A pouch can include a first wall, a second wall, and a lower gusset that extends from each of the first and second walls. The pouch can further include an upper gusset that extends from at least the first wall. The pouch can further include a seal region at an upper end of the pouch. The seal region can be opened to yield an opening through which the contents of the pouch can be accessed. The opening can be at least partially defined by the upper gusset and/or the upper gusset can define a pocket that can maintain external debris therein as the opening is expanded.
