HydraPak Stow Flexible Water Bottle - 1L - 28 mm Cap - Mammoth Grey

HydraPak Stow Flexible Bottle - 1L - 28 mm Thread - Mammoth Grey is an ultralight and highly functional flexible bottle that will revolutionize the way you carry water on your expeditions. Thanks to HydraPak's innovative design, this 1-liter reservoir combines the durability of a traditional bottle with a compactness that allows it to be rolled down to the size of a clenched fist when empty.

The Stow Flexible Bottle model in Mammoth Grey has been designed for survival, bushcraft, and ultralight trekking enthusiasts. Made from durable thermoplastic polyurethane (TPU), it is characterized by high resistance to mechanical damage and extreme temperatures – the bottle can be frozen or filled with water up to 60°C. The use of high-frequency welding ensures 100% leak-proof performance, backed by a No-Leak™ guarantee.

One of the reservoir's greatest advantages is its compatibility with 28 mm threaded water filters (e.g., popular Sawyer filters), making it an indispensable component of any field filtration kit. Equipped with a convenient, screw-on drink nozzle with a cap and an integrated carry handle, it allows for easy filling, drinking, and attaching to gear.
