Exped Waterproof Pack Liner 80 (Medium) (Closeout):
If it's not the rain or snow that send hikers reeling back to the trailhead, it's the unrelenting assault by moisture that gradually seeps into the crevasses and nooks of their packs, soaking dry clothes, sleeping bags and food. Even if you have a waterproof pack cover, water can still run down between your back and the pack backpanel where the moisture is eventually absorbed through the pack seams and into the main compartment. Your best defense is Exped's Waterproof Pack Liner. Unlike most round-bottom dry bags, this liner is squared to effectively utilize all of the space inside your pack. A Roll-N-Fold closure and Steath buckles further ensure that the natural elements stay in their place.
