Firstly they are NOT 35L. About 26-27 liters by my calculations. Even if you add side pockets, you still don't get another 8 liters. Givi exaggerates. They're narrow, tall and tall - just what you DON'T need in a holdall. The main pockets have large vents at the bottom to keep water and dust out. Using the provided stuff sacks is not an option, it is a necessity. They're fairly heavy for soft luggage - with adapters, they weigh about 8.5 pounds on each side, which is only 3.5 pounds lighterโฆ
