It is an upgrade for flexible bottles, which mimic the shape of a hard bottle, compress like a soft bottle and reduce weight by 50%. It features a dust cap and a twist drinking nozzle for easy hydration, along with a bracket handle for safe carrying. Standing upright like a hard bottle, it packs to pocket-sized when empty, ensuring ultimate packability in bags or bags.
