Adjustable covers, systems, and methods are presented that include an adjustable cover that may be adjusted to an appropriate size by hand without requiring cutting tools and without substantial leaks. In one instance, the adjustable covering includes a drape member with a plurality of non-leaking tear paths. Each non-leaking tear path includes a weakened path of the drape member that may be torn. The adjustable covering may further include a first plurality of tear starters formed on a first initiation edge of the drape member. Each tear starter of the first plurality of tear starters is aligned with one of the plurality of tear paths. Each of the first plurality of tear starters is adapted to facilitate the initiation of a tear along a tear path. The grains of the drape member, a backing layer, and support layer may also be in the same direction. Other adjustable covers, systems, and methods are presented.
