The problem is clear to everyone. When I want to dry the camelbag, water always remains somewhere, it dries for days without success. That's why I invented a holder on which the camelbag can be slid and left open to dry. Since I have both 1l, 2l and 3l camelbags, this holder can be adjusted to any width and size.
