The waterproof Raincover 40-60L from Jack Wolfskin will cope with everything from a brief mountain shower to persistent Irish rain. It is designed for trekking and hiking packs with 40 to 60 litres capacity. The cover still allows full access to the pack's suspension system. The draw cord makes attaching the cover quick and easy. Simply pull it over your pack, adjust it to the right size and you're done. When not in use, the cover stows compactly in your backpack.
