Water can seep through the roll-top closure of a dry sack/bag (regardless of brand), so double-bagging is a common sense measure to prevent your phone from getting wet or damaged. Relying on a single dry sack/bag, no matter how new it is or how well it has been taken care of, is not something we would recommend.
