This 58 litre waterproof rucksack liner will protect your gear from the elements and can be used as an alternative to an external pack rain cover. The liner is constructed from ultralight 40D high tenacity nylon with a waterproof coated fabric and seams to keep water out. It also comes with a fully waterproof roll top closure for added protection. Unlike many other liners, the Osprey rucksack liner comes in a squared-off shape, which makes for more efficient packing by utilising the interior shape of rucksacks and backpacks, it can even stand unaided when removed from your backpack.
