LifeStraw 個人吸管濾水器攜帶盒

Finally found a case that keeps the straw secure in my daypack without rattling around, and the fit is snug enough that it doesn't shift even when I'm hiking. The opening is easy to access one-handed, which matters when you're setting up camp in the dark.

The case fits my filter straw perfectly and feels sturdy enough to toss in my backpack without worrying about damage. The zipper is smooth and the material seems like it will hold up well on muddy trails.
