Ideal for use in situations where a pack cover may be impractical (for instance where a cover may snag on undergrowth, or for external frame packs where a cover may not fit over the pack). The pack liners are shaped to fit the internal contours of a backpack, so the base is oval, rather than round, and the liner has an overall tapered shape. Protect and organise your gear while hiking, trekking and camping in any conditions.
