpack

G-1000® Heavy Duty | 65% Polyester / 35% Cotton: G-1000 is tough, but G-1000 Heavy Duty goes a step further. Impregnated with Greenland Wax on both sides, it takes durability to a new level. This does mean it’s less ventilating than regular G-1000, so we use it for products where resilience, rather than airflow, is a priority. This translates to reinforcement materials – on places that are susceptible to extra hard wear – and for many of our bags and backpacks.
