Hydrapak says

Fill. Drink. Pack. Repeat. With durable construction and minimal design for easy packing, the flexible Stow™ 500ml helps make all your adventures the best they can be. Add the flip top cap with spill-proof valve for easy drinking, bail handle for comfortable carrying and attachment, and a weight 80% lighter than most hard bottles, and you’ve got a perfectly pocketable bottle.

Our Verdict

Hydrapak’s Stow Bottle 500ml internal baffle really works and keeps the shape of a flask when full. The flask shape is great for packing in your pack, but might be harder to stow on the outside of your pack or in a bottle pocket. The soft, yet durable materials used in the Hydrapak bottles are great for keeping the weight down but most importantly the packsize is tiny once the bottles are empty. The updated cap replaces the twist lock style and is easy to use with a flip top to protect against dirt and less messing around on the go.

A useful option is the ability to use it with water filters (with a 28mm thread) when you’re heading to more remote areas. This saves space by having to take more bottles and makes the Stow that bit more versatile. This 500ml version is great for general use and as a handy option that fits in most pockets when you’re on the trail.
