Humangear Stax is a modular system of watertight stacking containers.
No more loose containers that you have to juggle in your hands. With a simple twist, the containers are connected. The ClipHandle not only offers a way to hold the containers from a loop, but it also acts as a clip, so you can hook one container or an entire stack of humangear Stax to a backpack.

The lids have silicone gaskets for superior sealing.
