Hydro Flask Tracker - AirTag | 黑色

I was skeptical the hidden AirTag pocket would be noticeable, but it's completely invisible once the boot is on. The TPU case feels sturdy enough for my daily commute, and the 40oz bottle sits snugly with zero wobble.

It fits my 32oz bottle perfectly once I added the Flex Boot, and the TPU sleeve is thin enough that I barely notice it's there. Now I can toss my flask in a bag without panicking about leaving it at the gym.

The hidden AirTag slot is so discreet that it took me a minute to find it, and the TPU feels sturdy enough to survive my clumsy drops. It snaps into the Flex Boot and keeps my 40oz bottle traceable without adding any bulk. Exactly what I needed for misplacing my bottle at the gym.
